posable disaster with my 650

(1/7) > >>

RickyC83:
he guys so updates on my build been a busy weekend.
got the loom patched up and working after a bit of tinkering got the starter motor turning and sparks. didn't get the bike to fire but oil was reaching the cam and sparks was strong, so figured some work on the carbs and we may be in business!

but then the starter stopped turning, turned out the engine seems to have locked up, in top gear i can turn the wheel a few degrees theirs a bit of a click and it stops, turn back the other way same thing,

any hints where to start would be appreciated

when i bought the engine i was told it had been rebuilt then stood. so basically know nothing about it (1980 cb650z)

If there is very little momement in either direction I would suspect that the cam chain has dropped and is jammed in the casings. A strip and rebuild required.

RickyC83:
That's what I'm thinking. Thanks.

fisjon:
Just to be sure, remove the starter, get it into neutral and try turning the engine by using a socket on the left side of the engine (generator side)
Don't force too much just in case, if the cam chain is still ok the engine should turn and the fault could be with the starter mech.

RickyC83:
Starters out and still the same
