Will I get my 100 ready in time for Taupo?

Wonder why competition motors were excluded then. Has it always been 125 two strokes, or was it blanket 100cc whether air or water cooled?

The original rules were no competition (I think they used the words factory hot up parts) they specified cams and pistons etc
103 or there about cc 2 stroke
130.5cc four strokes.
100cc four stroke forced induction
100cc four stroke open fuel. i think it was only avgas or methanol though.

Cheers for that.

Cheers for that.

I have been trying to find the original small coloured books I used to have a few.
They were ACU books .

Air force boys bringing back Asian racekit parts for A100s and the like obsoleted std ones.
Don't remember open fuel. We were on pump gas in the late 80s when I started.

100cc four stroke forced induction and methanol, now we could do something interesting with that.

Brand new A100 race kit cylinders were available from Suzuki NZ in early '80s for $15ea. We bought all 5 that they had and it wasn't the Air Force guys. Yeah pump gas at the start though a few were scoring 100 octane as one of the large aviation companies used to leave it lying around and you could help yourself, evidently

Me and an Army mate scored a fully race kitted A100 for $50. I got the 18" wheels and he grabbed the motor.

I am not sure if it was. It was a long time ago now, probably 25 years ago. I think it might have been an either or situation,(only four 100cc 4t) but maybe Grumph or Mike G can remember.

[speedpro]

....or Mike G can remember.

Me remember? what were we talking about again?

[husaberg]

Me remember? what were we talking about again?

Whether the 4t 100cc were allowed methanol and other open fuels and supercharger/turbo or it was an open fuel or forced induction in the old original rules.

This is the wrong thread for fuel discussion, it's all about dave and what he's done wrong....

However, as i remember it, everything was pump fuel - which was taken under the ACU regs of the time to include avgas...except supercharged fourstrokes which were limited to 100cc but could use open fuel. Pre '89 this would have included Nitro. The Methamol/Nitro option disappeared from buckets when it went from other classes too. I walked out of that years conference in protest....
Background - I'd been involved with the fastest F1 bike in NZ for 3 seasons using a meth/Toluene blend plus tony Mcmurdo's F3 and F2 bikes using the same blend plus big jolts of Nitro...I felt justifiably aggrieved that having out thought the opposition we were being banned.

Yeah but was that at the same time as the Robert Taylor TZ250 yam and BMS f1 framed 750 Ducati protest counter protest F2 saga.
I never knew the f3 GPZ500 was on the juice too though. I have that KB article somewhere with the write up on the F3 bike.

I'd be interest to learn a little more about the GPZ500... Have one in the shed and was thinking about what to do with it...

Grumph did it...........I bet his memory would be more actuate than any reporters blub
