Does anyone know what RPM numbers the stock clutch and torque springs are on a 90cc DRR?Ours where all red.Torque spring went bad and Sondre blew the belt,replaced it with a 1500rpm ZTR spring,it felt a bit softer but seams to work fine.Any ideas ?

1500 ZTR is what we replaced our stock spring with and now several springs later all is good.

i would consider putting some snow hogs, razr cross or the new DWT Jr tires on the rear to save some weight back there. The stockers are too wide.
We got a set of the new DWT's and they are absolutely unbelievable on traction and light weight.

I just put on Maxxis M 940 on the back they work great but the new DTW tires looks nice to.:D (no clutch issues on the 100cc Apex with these tires.)
