I put a 136 track on my sxr 600, now the sled seems to be alittle slow out of the hole, motor is running great, but clutching seems to be off, When throttle is punched from dead stop sled takes off but seems like it is in 2 high of gear or not enough rpms, then after about 25 feet it takes off like crazey, do I need rivits changed or spring?? it has stock clutching specs.

LIFE MEMBER ONLY ONCE!!!
we need to know what your peak rpm is and what you have setup for clutching.I am sure you have geared down some also...
