purchased the wife 03 trailboss and the clutching is way off secondary spring is to stiff for this machine i think it won't let it shift out properly so here's what i did put a red spring in 2-2 and a white primary with 10 M 5 weight WOW this thing rocks wheelies with out tugging on bars and pulls like mad and back shifts great any one else have any more in put thanks

 

Hello Tweeker, have you done any other mods besides the clutch? Hard for me to believe the thing rides wheelies with just the clutch mod since mine won't do it with everything I have done so far? Any help would be greatly appreciated!
