OK, I just finished rebuilding my top end and it runs great. However, I am running an FMF Fatty pipe w/Boyseen reeds and I am not sure what main jet to run. I understand that tweaking this to perfection takes testing, but is there a figure to start with, so I can buy 4 jets or so... I ride a YZ125J1 in the MD/DC/VA area (sea level) with temps right now hitting 70s, soon to be higher. Considering I am running a high performance pipe and reeds, how should I adjust my jetting so that my bike rubds safely, without overheating? Is there a rule of thumb to follow here? Thanks in advance for all of your help with this. This is the ONE area of MX knowledge (OK, OK BESIDES changing fork seals) that continues to elude me!
