i have tried the 12,13 and the 14 tooth on the fr. but what about the rear ??? thanks!!!

 

If it is a 01 raptor 12/40 and 13/42 seem to be the most common.I switch back and forth from 12/40 and stock 13/40 depending on what type of riding.

 

It really depends on what your mods are, what type of riding you are wanting to do, tire size, etc... Maybe if you tell us more we can help you.

 

well 673, 11;1 hi comp piston, valves, hot cam stange 1, air box removed,dyno jet kit, and kn filter ,big gun slip-on.. w/20 gncc holeshots. thanks

 

forgot the port job .. all motor work was done by pr racing engines in ohio.

 

Stock back, down 1 in front.

 

Sorry, but with his mods you are totally wrong. He will be going through the gears in a heartbeat with a 12/40 combo out in open trails. For SLOW trail riding I would go with a 13/41 or 42 setup. For fast trails a 13/40 and for open fields or desert, 14/39 or even 14/38. Im running 14/40 and ride in the desert, I can go through the gears quickly and still have lots of room to give it hell. With a 14/3X you will have more top end speed and with your built motor you wont have a problem pulling that combination.

For reference, I weight 220 without gear and I can outrun my 160lb bro (velocyraptor) on his piped/jetted raptor with 13/40 and 22s. My bike is heavier than his and older too, but I have a very similar engine to yours.

 

thanks for all the help!!! i need to pick up a couple of rear spockets and ill try those combos out and let you guys know the results!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
