2009 Les Deiner Series

Wednesday, February 10th, 2010

This annual series to remember Les has been running since 1995 and since I had been lucky enough to win it for the last six consecutive years (seven overall) I felt the interest in the series was waning.

Originally it was for pre 1958 machines of any capacity, but the little 7R seemed to be difficult to beat as the series consisted over three or four meeting over the year and hence consistency was critical.

To revitalise the series, we proposed a new competition between the Historic Register and Atujara.   The concept was for any period of historic machine and each club would select three riders for the day with their final class finishing position in two races over the day scoring points towards the final club score.   In addition, the rider would score additional points for their age and the machine age.  Three meeting for the year were selected.

While this sounds cumbersome, with the assistance of a simple spreadsheet made the task relatively simple.   The idea was to reward the older riders and older machines with bonus points, which we felt was in line with Les’ outlook of enjoyment and promotion of the sport.

The final round was at Mount Gambier over the New Year period and while Atujara went into this event one point behind Historics, we were finally beaten by 35 points.

Overall, the series proved quite successful (although we lost) as Atujara had seven riders with eight machines competing, and Historics had 6 riders with seven machines.   We had to try and select the riders and machines most likely to gain high placings in their classes on the day.

Now the perpetual trophy will go to Historics for the next twelve months so that we can lament and hopefully regain the trophy for 2010.

The spreadsheet shows the riders and their appropriate scores.  Thanks to all of the Atujara riders that scored the points for the Club, and hopefully we can achieve a few more points towards next year’s score.   Not only did the Club riders assist in scoring points, but they helped keep Les’ name alive – well done.

RD Racers

Wednesday, July 11th, 2007

If you own, race, or would like to own or race and RD250/350 LC, or just like pulling them apart (I know I do) get on the LC Register.   This is to keep the 28+ members in touch with race meetings, parts, and bikes for sale.   It costs nothing to join, just sms your email and a small note (ie Mike Doohan, RD Racer / own 2,  RDphile@blahblah.com.au) to 0438881519, or email brett.metcalf@atujara.org.au  and Brett will add your details.  
People with RD400’s, TZ’s or other similar 2 strokes are encouraged to participate.

There are lots of riders who can’t do every meeting, the idea is to get as many as possible on the track at the one time.  The race entry forms will be forwarded to you if you have an email address, as well as who is likely to enter, so you can work out which trophy has your name on it.   2008 is likely to see prize money so put the wheels back in the thing and stop tooling around. 

Seniors Meeting – Mac Park 2007

Tuesday, June 12th, 2007

Believe it or not!    The weather at Mount Gambier was absolutely perfect for the running of this annual event.   Blue skies with no wind (or flies).   The Atujara contingent was a little down for this year with Malcolm and Wanda getting ready to go back home to New Zealand and others just too young to attend for the over 45 Senior’s meeting.

We still had a merry band of;
Graeme Wagland 250 MOV Velo (Bruce Pederick’s), Honda CB500, 650 Triton
Greg Summerton  super ace mechanic and gopher for all
Chris Pash  Team Mellow Yellow 500 Suzuki
Wally Ryan  250 Yamaha LC plumber’s water cooler special
Richard Metcalf 350 7R, and 500 Manx

Graeme didn’t think he would have time to ride the sidecar as well, so left that home.     Bruce Pederick assisted with as mechanic.

Ex Club Member Gary Kerr turned up to watch Brother Steve race and to assist Richard as well as continue stirring me!   Gary has bought Chris Newsome’s two Suzuki’s and is returning to racing after 25 years in retirement.

The racing over the two days was serious and fun, which goes to prove that the oldies never grow up.  It’s amazing in the “age” group racing how close a lot of the competition is irrespective whether they are riding modern machines or classics.   The age group racing are in the following format: 45 years to 54 years (now in three capacity classes as there are so many riders), 55 years to 59 years, and 60 years and over.

In addition to the age races, there were the usual capacity classes as well as the famous “Cup” races.   The Cup races have been extended this year as the rider’s and machines are getting older.  The idea is to add the rider’s age to the machine’s age to qualify for these Cups.   This year, they ran; 45+ year cup, 65+ year cup, 90+ year cup, 100+ year cup, and for the first time – 110 year cup.   All were very seriously contested.

