superchicken Posted March 31, 2005 Report Posted March 31, 2005 if you didnt rejet the carb after the pipe and filter ya have to now.go down 1 clip on the needle and have no idea what size main cuz i dont know whats in them stock Quote
Brian060 Posted March 31, 2005 Report Posted March 31, 2005 that happend to mine. Probably the clutch is fried. Quote
demonspeeding42069 Posted March 31, 2005 Author Report Posted March 31, 2005 its not the clutch ... it shifts and everything fine..... its hard to explain its like it has more power now but its not using it dont know how to better explain it .... im sure it just needs some tweaking and adjust ment some where... mainly carbs i think .. as for the main ...i dont know the size either but generally speeaking would u go bigger or smaller main with those mods???

ssanddemon Posted March 31, 2005 Report Posted March 31, 2005 I'd try like 3 sizes up on the main, maybe buy a couple more in the upper and lower sizes around there, most bike shops let you return the unused ones if they're in good shape. But yes, the (auto) clutch may not be holding as well. Quote
rocketboy Posted March 31, 2005 Report Posted March 31, 2005 a word of caution those bikes have garbage valve seals and valve guides , they are not very good on topends for a 4 stroke even ones in good shape . your current problem sounds like your runnin lean and need to drop the needle clip position,4 strokes are funny like that, a clip position will make all the difference versus a she where you might go 10 sizes up on a main after a pipe and filter kit!

demonspeeding42069 Posted March 31, 2005 Author Report Posted March 31, 2005 thanks guys..... ya it ran absolutley perfect before ..its like brand new, (it got my ass up the hill at silver lake sand dunes no problem and i weigh like 215 lbs , i think its a pretty good machine (for a gurl starting out ) and paying only $800 for it then when i put the mods on it all changed so i know its just a small matter of fine tuning ... but wil try moving the clip down see if that does it . thanks again rick Quote
