with that large of a carb you dont have a strong enough "signal' to properly atomize the fuel at lower rpms.I suggest that you try a smaller pilot jet (prolly a 32 or 35).your mix screw should be set at around 2-2.5 turns.
Crazy jetting problem!!!
This is driving me crazy!!!!!!!!!!!!!
As some of you know, I installed a 30mm Kehin PD Carb on my CRF230 replacing the stock 26mm PD
It has a 40 pilot, 1.75 turns out on the fuel screw, 37D slide, 85A needle, and a 158 main.
Engine has a 11:1 piston, BBR Cam, BBR Pipe and some mild head porting.
When running the bike at WOT, and then rolling off the throttle (not chopping the throttle) the engine momentarily cuts out, and then recovers.
Not a huge issue when in the dirt, but when mid corner racing SM, it could really ruin my day....can you say highside!!!!!!!!!!!!!!!!
