[5valve]

Engine was apart already 2 times, unrelated issue, main bearing failure.
Worked flawlessly for 30 hrs since.

Alu impeler is not damaged and cant enter gear/clutch.
Gearbox didnt get stuck, it seems like some foreign piece on the clutch side temporarily jammed under outer shift fork, freed instantly, and got ground all over the place.

No magnetic debris whatsovever.

I've inspected everything on the right side, and there is absolutely no damage or broken off parts from case, clutch basket etc. Checked clutch plate by plate..nothing unusual. @95 hrs like new.
Also, by my knowledge, the is no aluminum engine parts in the gearbox, except cases, so nothing should come loose, even alu washers are not present.

Flushed with gasoline today, will do some more, guessing 90% clean.

Might forgot sth in there that lasted 3 service intervals, time will tell.
