Your bike breaks in February, you drop the motor and rebuild the rear cylinder, drill out the exhaust studs and retap the head, get all new gaskets, throw it all back together within 4 months. Ride it around the block 3 times and you get a heavy knock?
I just pulled the motor out again last night to assess the damage/noise.
Issue found: work rocker arm on the intake valve and a rounded valve stem.
Looks like the intake pushod went up, pushed the valve mostly down (seeing as it still ran) then slips and runs down the springs.
By the time I'm through with this bike I'll have had it completely apart 3 times now.
If I didn't have bad luck, I wouldn't have any at all.
