WR400 pipe on YZ426

1 post in this topic

I've temporarily put a WR400 pipe on my YZ426 for those occasions when I want to ride with trail or dual sport guys and not sonically offend all of humanity within 1 km. My question is: should I lean out the jetting (or how much?) to compensate for the extra back pressure from the pipe? Has anybody done something similar before?
