Installed my new CVTech/STM combo tonight and it’s producing way more belt whine than I think it should. The whine is similar to the stock clutch whine in that it is consistent with the RPM’s. It differs in that it is a higher pitch and chirpy whine if that makes any sense. In neutral and park the noise isn’t bad at all even when you rev it. When you put it in gear and idle, it’s a little louder. The faster you go, the louder it gets. The STM comes with 6 fiber washers and I believe 3 of them are in the clutch (3 left in the bag). I’m running an OEM belt with about 200 miles on it. I inspected it on assembly and it looked good. The quad doesn’t move or "creep" in gear until 1700/1750 RPM’s. The good news is that the acceleration is MUCH improved!!!! I have a new found respect for the throttle and that’s all I’m going to say about that. Iv’e got to get this whine figured out though. Any ideas would be appreciated. Thanks!
