My son bought a CB350f for $700.00 that ran but obviously had been abused cosmetically and mechanically (list too long to go though here). He's not mechanical at all and he didn't consult me about it prior to purchasing. I agreed to help him work on it. My problem is I'm a bit of a perfectionist and it's his money (or lack of) were using to do this project with. So after tearing down the engine because it was severely weeping oil and I noted it had more than a one loose and or stripped out bolt in cam cover, head and case, I'm seeing that the cam and journals are in pretty bad shape and the valves have major carbon build up. The pistons and rings were replaced recently and it looks like the cylinder walls have been cross hatched. I haven't taken any cylinder measurements yet but the cam journals and lobes are in tolerance, albeit with a some deep scratches. The rockers look horrible.
So with very little budget to work with at least right now (he's still in college) and assuming the cylinders and pistons are OK (big assumption)
Where would you spend his limited funds, or maybe I should just put it back together as is, re-gasket, fix the stripped out bolts and let him ride it until it needs attention. I'll probably end up throwing some of my money at it too cuz I'm enjoying the project and this bike was basically my first bike (CB400f) while in High School.
