too much fuel in the mix?
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!!!!!!!!!!!!!!!!

it got me thinking about your exhaust as well.... there might not be enough flow through to suck out the exhaust gasses, which might stay in the cylinder for a little bit longer, especially when you've been throttle happy and then you chop it