The final results were:
Period 4 250cc   Wally Ryan 1st
Period 4 500cc   Chris Pash 1st , 2nd Graeme Wagland
Period 3 500cc   Richard Metcalf 2nd, Graeme Wagland 8th
Period 3 350cc   Richard Metcalf 1st
Koggs Keogh Award  Richard Metcalf 1st
45+ year Cup up to 500cc Chris Pash 5th, Wally Ryan 6th

65+ year Cup   Wally Ryan 15th, Chris Pash 16th
90+ year Cup   Graeme Wagland 7th
100 year Cup   Richard Metcalf 1st, Graeme Wagland 5th
110 year Cup   Richard Metcalf 2nd, Graeme Wagland 5th

Richard’s race of the weekend was the 110 year cup and he rode his heart out on the trusty 7R to harass John Maher on his 700cc Manx for the entire race, but the poor little 7R just didn’t have the legs to pass John and hold him off.

Of course we have to thank Joe and Thelma Ryan again for there on-going support.

The ESO Road Racers

Wednesday, May 16th, 2007

Jaroslav Simandl was the owner of a small engineering firm in post war Czechoslovakia, he was also a speedway rider, so naturally enough he found himself making replacement parts for his JAP powered machine because foreign currency was not available in the Eastern bloc to enable import of much needed spares. He was soon supplying other riders
with them.

By 1949 he was making complete replica JAP speedway machines, soon with “ESO” (Czecho for “Ace”) on rocker box and tank. (Although “JAP” was still on the cover at the bottom of the timing side crankcase)

In 1950 his son Jiri took up road racing so they built several machines using their JAPclone engines, 4 speed boxes and telescopic-forks. They also used their own twin loop swingarm frame, proving that it was not only the McCandless brothers who were looking to improve handling with better frames. In fact, Simandl made the move before Nortons
did.

So successful were the ESO/JAP speedway engines, and the 5 road racers, that a new factory was soon established in Divisov.

During 1953 they released the short stroke 88mm x 82mm S45, the first fully ESO designed engine. (Later rebadged as JAWA) So well designed and conceived was this engine that the improvements and changes over its 30+ year production life were minor. The only major reliability improvement was to the crankpin in about 1966, it changed from a nutted taper to a stepped parallel press fit construction. Similarly, all other improvements were “add-ins”.

They simply got this engine brilliantly ‘right’ … from the beginning!

In 1953-54 several of these engines were put into factory road racers, again using the separate ESO gearbox. Their 42bhp @ 7,500 rpm on petrol was the same as the Goldie achieved a few years later. Again, these bikes had a twin loop frame closely resembling the Featherbed that had just appeared in Britain, but now a trailing link front suspension and a 230mm SLS full width brake graced the front. This, with a 200mm hub on the rear meant that it stopped well, something only the Italians had woken up to by then.

What a pity those eastern bloc low budget factories found it impossible to compete on the world stage. However, the new ESO pushrod singles beat the entire works road race team with their Jawa DOHC 500 twins at the Czech championships in ’54

But just when things were looking rosy the ‘government’ got in the way, as they had a habit of doing in Eastern Europe back then. The speedway engines had become so successful that Simandl’s company was ordered to concentrate on speedway machines and to leave the road racing to Jawa, who already had world recognition in this class.

However, against the odds Simandl continued with the road racing development and by the end of 1954 he and his chief designer Jaroslav Cervinka had designed and produced a unit construction wet sumped engine that owed little to the speedway engine apart from the cylinder had and cylinder castings.

But the works Jawa DOHC twin had been redesigned by now and had found more speed and reliability, so perhaps the new engine was not quite the step they really needed?

So only eight 500s and five 350s were produced and successful as they were, these engines went on to be developed into the 1955 ESO motocross machines because Simandl now had other plans…

By 1957 they had an exciting DOHC 4 valve 5 speed unit construction model that produced 52hp at 9500rpm, which would have seen it quite competitive with the Manx at that time. Unfortunately they did not race it outside Czechoslovakia, so intent were they on producing the speedway engine and so doubtful that they could ever capitalize on it.

By 1966 the ‘government’ announced that the ESO speedway machines would henceforth be known and marketed as JAWA. The Jawa marque was by now well established in the west, it made no commercial sense to start and fund new distribution channels and dealerships so the companies were to merge, although the bikes were still made in the ESO factory. If you look under the skirt of every 2 valve Jawa piston you will find ”ESO”….and until the early 70s the ESO logo continued to bracket the engine numbers on Jawa crankcases.

