bougth bike with 11k rode to 18 k over two years. head plug always leaked but became a problem when some head cap bolts broke. dropped engine took off head cap. drilled bolts. this seemed like a good time to put on cam adjuster extension. popped clutch cover, looked, wiggled clutch pack, think pushed it out of tdc. stupid pin dropped out. cant imagine that it fell out of the rabbit holes but nowhere else it could have come from. its not oil pump drive gear pin or the pin behind the circle clipunder and right of clutch pack
