I am new to this forum so please bear with me. Just for some backround, I have a 01 I purchaced in april it had a amazing 2100 miles on it when i bought i have about 5100 on it now. I have since lowered the front 1in. and the rear about 3in. I have put the brocks clutch mod and clutch coushion along with the heavy springs and the new wheel adjuster on the clutch lever. Oh it had v&h slip ons when I bought it. I do try to drag race every friday nite. The mods I did to the clutch did really help with controling the clutch when launching. So the question i have is if i am riding on the street or parking lot at a lo speed in first or second gear say idiling or up to say 2000rpm the thing jerks terrable it is bad enough you have to pull in the clutch and kinda start over. I dont mean stop or anything like that just give it a little gas and let the clutch out again. It will not do this if it is under power at all. It also did this before the clutch mods. The only thing I can think of is the cushions in the rear wheel. If anyone has any ideas please let me know. Thanks in advance. Oh by the way i pretty well suck at drag racing so far. Best run so far is 10.25 at 137mph with a 1.7 60ft. I wont even tell you the rt.
