iT DIED ALL AT ONCE . like no spark, battery had full charge , I turned it over every 1/2 hour to see if it would start while I was waiting for the tow truck, next day I put the new REG., on and it started up and runs perfect,. running back and forth to Orleans about 15 miles, got it up to 106 Kmph, felt like it could go faster , but I was at my turn off,. I think 90 kliks is fast enough for that small scooter,. RPM gets to high,. wont fool with the variator until I get a flat belt sander again,