In the late 70s, when the 2 valve ESO/Jawa’s reign was coming to the end with the appearance of 4 valve rivals, they turned again to Cervinka to design their own 4 valve machine, and that went on to win countless national and world titles, as had its 2 valve predecessor.

That success makes one wonder, what if Simandl had been allowed to continue with the Cervinka-designed 1957 unit 4 valve 5 speed DOHC road racing machines……… ?

One of the original 1950 bikes, a pre-unit S45 model and several unit machines are still raced in Europe, In addition there have been numerous speedway-engined road race specials built and raced the world over since the mid 50s…..and for those who think that there were no ESO specials raced here in Australia in the pre-1963 period, think again……both an AJS 7R-framed ESO raced in Tasmania and another ESO special raced in NSW in the early 60s.

Oh, and if you check out the timing side cover of all the pre-68 ESO/Jawa speedway engines you will note that the boss on which the rectangular-ish oil pump is mounted is round, to suit the round recirculating gear pumps that the factory road racers used. These engines still carried their joint road-racing heritage with them.

When you consider that specials formed the background of racing here in Australia during the 50s and for most of the 60s, the ESO specials certainly have a rightful place in the racing history and race tracks of Australia.

Bathurst

Thursday, February 4th, 1999

In 1931 the races were held at Vail Circuit, on the other side of Bathurst. It was twice as long as the mountain circuit is today. The Mayor of Bathurst, Alderman Martin Griffin, was a keen motorcyclist in his younger days. In 1935 he had a scheme to build a scenic drive on Bald Hill and a magnificent race track, providing work for the unemployed following the depression and at no cost to the council.

He approached the Federal Minister for Works for a grant for the scenic drive, but did not mention the race track. In 1936 the council was offered an initial grant of 7,000 pounds toward the construction of Mount Panorama Tourist and Scenic Road.

In 1937 council wrote to the ACU asking for an offer to be submitted for the use of the “scenic road” as a race track for the 150 Centenary Races in 1938. It became obvious the track could not be sealed in time for the Easter Races in 1938 so they went ahead on a granite base road. 18,000 spectators rolled up to see the mayor drop the flag to start the first race on the Mount Panorama circuit.

On December 28th 1938 the last workman walked off the last section of road tarred and sealed, after two years at a cost of just under 27,963 pounds, 3 shillings and 4 pence.

Bill Mitchell has a map of the Vail Circuit and also a 1938 program. I rode at Bathurst in 1970, 1971 and 1972. In 1972, when the Australian TT was held there, there were 210 solos and 46 sidecars.

The race between Bill Horsman and “Ginger” Molloy (NZ) was the best in years. Ginger was faster on the straight but Bill was faster over the top of the mountain. Some say he was the fastest ever. Bill went under him on the last bend to win.

“Could we put a scenic road at ACUSA Park?”

How It All Began

Thursday, August 6th, 1998

It seems it has become customary for the venerable and respected elder statesman of our club to indulge in a nostalgic look at the history and heritage of times long gone, and our worthy editor has suggested that I might like to add a comment or three.
However, given the constraints and limitations imposed by senile decay and riotous living, my first reaction was that such an assignment would be completely nullified by a total lack of journalistic talent. And besides, too much water had passed under the bridge anyway.

Looking back through the dimly lit Tunnel of Time that has made up my 85-odd years, I realise that just over 70 of those years have been spent in pursuit of motorcycling lunacy of various kinds. So many people, so many bikes, so many changes! To give you even a brief outline of all those years would make rather a bulky newlstter. So instead of boring you to tears with the big picture, I’ll instead bore you with the little picture. I’ll tell you how it all began…..

As long as I can remember I’ve had a passion for mechanical things, particularly mechanical things with two wheels. Back in 1927, during my last year at Aldgate primary school (14 was the usual school-leaving age in those days) a classmate of mine had an uncle who lived at Blackwood. This uncle had a son about our age, and my mate and I would sometimes catch a train to Blackwood and visit, getting up to the usual misdemeanors perpetrated by schoolboys at that time.

But what interested me most at that time was that in the corner of his garage stood the skeletal remains of what was once a 350cc oil-cooled Bradshaw motorcycle. Sure it had no engine. But that didn’t bother me. It had two wheels!!!

