06 450er rebuild question

[hondarider16 69]

im thinking about rebuilding my quad soon and if i put a 13.5:1 comp piston and a cam can i still run 93 pump gas in it or do i hav to run higher octain? it has a motoworks slip on, a quadworks air filter, and dinojet kit everything else is stock

with 13.5 you should run at least 50/50

I ran all c-12 but I think I could have gotten away with a mix, but I didnt want to risk it

definitely won't be able to run pump, you can go all the way up to 12.5:1 and still run pump.

ik many people who run pump on 13.5 and have no prob just keep up on regular maintance adjust valves ever 5 hours and piston every 20

i agree i run straight 110 through mine with a 14:1 and I dont touch the piston all season.

there are alot of people that say you can get away with 13:1+ compression on pump gas since the whole engine is aluminum and transfers heat well, but it really isnt worth the risk of detonation. it doesnt take much for it to break a piston/rod and take the cylinder with it. a mix of c12 or equal and 93 octane will be fine.
