how many teeth should my front and rear sprockets have that would be best for motocross with a raptor. also does any one have or heard the lrd pipe . how is power and sound output on it. thanks

 

Hey Loudpipes, I got the LRD pipe on my Raptor and it really made a big different then I used to have WB E-series pipe. That thing rock. It got a hard pull on 2nd and 3rd gear. It really take off in a heartbeat. Also I have the dynojet kit that made for LRD pipe only. The sound is not too bad and at least it quite lower then WB E-series pipe by far. LRD have update their pipe by putting cermiac coating and different cansiter on the pipe. It look pretty cool.

For the sprocket size I would have no idea for the MX since I do desert racing and duning. I run 14f and 40r.

If you got any more ? of LRD please ask.

In my opinion it is a good investment for the pipe. You won't be disappointed at all.
