Domes and heads

[Root_Doc]

Obviously a newbie question. But with stock pistons and only t6s and vforceIII's, would 19mm domes and cool head give more power. Is it feasible? that is also with a 4+ timing. What is the purpose? Please help the dumbass

thanks

with smaller domes, compression goes up and depending on what dome u may need to change what fuel u use. I am making the switch to 100LL aviation gas with 18cc domes on a modquad head with stock pistons and jugs. I have almost the same mods as yourself and just want MORE!!

very nice looking bike man. ya more compression will give you more power. mostly on the low end. 19 cc would be pretty close to needing to start mixing in some race gas. generally the cutoff is around 150 ish. the more you advance timing the more likely you need some race gas as well. i would guess you would be ok to run 93 with 19cc and +4 but it also depends on elevation. you will definately want to check it and see before you run it a lot.

with the stock porting and the t-6's +4 advance iw ould HIGHLY recomend using a 104 to 110 oct fuel and re jetting for it. you do that and you will have a dependable bike. the stock porting will result in more compression.. ( lower exhaust height) and you should end up with a very strong midrange/ bottom end bike with those mods. if you want a top end screamer you would have to get a lil different pipe. BUT you will loose the bottom end that those t-6's have..

 

i have t-6's on my trail bike and i love them for that application..
