cb750stu:
Hi folks I've got a couple of questions about cam chain adjustment ??

Does anyone have a idiots guide to doing it please ??
Is it best adjusted when the motors running ??
Does anyone have a spare adjuster lock bolt for sale my one doesnt look right !!!

Cheers Stu

Bryanj:
NEVER with the engine running on a 750, the lockbolt is a standard 6mm threaded bolt and nut, I have repeatedly posted a method for tensioning please try the search function

Hi Stu, the camchain adjuster bolt and nu are just standard M6 items, I replaced mine with stainless steel items many years ago, and no problems ;D As regards chain adjustment, I certainly WOULD NOT try doing it on a running engine :o I seem to remember that you wind the engine over with a spanner on the crank in the points cover to just past the "T" mark,so that the spring peg of the advance unit is lined up with the timing mark on the crankcase, that way all the slack in the chain is at the rear, where the adjuster can take it up, whatever you do, if you go past the mark, continue around again until it's lined up, as trying to wind it back even a fraction will result in the slack being at the front of the engine, which is no use at all! :(

Cheers Guys i took of my tappet covers on cylinder 1 (left hand side of bike) then cranked the engine over til the T mark was lined up with the mark then turned it till the spring peg was lined up with the same mark ??

At this point should the valve adjusters be loose ?? I cant move mine they seem solid ?? Do the valves need adjusted ??

Cheers Stuart
