CB750 Super Sport. This ain't right.

archmill:
Have now stripped the engine completely. It's been rebuilt in its short life (16000 miles on the clock), registered in Sept. 1979 and the last tax disc July 1981. The LH cam carrier has bronze bushes fitted which I have been told was never a factory fit, four of the rockers have been dressed with a stone and there's no chrome on them. There's a chip in one of the barrels, a lovely half moon impression on the top of one of the pistons (guess it was a valve head) and the cranks on its last legs. Here's a photo of the oil pump filtre.
That ain't right, is it? LOL.
Anyway, I am looking for a crank or is there some way to reclaim the original?

LesterPiglet:
OMG! Slight bit of damage then. Sorry I can't help you.

Bryanj:
There are no undersize crank shells available but i believe SEP in kegworth will do it if its at all possible, otherwise i think all the 750 cranks are the same and wear is not  a common fault

Spitfire:
That oil pump filter looks nasty.

Cheers

UK Pete:
WOW with all those bits on the pump  i imagine it has been treated quite bad and had an amature doing the previous build
