GnarlyCharlie4u's 1977 CB750K - Getting Very $erious.
« on: October 15, 2010, 11:37:34 pm »
Check my blog for progress.

^^please feel free to comment, it's nice to know that you're not just talking to a brick wall.

Well what can I say...

I wasn't exactly ready to start a project thread yet. I just finished getting her running in good shape and I've only ridden her a few times.
Then she decides to #$%* the bed, and throw a tappet adjuster screw @ 8,000 RPM.

The screw is toast, the nut is lost somewhere under the valve cover and there's metal shrapnel in the valve train. Although I managed to get most of it out by using a magnet and screwdriver, the nut is still M.I.A.

haha thanks man. at the moment I hopefully only need a tappet adjuster screw and possibly nut.

It figures that this happens not 4 hours after I decide NOT to buy that complete top end on Ebay for like $20.  :-\

that reminds me... I have an assortment of horns for you to choose from. I'll come see you Wednesday.

Yes. Thank God for gravity. I first laid it over on 2 tires but that put the motor at an angle instead of flat on the ground. than made things a lot more difficult than it needed to be. That is how it got scratched.

did that oil pan show up yet??

Not yet, maybe today? I am an idiot though... I can't seem to find the oil pan bolts. I think they may have gotten thrown out with the pan :(

seriously right after you said shipped I thought to myself... "oh wait... bolts? uh oh."
No worries though I'm sure I'll figure it out. I'm getting a dresser bolt set so I may just go with hex allen heads.

Don't forget about my for sale thread, I have lots of stock parts for sale! 

please link your shameless plug here.

Thank you I really appreciate that. Incidentally if anyone has requests for specific pics of anything before (or while) it gets totally torn apart please let me know.


My camera, click for information/review from Ken Rockwell

pretty sure all those were taken with my 50mm f/1.8 lens
I'd have to check the exif data to confirm.

Dood, is that in your house?
I don't have a motorcycle, sold it ('85 Yamaha Venture Royale).  Haven't had a CB750 for over 40 years.

Garage, yes.
And yes I did carpet the garage :smug:

I have white carpet for when the red totally craps out on me. But I'm afraid that will get too messy too fast.

alright you know it's bad when you forget that you have a build thread.
sorry for the lack of updates.

Right now I'm about to go pick my cylinder head, jugs, and cam up from manassas honda. I dropped them off to be checked and the diagnosis is not good.

There's water damage to the cylinders so they'll have to be bored.
I goofed up taking off the gasket material and the head is out by .003" in a spot so that'll have to be leveled.
Surprisingly the cam is still in good shape though.
