2001 Road King, 98 big bore kit, 10:1 compression, Andrews 37G cams, CV carb, RB Racing LSR 2:1 exhaust. Stock heads, springs.

Just trying to get some opinions for a starting point.

Thanks for your input!

 

Just for S&G, I went with a #50 slow jet and a #200 main; it ran much better. Got a little bit of a backfire, when I decel from high rpm, could be too lean still?

Previously, I had #48 and #195.

 

Backfire when cold= lean
Backfire when hot= rich
Raise your needle?
Might even have to go "richer" to offset the ethanol in your fuel.
How many "turns out" are you?
