cb750 cam timing

(1/2) > >>

750rideruk:
On rebuilding my cb750 K1 I find that on lining the T mark 1-4 up the cam line is slightly out of level but not as much as one tooth on the camsprocket. I have fitted a new cam chain. Anyone with any ideas or is it OK to continue?

Bitsa (Ralph Wright - RIP):
Is this with the tensioner fitted?Photos of the T mark and the cam would help.If you have not got the tensioner on with the difference you describe could be it.
Cheers
Bitsa

750rideruk:
Only very slightly out of line. is this OK

tom400f:
Bitsa is suggesting that backlash in the chain, if it is not tensioned, might account for the discrepancy. Perhaps wind the engine backwards some way then approach the timing marks in the correct direction of rotation only. Do they line up then?

750rideruk:
I have tried that to no avail. Atiming disc show about 15 degrees out but not as much as one tooth on the camsprocket. Starting to think its a faulty chain but seems a bit far fetched
