Have a 2007 xr650L. bike was running great with power bomb header and Q4 tail pipe. Took snorkel off, new aftermarket air filter and was jetted with fmf kit to 55 pilot and 165 main. had new needle installed too, I think its 2nd or third down from the top ring. ran great, had no problems. just had honda install the hot cams stage 1 and it runs like shit. they brought the jetting down to 160 on the main but still has no power mid or top end. it just wants to fall on its face. pulled the sprak plug out, still dark, almost like a shiny black. Any thought or recommendations on where or what I should do with the jetting?
