Hey guys,

I have a timing advance, Rev box... going to be getting a powerlid (where do they sell them???) and (do they come with the KN power kit??? w the dyno jets??) and im also going to be removing the spark arrestor... any recommendations on jetting???

PS - Ive never jetted before at all.. dont even know where they are actually???

thanks,
Dustin

also - Any tutorials around on how to jet a 400ex??:confused:

the lid comes with a cupple jets but on r rapter all it did is make it foul plugs.
