I found one place online but will see what my next main jet change tells me.

Lean spot AFR 14.8 to 15.5 is at just cracked throttle and clears at 1/8+ but is worsening as the main size drops, rich on the main now 170 with AFR at 11.4 +- WOT.

Thanks for the feedback on the mirrors going with the Ken Sean.



I got the Adj air screw 2 weeks ago from Power Barn. $12.95 shipped.
