im a little bewildered, i wanna use my bike for transportation to work.
im having issues with what seems to be 4 stroking, ive messed with all of the settings of the needle. i dont know for sure what motor it is, it looks like a jet silver. little head nuts, shorter fins on the side of the head rounded edges on the cylinder compaired to most chinese engines. it has the square gromet for the magneto wires, and came stock with cast intake not the steel welded one. the only one i have seen that looks like it is the jet brand engine. i also dont know what CC it is, the guy who use to own a MB shop that sold these kits told me when i bought it from was a 66/80cc, but when i compaired the dia of the piston to what im sure is a 49/50 cc engine it looks the same and other than a much more stout build as it looks to me looks like a 49 not a 66. so how do you tell the difference between the two?
as for my problems i have what seems to be the 4 stroking issue as i said above and im not sure what to do, no matter the needle setting i cant get it to run right, either no power or 4 stroking, cant find a medium.
just playing around with it, i was able to get it to run right with a load on the engine using the back brakes(not always the smartest thing im guessing) but it started smoothing out but soon as i let off the brakes it accelerates then once it gets up about to 75-100 it does the 4 stroking, but at that point i can only do about 20mph.
when i start from a stop it 4 strokes a little under half all the way up to full throttle.
im sorry if i may sound a bit short and blunt in past posts im not trying to sound that way at all just busy all the time and dont have the time to make a detailed post like this.:helmet:
