I installed this on my bike and am having troubles getting it running properly, it’s running super rich and 4 strokes a lot when I accelerate and fouls plugs very quick, I have the needle clip set to the leanest position and I tried all the pilot jet sizes that came with it, 0.41 0.39 and 0.38 it ran like crap with all those so I got more jets and went all the way down to 0.32 the smallest I got and it still doesn’t run good and fouls plugs. As you can see in my photos I also have a expansion chamber pipe and a high compression cylinder head and am running a windowed piston as well. I haven’t tried changing the main jet cause if I’m not mistaken the main jet is just for 3/4 - full throttle and I’m trying to get the low end dialed in before I bother with the main jet and the motor still needs to be broken in anyways. Cylinder is tourqed to 140 in/lbs and I’ve tried ngk br5hs br6hs and br7hs plugs and all the same results. I’ve tried adjusting the air/fuel screw to all different settings with all the jets I mentioned but it still wouldn’t run right. Any advice would be appreciated. Do I need to keep going down in jet size?

Do you have a 'window' piston & 3rd port in the engine?

Yes I have a window piston it came with the dio reed valve and cylinder. What do you mean by 3rd port?

Wondering if the carb isn’t level enough and you are just flooding it with fuel.
