Hello guys again.
I am newbie ,that started my first resto on my CB 750 1972.I'll post some pictures when I;m allowed.
But after took apart hole bike ,started working on engine.Before that red lots of this forum to see am able to do it.Have a faith that  you guys going to help me with this .Engine was seized wasn't any chance that it could move it.Try everything !
After I took of camshaft and camshaft holder sow that one of the bearing surfaces on camshaft and camshaft holder is badly weared .That is first one after sprocket
I'll post a picture later .
So I am wondering can I used one from same bike year 1975 to replace it and camshaft and holder ?I bought  another motor CB 750 1975
Thanks guys
