So my bike is about halfway through break in, and it is 4 stroking a lot. It has a little band at about 1/4 throttle where it runs properly, but the rest of the time it 4 strokes. My question is are there any serious problems which arise from 4 stroking, and should i wait until the end of the break in period to tune the carb? Also i am using up the last bit of my 16:1 gas mix, i am switching to 24:1, will that help? Thanks!
