Of course what works for someone might not work for you but here is mine

HMF, GYT-R filter with outerwears and no lid.

Your stock jets are 22.5 pilot, 142.5 main.

Mine.
Pilot jet 25.0
Main 155.0
needle clip in middle (same as stock)
air screw approx 3 turns out.

Start rich on the main jet so that it stumbles at wide open throttle and then go smaller till the stumble disappears.

No. I did not mess with that white washer. When I first got my HMF pipe I did not have the GYT-R intake for about 2 weeks because of a mail fubar. So I did not mess with the jets and just dropped the clip to the bottom per HMF specs. After I installed the intake and removed the lid I jetted the carb and put the needle back in the stock position.
