Hi everyone,

Looking for some guidance- I’m Running stock motor Vforce reeds stock exhaust etc. and started running T2 (works better than AVGAS in warmer temps) and was wondering if you anyone has any jetting recommendations. Sea level, about 80-90 degrees this time of year in mid-Atlantic. Any insight would be great!

How is the bike running with your current jetting?

Stock pipe and stock motor on my 05 with C12 and stock jetting runs pretty damn good.

I had to add 3% to my jetting (470 to a 490 MJ and 32 to 37.5 on the PJ) since its hotter now I had to back the PJ down to a 35 with the temps 90+. That was switching from C12 to u4.4 or T2. I have T2 in the tank now.
