[avagabundo]

"in mexico, do not have yamaha mechanic for usa models.

runs fine until about 2/3 throttle then starts cutting out and goes back to about 1/2 throttle, and eventualy back to 2/3."

"Jim,

Probably some debris in the carb, but before you take it apart make sure the throttle linkage is moving freely and that the timer base if free also.
