Yes I know I shoulda been carefull, I actually know all to well, as this is the second time I've done it, and was going REALLY slow and just getting em up to torque and it had the feeling that I stripped the bolt, you know that feeling when your going real slow and you know something isnt' right!! so I backed it all off and sure enough there's a crack! so what did I do?? of course I broke off the piece with my hands to see how cracked it really was!!
So, if anyone has a basket case engine, for a CB750, mines a 74, but I believe this part is universal. I'm sorta desperate!
