I have 2002 raptor 660 that is stock. I have a 12 tooth sprocket for the front and a stock size sprocket for the rear. my goal was for increase tourqe for trails and hills. I do have 22 n itp tires in the rear with 21 tires in the front. Was wondering what would be the best chain for me did xring or oring chain or any other brands. Also i was think of buying a clutch for the bike but was unsure of what brand or what to go with. Any help would be great. I have about a 150 to drop down. I think my clutch is still ok but was thinking of just redoing as the bike as been riden by the previous owner. If i should not do thaty what should i do. thanks again

 

If you are going to be riding through some mucky stuff the x-ring should provide the best protection. 12/40 is a good gearing setup but if you have room you might want a 12/42.

As for the clutch, go with the gytr set and install the stiffer springs.
