Just a bump on this. Been a couple months now and, although the cops have busted some car theft and bicycle rings lately, they tell me there are no CB750s stripped of vins and plates sitting in a lot anywhere they know of.
Been keeping a close watch on CL and eBay for the only identifiable bits on the bike since it was mostly stock. More eyes are better of course so maybe, in your travels on the internet, if you see these, let me know.
Mirrored dual disks with a swept pattern
Debadged header wrapped Kerker with a worn spot on the 3 pipe where I didn't zip the speedo cable back out of the way and a scrape on the can.
The only other identifiable bits I can think of are:
The tank has a dent in the left hand side where the bars slammed into it when it got knocked over by a crap motorist. Also it's been Kreemed.
The carbs still had permanent marker on the bodies - 1,2,3,4 - airbox side - and the number 3 carb has a JBWeld repair where the PO punched a hole in it with a screw driver or something. Some gouges to boot.
I know it's a complete and utter hail mary at this point but weirder things have happened. Thanks for looking.
