Question about Honda XR 200 Motorcycles
Hi, I have a 1994 XR200, I got the bike from my older brother (hadn't been run in a few years), after changing fluids cleaning the carb the bike ran terrible. So I worked on the carb, the idle is now great the mid range is great but in high speed or high RPM the bike revs up and down. I took the carb apart cleaned it and made sure I did not miss anything. I took it for a test run but bike is still revving up and down at high end. I have been cleaning everything and working on the bike for about a month. The only thing I cannot fix is the Revving up and down at the high end. What could it be?
You are on the right track with the fuel system. Maybe the fuel filter, There is one in the tank also, I think. Try running on reserve if you have it.

Sounds like a fuel problem, possible stuck needle valve. Did you check for vacuum leaks? How about the fuel itself, did you treat it before storage to prevent gelling and varnish ? If not your entire fuel system may be restricted. Purchase a can of Seafoam...pour in 1/2 of it to a tank of gas, use the other 1/2 on the next tank. Change fuel filter afterwards because any foreign materials will be in the filter from the cleaning process. Third tank normal fill.
Good luck...i hope this helps.

did u install new gaskets, the engine might be sucking air from outside the carbs. u can use a propane torch (not light) spray a little around outside of the carbs, see if engine sounds different, if it does... leaky gasket.. u might check there is no unplugged vaccum hose.
