I was riding on our test track a long time ago. I just about stalled it, I grabbed the clutch real quick to catch it from stalling. When I let the clutch out (I was still rolling forward) The bike acted like I was applying the brakes. When I came to a stop I let the clutch out and it started going backwards.
Of course I was riding alone and no one saw it.....
Pretty weird I thought.

Thats the only thing I can figure too. Maybe the flywheel key sheered?
The timing is off. It's not that big of a deal.

Maybe the flywheel key sheered?
I wouldn't think so, mine never missed a beat afterwards......

On my '83 Husky 500xc I had that happen in the middle of a stream crossing! (Good laugh for my ridding buddies) I glanced off a submerged rock throwing me off balance and chopped the throttle and pulled in the clutch, turned the bars hard to regain balance while letting the clutch and tweaking the throttle all at the same time. Almost went over the bars and fell in to drown the bike and myself. x2
Had it kickstart backwards a couple times too. You have no clue until you let the clutch out.
Just the other day I read that 2-strokes by design, can run in either direction.

You notice that it's big bores chiming in on this subject. I personally feel that it's not a timing issue, (at least in my case) but the inertia of the engine. IE, major crank weight spinning and you almost stall. The stall point happens to be at the precise firing point of the engine BTDC...hence making it fire and propell the piston backwards reversing the rotation.
Let me rephrase: timing is an issue with bikes that are timed very close to TDC. That coupled with the fact that there was this considerable mass rotating in my 500, was the reason for my backwards motion. I didn't change anything because everything was spot on and the bike hauled azz.

Considering the source (Yamahahaha owner), I don't think anybody took offense.
Ifin ya wants to get down and dirty, it's actually 'Yamamaha'.
