Hey guys, I just got my 450R. I'm getting the HRC cam, WB Aluminum Race pipe and K&N........my guestion is, what size jets should I use? Thanks for your help.

for the amount of money you paid for that pipe you should ask white brothers,they should be the best to answer that .

I haven't bought the pipe yet......is it not a good choice. I'm going to be riding in the sand about 90% of the time. What would be the best pipe then?

Thump it, several guys who I have talked to and ride the oregon dunes love the Yoshi. It puts out great power and isnt as loud as Sparks or Lrd. I havent heard anything about WB so I couldnt tell ya if their good or not. Call some of the local builders and see what they say.
