any ideas on jetting
DG only #250 main.
32:1 + 1 size main..... 25:1 + one more.
Airbox lid off + 1 or 2 on the main.
Needle on middle clip, plug chop to confirm jetting.
I keep from shuddering that you are running a DG header and seem to want performance.
A DG will give you that little more, but with your home port job a FMF Fatty or a DMC Alien will Ghast your Flabber and give you so much more.
3 to 5 heat cycles, 2 tanks of gas at no more than 3/4 throttle then grip and rip.
