Lifan 200cc in XR200 frame, having carb setting problems
So I put the lifan 200cc engine in my xr200 frame, but in order to mount the battery I had to put it in the air box. That leaves me with using a pod air filter on the stock xr200 carb and I can not figure out the right jet and or needle setting, nothing seems to work. Has anyone done this and have an idea of at least where to start? The best I could get it running was with the needle on the middle setting, fuel screw 1.5 turns, #40 pilot jet and 110 main with the pod air filter covered about 3/4 of the way. But this only works untill it gets warm then just dies when I take the choke off. I got the engine brand new so i assumed i didnt need to verify the timing and valve clearances, was that my first mistake? Any help appreciated
