no it ran smooth since day one, this engine has roughly 150 miles on it, this is my "around the neighborhood" bike. about 2 miles into the ride today, i heard the grinding for the 1st time and quickly turned the engine off. inspected what i could without any tools then tried starting it up again with no luck, it just didnnt engage. i ive never taken the clutch or the crankcase apart so im assuming the woodruff key didnt have a chance at coming out. looks like all i need is this: http://www.bikeberry.com/engine-kit-...vel-wheel.html
to make it run again.
