G'day Mark,

thanks for taking the time to enlighten me (and everyone else) on the SR60 and Meirson stories. its hard to imagine anyone taking on such a task these days. certainly an interesting peice of speedway and Aussie motorcycling history in general.

tell me, does Alan J have a DT500 douglas or rudge speedway engine in his collection ?

what a great read this topic has developed into! cheers wally.

No Alan none of that really early stuff but I doubt there's a Jawa conversion he doesn't own. How's a rare American Offenhauser bike solo engine grab you or a 4V Rickardson from Sweden. It's amazing just what he's got.
Below is Jonesys #1 of 4 made Weslake 4v twin cam 1000cc twin, shown in a Terry Mead made road race frame.

I have a soft spot for Wessy's ever since i saw Russell Bergmierer and Lester Trewin ride an 850cc twin Weslake MX Wasp Sidecar back in 79' at Wonthaggi ( Vic titles maybe) Russell used to over rev it in each gear and it was fine as it was an  engine developed for UK grass tracks. that made such an impression on me at the time i have never forgotten it and started my love for Sidecars and Speedway engines.

Russell and Lester purchased a 500cc twin Weslake ( probably the only one ever in Australia) to compete (and win) the 1982 Aussie MX 500cc sidecar titles at ACUSA park in S.A. and i made the trip over to watch those titles sleeping at the track.

i Also remember Sth Aussie Barry Buckley riding an XV1100 V Twin Yamaha side car at that same event. This was also the same event that Ray Vandenburg stuffed his knee ending what was the start of a  brilliant career.

for the life of me i cannot remember who won the following, can anyone fill in the gaps?

500cc solo ( Trevor Williams?)
250cc solo
125cc solo
Junior 125cc
1000cc Sidecar ( possibly Brian Stewart / Kim Demarte ?)

Here's a photo of the Meirson. It shows its JAP heritage but is a totally Aussie built item. I stated earlier that Alans engine (shown here) was brand new and unused but Alan informs me that it's seen action in a TQ midget. Also shown is the Rickson 4v from Sweden. They were made by Tony Rickardsons dad back in the early 70s but he sold off the rights to Briggo after a small number were made. The engine is shown as it was sent from Sweden, sitting in Alans new Monark GP replica motocrosser frame.

Here's a few more of AJs amazing collection.

Hi Guys,This has been a great thread,Here is a bit more ! This article was in the west wyalong paper in August 25 1972. Kev Beasley worked at our local Honda dealership,I always dropped in on my way home from school ('72 I was 13yrs ) and I remember Kev getting ready for the short circuit meeting the following weekend.He had just fitted the latest speedway motor to his hagon and the local paper took a photo in the Showroom, of him with his "Clarrie Meirs - Meirson MAGNUM" . Kev is now living in Brisbane and still racing speedway in the local area. PS I think this is one of Clarrie's first conversions as it has a different top end and running a magneto where Allan's motor is quite different. Cheers Len

 Hey 454 you mentioned the aussie made Hejisun, found a couple of shots taken in the pits at wagga by Graeme Wungluck .See if I can get them to post here !( bit of a novice on this yet ! )

[Grasy 6]

Hey Loop. (Godden79) are you going to bring the J.A.P. out of mothballs and throw a leg over it  for the Classic Titles.

[Godden79]

 Nah Grasy, the mothballs are too thick, it's still apart from when it was measured after the titles at Griffith in 98 ! Pretty slack eh. I'll just stick to watching you guys these days I think !!

[Curly3]

C'mon Len, I'm not going to beat around the bush here but I'm with Grasy, the Classic Dirt Track scene needs the profile that your involvement would help generate. If it's a competitive bike your after then just say the word and I'm pretty sure someone will come forward with an offer you can't refuse.
No horse heads involved I promise.
The Golden years of Dirt Track are in my "Blood", as it is with you and having someone who has been there and done it, certainly adds plenty of weight.
I'm personally working on brother Carl and I know the competitive instinct goes deep, but as I've already said, we would all enjoy you're participation.
Steve.

G'day all

Lenny , It would be awesome for every body for you to  come out an have a skid around  , not wanting to put pressure on you , mind !!
 Seriously, it would be a blast to see you out there, bloke , so I can go off  on the microphone.

Ta for posting the the pix of the Hejisun, Lenny,  now thats a rare one !!

What a thread this is and I think it's not over yet.

Steve, I pick up the copies of the video , on DVD , on Thursday will post it the same day, me and Tony Day # 455 ,watched it right through yesterday , what  a ship load of memories. some of today's petals should watch it to see what it was like back then, Cowra program Easter Sunday 1972, 7 heats of the 500 B, 18 riders a heat, only 2 make  it to the Semifinals, go hard or go home !!

Now comes the good bit. I tracked down Steve Anderson, #101 solo, #5 sidecar, and his dad Ray, ex showground sidecars in the era of Clacker Levy an Chook Hodgkiss, who made the original 8 mm and 16 mm Film and he still has them plus other stuff from that era and said I could borrow them to have them copied, am gunna see him at the end of the month
Will keep you posted

Hey Loop, the best thing about pulling the J.A.P. down for measuring in 1998 was to show that the rocketship was a genuine 500 & the rider/engine builder was the ticket. Aleast put it back together as a display bike at the Titles we could probably do it over a few beers.The Titles should be a great event for the year already 21 pre entries 5 in the Pre 75 slider class all that JAWA stuff. Cheers Grasman

 Going back a bit in this thread , I found the photo of the drive side of Jim Crowhurst's Hagon Kyokuto at Griffith , not much of a shot , but it's the only one of that bike that I have.
