Thanks Woody.G

Good advice chaps, I'm just a bit careful having raced 2 stokes in the 90's and recked hell. out of how knows how many engines when ACU ruled unleaded only[ TZ350 on TESCO unlead..[Oh please] . AVGAS never gave any extra power on the Dyno, just better "pickup", burns slower so better for the port timeing....Im over thinking this thing ?????

OK I'm going to say it..AVGAS. Dirty word I know and I know Im doing a Clarkson and destroying the planet but a little bedtime reading of the ACU regs says its legal for competition? It's been 35 years since I ran 2 stokes and assume I can run a 75 250 on it {what mix are you using?]. Avgas 100LL is basically the old 5 star back in the 70's . Discuss Graham

Thanks Woody, Been 35 years since I messed around with a "ring a ding" { 2 stroke}. lots of stupid questions to be answered!!! looking forward to some fun days out and not to many engine strips!! Graham

OK, 75 bike but still not sure on the engine, ACU now allow AVGAS ? what is the mix going to be?

many thanks

Just to say Hi....just delivered yesterday is my 250 Sherpa. had a Miller High boy 250 back in the 90's and sold it to fund my road racing. bad move!! Anyhoo, Iv got a frame number PM 15000445 and engine B 8002817, any ideas on the year and model?

Sorry to jump in, just bought a Bultaco 250. Do you know the mix please?
