Jetting for 2001 YZ426F w/PowerCore 4

2 posts in this topic

I have the above listed bike running a Rekluse. I am having stalling issues leading me to believe my pilot is a little lean. Currently I have a 42 pilot, which I believe is stock. My guess is that the first owner did not jet when he installed the pipe. I ride from 2,000-7,500 feet, mostly trails. What jetting are you guys running? Interested in both pilot and main.
