What year motor is this thing? If it's still got switch boxes, and a stator, I'd start there. Might have a high speed stator coming and going.

THIS THANG IS BETTER THAN THE NAMES I'VE COME UP WITH,IS A 1989.I HAVE LOOKED FOR ELEC. SHORT,ALMOST ACTS LIKE ONE.YOU CAN BE CRUISING AT HIGH END OF IT'S LIMITED RPM RANGE AND YOU CAN TELL WHEN IT WANTS TO RUN,THE RPM'S WIL CLIMB WITHOUT MOVING THROTTLE.YOU THEN GIVE HER THE GAS,AND AWAY YOU GO!<br />THIS THING HAS JUST ABOUT PUSHED ME OVER THE EDGE,ALTHOUGH IT HAS NEVER LEFT ME STRANDED.<br />THANKS FOR REPLY.
