Greetings all from Sunny San Diego!

Introduced myself in the Newbies section of the Board and as recommended Im starting a thread on my CB750K6!

This will be my first foray into the world of motorcycles and I hope to retain all my fingers and whats left of my sanity (not putting any money on that though).

Thought I'd post a few pics and let you know where Im at with my build, as you can see the Cam and cam holder are shot (why i got such a deal on the bike, only $900 bucks in California) and the heads and cylinders are at the machine shop for a valve job and what ever else the Machinist recommends.

Also, can anyone back me up on the Vin number and make sure its a 76 before I start ordering parts?

Im also open to any and all recommendations and advise for a first time build.  Parts, Supplies, Shops in San Diego, and Doctors and Psychiatrists.

-Tim

Welcome to the board Tim.

You do indeed have a 76 cb750K, based on your frame #

That tank however is from a 75 cb750K. That colour is flake apricot red...only offered in 75. It's a rare colour.

Contact Bill Benton for parts. I think you might have to get your post count up in order to send private messages.

Check out Lossa Engineering in SoCal...Jay and his crew have built some amazing 750s.

Thanks for the Reply's guys, I know there are a lot of other people doing similar rebuilds so its encouraging to get feedback.

Love the color of my tank too, haven't decided on paint yet thats wayyy down the road. Ill have to hit up Bill Benton when i get my post counts up, maybe he can help track down some oil jets for me.  From the research i've done so far its my suspicion that those oil jets became blocked and thats what caused the camshaft to loose oil and fail. 

Good news is that the machinist said the cylinders looked good and only one piston had some rusted oil rings, between that and 4 new exhaust valve guides and I should be good to go on the heads. (Not sure what else I really need to replace on those guys)

In the mean time I removed the oil pump and discovered another surprise (see pics), not sure what it is or if anyone can help identify the culprit, but to me it looks like the shavings from the cam chain tensioner. Or possibly gasket material? (see posted pics)

As far as ordering parts, what are your guys favorite places to get parts online (or in the So Cal area).
