thaks for the tip anyone else know anything else that i should change when i put the pipe on

132 or 120 main - people's opinons will differ.
45 pilot
stock needle on the 4th clip down.
fuel screw 1.5-2 turns OUT from fully in.

and take the snorkel out, and now uve just re-jetted and netted more power in the process and are no longer in danger of running lean.

Nobody does that, most use the Honda PowerUp kit jets or something similar to heybuddy1901's set-up.
BBR does that for political correctness, plus assuming you're leaving the airbox stock-a mistake.
A 14-15 tooth countershaft sprocket makes a huge difference, BBR will recommend that to you and you oughta do it. Doug