After a considerable amount of pestering, the old boy said that if I “took up” the big ends on his old Overland car, I could have the derelict in the corner. I hesitated not a second, and eagerly leapt at the offer, despite the fact that I didn’ t quite know what the big ends were, or where they were, or how to “take them up” if I could locate them.

Nothing daunted, some discreet enquiries among my more knowledgeable aquaintences gave a bit of an inkling, so armed with some borrowed tools and a feeling that fools rush in where angels fear to tread, I spent a whole weekend lying on my back in the dirt of his garage floor in complete and utter bewilderment.

No point going into details — let’s just draw a curtain over this particular episode in my life. The main thing was — I had aquired my first motorcycle!

Pushing it from Blackwood to Aldgate made climbing Mt. Everest seem like a Sunday morning jaunt. The next month or so was spent just looking at it, and vainly trying to find an engine that would somehow fit between the road and the lower tank rail. Finall y, in despair, I asked about the original engine, and was told that a monumental blow-up had destroyed most of the internals. The lot had been junked in one of the local dumps.

I shudder to think of the tons of foul smelling rubbish that was raked over during the next few weekends, but perserverance brings it’s own reward. The remains of the engine were indeed a sad site, with ample evidence that destructive forces had been at w ork. Much time was spent scrounging bits and pieces that looked even remotely like they could be made to do, and a good deal of blacksmithing was required to knock things into shape. Finally, towards the end of 1928, came the moment of truth.

O Hallowed Day!
 
Mind you, the thing was fairly basic. Frame, engine, gearbox, petrol tank, somewhere to put your bum, feet and hands, and — two wheels! At this stage there wasn’t even a hint of an exhaust pipe. But, it was ready to roll!

After much pushing up and down the road to accompanying phuts, splutters, pops and bangs, it was finally proceeding under its’ own power. Perhaps “power” isn’t quite the right word here.

Maximum speed seemed to be about 131/2 miles per hour, give or take a few. The exhaust note emanating from the hole in the cylinder head wasn’t quite up to my expectations of what a well-tuned engine should sound like. “The t imeing seems late” said my know-all neighbour. Asked me how I’d timed it. So I told him. Wait until the piston has started to move down a tad. Then light the match. Wrong, he said. The spark should occur before the piston reaches the top.

I wouldn’t have a bar of it. The man’s crazy. Anyone knows that if the spark occurs before the piston reaches the top it will only push it back again. Maybe I should have apologised to him later on, but I didn’t.

Over the next fwe months the old Bradshaw was to undergo an almost incredible metamorphosis. This was entirely due to the fact that at about this time I got to know a chap who had a most profound influence on my whole attitude to motorcycling. His name wa s Steve Hocking. His expect knowledge and practical assistance resulted in wringing the sort of performance from the old Bradshaw that the designer, I’m sure, never intended.

Around this time Steve formed the first motorcycle club in the hills, the Mt. Lofty Motor Cycle Club, and I joined at the inaugural meeting. In March 1929 the club held its first competition – a closed hill climb, and I somehow managed to win the 350 clas s. Later that year I turned 16 years of age, and got a competition licence. I rode in my first open competition in November that year (1929) in a scramble organised by the Harley Club, run on a circuit at Marino Rocks. Another young chap having his first ride at that meeting on a 23/3 hp New Hudson was later to become a well known Atujara member — the late and great Laurie Boulter.

Over the next few years I rode the wheels off the faithful old Bradshaw, both as an everyday road bike and as an entrant in most of the competitive events around at the time.

A vivid recollection of those years is the difficulty I experienced tempering my youthful exuberance, resulting in numerous unscheduled excursions into the roadside shrubbery.
 
As the mid-thirties approached I had outgrown the old Bradshaw, and bought a secondhand Mark 1 KTT Velocette, a make I had long admired. The idea was to ride in the Centennial T.T. due to be held at the end of December 1936, but a fractured scaphoid susta ined in a scramble spill a few weeksprior meant that the role of spectator was the next best thing. I had to wait until the Australian T.T. at Lobethal in 1937 before I had my first taste of what motorcycle sport is all about — road racing. It was the start of a lifelong passion.

I competed at Lobethal in ’37, ’38 and ’39 with the only result worth mentioning was a 4th place behind Doug Booth (W.A.), Frank Pratt (Vic.) and Harry Hinton (N.S.W.).

