Rich jetting, worn out piston/rings, ignition issues, worn reed valves, and many other things. Dive in and fix it.

will a larger main and pilot do the trick or will you need to adjust the clip position? becuase i hate moving that damn clip

@Relinquish8t

The video is about the pilot circuit, nothing else.

The added compression may make it leaner.

[slaverace1]

Both.

Watch the video again.

I'd rather bang my head against a brick wall than jet a 4 stroke or make a 4T video.

@4NICKW high rev can also be caused by the carburetor. A faulty throttle cable for example. If it is binding up inside the plastic tubing, it could prevent the throttle from returning to idle position. Also, the return spring could be bad. On my 1995 ktm 250 exc, I had a similar issue. I had to popstart the bike (long story). one time when I started it, it took off, high rpm. i pulled the clutch in and it continued to scream. after inspection, return spring was the issue.

I havd a 1999 ktm mxc200. its hard to start. (takes about 15-20 kicks). and once it starts it starts revving really high. I Just replaced the rings to help with compression. Should that totally fix my starting problems? and is the high revving just from me flooding it? or is the carb needing to be adjusted?
