do i change jets

[leakyvoodoo]

i blew up my bike last weekend at the track leaned it out. carb popped off. so bigger is better going with 426 13.1 i know i know need to run 110. my question is do i change my jets. i was running 180 and 48 i think. or keep them in and tune from there.

changing bore, stroke,compression, only has a small affect on the amount of air that will be pulled through the intake,

so only minor adjustments might be required,

its not as radical a difference as say changing the intake or exhaust,

what goes in and what goes out is a much bigger factor on jetting then internals do

and as far as fuel as long as your not running oxygenated fuel then it shouldn't make any difference either
