Need some advice from the knowledgeable TROOPERS. Riding home the other night, I shifted into 4th, when my RPM's started fluctuating. I was able to accelerate, but it struggled. I pulled in the clutch and bike stalled. Bike has not started since. Checked valve clearance and cam chain, no problems. When you activate starter, you hear something in left side case, like a chain is broken. Does anybody have any idea? I had the recall done.
