I have the same kit on my wifes machine. I really like the bottom end power now. However, the silencer did break on a factory weld. I just welded it myself. Scooter, did you like the speed the 12 tooth sprocket gave you? I was thinking of doing the same thing. The quad has enough bottom end, I am just looking for a little more wheel speed for the dunes. Oh ya, I can wheelie this thing with no problem.

 

Stickhauler, I put the new 12 tooth, 42 tooth rear and new chain on when I noticed the weld had broke. I have had the pipe re-welded but haven't had it out to test it yet. Hopefully I'll be out next weekend to check out the difference.