The end of the 1930′s saw two significant milestones for me. Firstly, I sold my Mark 1 KTT, and bought another Velocette, a KTT Mark IV. This machine was one of a small number of secondhand racing bikes imported by Paddy Read of Universal Motors, and the KTT had won the prestigious Hutchinson 100 race at Brooklands (England) a few year previously, ridden by the late Noel Pope.

Secondly, about this time I joined the Atujara Motor Cycle Club. The future was looking pretty bright. But the good times were not to be. By then the second World War was getting under way, and that stuffed up a lot of things. The Army commandeered many o f our bikes for military use, petrol was strictly rationed, and motor sport was banned for the duration. What I didn’t know was at the time, however, was that I still had nearly 60 years of active competition riding ahead of me.

Maybe one day I might tell you something about some of those years…..

The Way it Used to Be – or Woz!

Monday, January 5th, 1998

Following the second world war, 1939-45, motorcycle racing recommenced in S.A. with most riders competing on their road machines. After riding to the track, the lights, number plates and etc., were removed, events were ridden then the lights and plates went back on and home they went.
In speedway racing a lot of riders started riding older machines. For example, Jack Young, who went on to become world champion, used to ride a Peashooter Harley as did his brother Joe while another brother, Frank, rode a Norton. Several other riders, most of whom lived in the Flinders Park-Findon area, including Bob (Bakey) Leverenz, rode a variety of machines that were adapted to speedway style. After a few years several JAP pure speedway machines came on the scene so a road class was incorporated in speedway racing. This class continued for a few years until eventually there were enough pure speedway machines to run meetings. So, out went the road class. Some of these riders gained sponsorship but, other than those lucky few, if you couldn”t afford a tracker that was the end of your speedway career.

Riders then began riding road machines in scrambles or motocross as it is now known. Riders competed on BSA, Matchless, AJS, Tribsa”s, after a few years along came the Greeves, Dot, CZs and other special motocross machines so if you couldn”t afford one you were no longer competitive. Probably a lot of riders retired before they wanted to.

Observed trials riders competed on converted Villiers, BSA Bantams and any other small machines they could adapt. There was the occasional four stroke competing. Probably the most notable was our club”s Fred Greneklee on his 350cc AJS. Most of these riders were able to enjoy their trials at a reasonable cost.

Eventually along came the Bultaco, Montessa and other well sprung motorcycles which eventually made the Villiers specials pretty well obsolete. A lot of riders still competed but with no Bultaco or Montessa no good results were obtained. So unless you could afford good machines you were out of this branch of the sport.

To their credit the observed trials clubs decided to run a greybeards section and a few older members dragged out the old Villiers Specials just to have a ride. Eventually the sections became so tough that no riders on these old machines were able to complete the course. So although there is still a greybeards class, unless your machine is fairly up to date you”re only in the trial for a ride, which is probably what most motorcyclists care about anyway.

In the period 1945-1955 most people in road racing competed on road registrable motorcycles that were in various stages of tune. There were a handful of Manx Nortons, Gold Stars, 7R Ajays, competition AJS/Matchlesses, Triumphs and etc., and the hand built Velos. The most famous of these being the ELDEE Special built by the late Les Diener.

Road racing fell into a bit of a slump for a while but it was only temporary and this seems to be one section of our sport which has not been affected by the almighty dollar, mainly because of the introduction of Classic and Post-Classic classes etc. Not that I think that competing in these sections wouldn”t cost and arm and a leg anyway.

So, by reading this article you should be able to realise that each section of the sport of motorcycling has been taken over by people who have been perhaps able to afford or have been good enough riders to gain sponsorship to have superior motorcycles to ride, the lucky B ….. s!

Bill Horsman Wins Junior Classic Manx Grand Prix, Isle of Man 1997

Sunday, January 4th, 1998

Club Member, Bill Horsman has again flown the Atujara flag at the Isle of Man Manx Grand Prix with a win in the Junior Classic and a fourth place in the Senior Classic. The Junior Classic was held over 3 laps (instead of 4) on Wednesday 27th after a delay due to extreme wind and rain all morning. Bill, riding a 349 AERMACCHI won with an average speed of 99.20 mph in a time of 1:08:27.3

The Senior Classic was held over 4 laps on Monday, 25th August in perfect conditions (18° C). Bill placed fourth after Heath, Jackson and Swallow on a 499 MOLNAR NORTON with an average speed of 103.32 mph in a time of 1:27:38.4
