I must say.. other than the frame rails preventing topend removal.. the CB 750 is one of the easiest engines to work on..
I have mentioned to many folks over the tears, that if they cant pull thier motor down to the main bearings without special tools, then theirs is more complicated than a Honda 4. You do need a tool to remove clutch... can be done without, but will ruin the nut after a while..
very userfriendly motor...
