well i have a 00 400ex with k&n air filter with lid on, scorpian slip on exhaust, hot cam stg2, and a .040 over kit (402). i am gettting ready to get it all togeather and im not sure which jets to get. any help would be appreciated!!!!!!!!!!!

 

fmf or k&n, not sure about dynojet. i have a fmf and it rocks.

 

hey and i also see that yougot your piston and everything.( this is the guy from lynden right?)

 

a pipe and bore and all that i would go with at least a 160 main, 40? pilot i belive? but double check, and it depends on where u live alttiude and such, every engine behaves a little diff but id start with 160 main

 

ok thanks, i am in louisana so im at sea level
