CB750 / Re: Primary chain k2
« Last post by Martin6 on May 30, 2024, 11:49:30 PM »Yes, 70mm for the CB750K. I left mine alone at 68.2mm until I next take the engine out, as I had no other reason to go into the engine case. Maybe should have done it, if I had the opportunity again, I would, but I didn't know the top end would go back together so easily at the time and didn't want to get in above my head.
I have 40,000 miles on mine, so 1.3mm wear or 'stretch' per 10k, if it's linear!
