Valve timing and sequencing on a four-stroke being what it is, I can't see how you could make one run backwards. Or how you could 'mistakenly' reverse the input from crankshaft to tranny. It would take a ton of dedication and work to achieve that. I think someone is messing around here....

Tell me... if you went to pick up your bike and in the course of trailering it you realized it ran backwards... would you leave your bike there for them to work on again? :laughing:

why not let them fix it for free. then pay someone else to do a retunine check for 1/4 of the price, instead why take it to someone else and pay the same ammount to fix it nearly twice?

Actually, the explanation is rather simple and has nothing to do with the engine. The hamfisted mechanic failed to mount the chain on the drive sprocket but instead got it wedged between the sprocket and the swingarm pivot. So instead of the sprocket rotating the chain counterclockwise, a couple of teeth engage the chain, pushing it up and clockwise against the swingarm. End result is the drive wheel goes backwards!

Moral: always check over any work done, no matter how much you trust your mechanic (or yourself :)
