My son ran his '02 XR200R out of oil last summer and did quite the number to it... Now it has been redone from the crank up. .006" over, new con rod, piston, rings and pin. New timing chain, guids and sprokets. Rebuilt head, new cam and valves. The compression and leak down test were perfect. The carb has been taken off and cleaned 3 or 4 times now... checked and rechecked the float level. We even tried a brand new carb and still always the same??? Even warmed up it needs half-choke to start. It'll usualy fire up on the first kick, it won't stay running unless you feather the throttle. No throttle, it dies, to much too quick, it boggs and dies. When you just feather the trottle a bit and work the RPM's up the tone changes... like the engine just comes alive and then it'll runn like hell all day long, but it has to stay at a high idle at the very least or it will bog down and die. Somebody told me it could be a bad stator... can it be??? Something about a high side and a low side, and the low side is bad? Thanks for any imput, this one has me stumped. Steph.
