Eligilibty scrutineer at the Nationals

[Hornet]

Me running an illegal bike ? I can not even master the stock  peak power it hade . I just run for fun and atmosphere, but the atmoshere has to be good , thats all . I just can not understand the seriosness of some people argumenting about about the size of a hub or if the sprocket is welded , riveted or boltet to the hub . Any bike in the spirit of the era should be welcome and not torn to pieces. Thats all I wanted to say . Sorry for dropping in

I agree with you there about all the bullshit about eligilibity. Thats why i moved to evo class years ago.. less crap and less whining!

David,
        Your remark about the Bultaco Mk7 & Mk8 250 as far as eligibility goes, they are the same bike. As long as the swingarm from a Mk 7 (4'' travel) and spacers are put in the forks (to make 7'' travel) The engine internals and barrel are the same.I raced mine at the 07 nats and had no problems and I am sure that there will be some at the 09 nats. Its the 360 Mk8 that is ineligible because the engine had a major power increase over the Mk7.
  Comments Please.

So Mk8 250 engine numbers wont present a problem re pre 75 eligibility?
Whats different in the Mk8 360 engine?

  The Mk7 360 (M121,eligible pre 75 open) was actually a 352cc engine. The new Mk8 (M136) engine had a wider barrel stud spacing,bigger transfer area in the crankcases and cylinder,it was a 363cc engine.
    It has been deemed to be a major power improvement from the MK7 engine and does not qualify as a carry on model,therefore pre 78.
The frame on both models (7and8) is essentially the same,the Mk7 had a machined steering head and the MK8 a pressed steering head.The footpeg mounts were slightly different in the way they were welded to the frame.The swingarm was different on the MK8 to allow more travel and the forks were longer,from memory they had 8 1/2" at the front and 6" at the rear.Both easily changed back to 7" and 4".
    All Mk8 engines have the ability to have either a left or right hand side gear change.
 To allow this it had a rear wheel that allowed the brake/sprocket to be on either side.
    As to your question about MK8 250(M135)engines. The Mk8 250 uses the same cylinder as the Mk 6 and Mk7 engine,Cylinder 103.As to it being eligible at the QLD Nats,I think that to be sure it would be best answered by Dave Tanner.

Without getting shot down again , who is Dave Tanner ? Is he the man making the rules for VMX bikes?

[bazza]

Thank you

I was told  that Micks suzuki was a 75 model not 74

I've stayed out of this up until now because in my mind it was old news and little could be gained by reopening old wounds. However, Mick Cram is the bloke who was also affected by Allbrids disqualification and I think his rep has been tarnished as well as Daves over the years through no fault of his own.
You couldn't meet a nicer bloke than Mick Cram. He's rarely missed a vintage meeting in over 20 years even though he's not exactly being the fastest bloke on the track. He was there at Amaroo Park in 1988 at Penrith Clubs very first vintage meeting and is still coming along despite not being in the best of health. He just loves being a part of the sport and he and his old mate Jens Olsen and their ugly Suzukis have travelled to all corners of the country to race and I'll bet they'll be at Conondale.
I'm pretty sure that after Allbrid handed back his trophy, the accusations started that Crammys TM125 was also illegal. In fact it had passed in scrutineering and was again later proved to be a legitimate 1974 TM 125 model. The bike had a sunburst 1975 tank fitted at the time which is probably what caused the confusion that sticks to this day.

[Hornet]

Now I have to ask another stupid question . What makes a 75 tank on a 74 illegal ? I am not a blonde , but I just dont get it .

[Oggy Doggy]

What makes a 75 tank on a 74 illegal

It doesn't. The accusations were that the bike was a 1975 model when in fact it wasn't, it only had the tank which caused some to think it was a 75 model.

Me Too!, Im gunna make all my bikes "Illegal" so I don't get to go and therefore don't have to put up with the pathetic bullshit that goes on with the 75 model bolt in the '74 model bike bullshit bullshit.

Meh. Its pretty easy to sort this shit out if you want to sort it out, especaily nowdays when everyone has a chance to have their say via the internet - the truth will come out, and usually quickly. Also worth noting that several people have described that particular year's Nats as being less than wonderful - I'm sure that the Qld people will be very careful to avoid anything similar putting a cloud over their event. In fact, starting this thread was specifically designed to minimise those issues....

Dave Tanner is also a VMX Commissioner for MA, so as well as a better-than-average understanding of stuff, he also has louder-than-usual say in the rules.
