    What kind of fuel

    Hey guy's I am almost done putting my 01 GP1200R together. It has a skat pump and prop, advert ecu, triples, NOVI carbs, m-16 reeds, riva intake manifold with boost bottle, and pro-tec head with 37cc domes. My question is what octane would you suggest for closed course racing.

    Depends on the ignition curve. I run a very similar setup with the Yam-61 curve and use a 93, 110 octane mixture. 3 gal 110 and 2 gal 93. Average out to around 100 octane.

    Last year was 80-81. New numbers this year though. I upgraded to skat setback pump and am getting a crack I found in one of my triples fixed. As well as some hull work and motor porting. So hopefully this year I will see 85ish and arm wrenching acceleration.

    watch what octane you mix together and do some testing. higher octane doesn't always give you positive results. find the right combonation that work best with your ski. and don't forget...every ski is different

    The lead content is the key.... A 3 to 2 mixuture would be safer than what I run. Dont know what my domes are but compression is higher than yur average monkey{160+}. I just burned 20 gallons 4-1mix 112 octane 36:1 oil mix. No probs! If ya over octane though it will slow down
