Hey guys,
I'm pretty new to drag racing and am trying to improve my launching skills. I finally installed the welded clutch hub mod (big thanks to Heads Up Performance) and got out to Sac Raceway to bench test it against my previous times. I was pleased with how much more control I have of the bike now that the back torque-limiter isn't bogging the motor or throwing the front end up in the air anymore, however i have noticed one new nuisance that has popped up since the install. When I dump the clutch from a stop, the clutch seems to slip a few revolutions before grabbing and finally pulling the bike forward instead of the out-of-the-hole thrust I experienced before the clutch mod. I first guess is that the stock clutch springs aren't up to the task now, however when the bike was on the dyno, we tested the clutch under load, and there was no slip (while rolling). So the springs are holding while the clutch is engaged. I'm wondering if anyone has any suggestions about this before I run out and buy heavier clutch springs.
thanks,
Dave
