Honda cb750a opinions
« on: November 04, 2020, 03:43:08 pm »
Hoping for some expert analysis of a machine I picked up.  Was on Craigslist and I grabbed for 350 with title as I have a normal 1974 cb750.   Thought it would work for parts but looks like most are different.  It has 16000 some miles and unless he finds it is missing the exhaust or half of it and the cover for the tranny.   It is stuck from sitting I am told.   Don’t know much about the hondamatic and was hoping you guys could say part it as it is missing ? or it is worth squirreling away and keeping an eye out for parts.   Tank is fairly clean.

  I'm at the finish line of restoring my 76 750A. The missing converter cover should be easy to find on Ebay.  The exhaust is harder to sort out as aftermarket exhausts for regular 750s mostly won't work. There are some threads on here about it. I wanted to keep mine as original as possible (4 into 1), so I ended up getting the rusty pipes blasted and silver ceramic coated. I wasn't spending $2,200 for the one NOS exhaust on Ebay, but you can see what it should look like https://www.ebay.com/itm/Honda-NOS-OEM-Exhaust-Muffler-Set-1976-CB750A-Genuine-Honda-Pipes-18200-393-000/323460896862?hash=item4b4fc5985e:g:NvoAAOSwe-FU5371 . The other two year models were 4 into 2. Of the three production years for the 750A, the 1976 is unique in several ways from the following two years. The exhaust, seat, wheels, gauges, I think the carbs, and one or two other things are one year only for 76, but pretty much everything interchanges from the other years.

Ok.  Good info.  I will have him keep looking for the muffler.   Pipes are ok.  Just missing the muffler. 

I have been reading up on them.  Pretty neat bikes and as I have the title I will keep it together.   I don’t have time right now but will oil it up before storage. 

Thanks

 I drug one out of a fence row last year just to get the wire spoke aluminum rims for a performance bike I was planning.

No matter how many times you paint over a shadow, it's still there.
If you love it, set it free, if it stays it's probably one of my 750's.

Half-track, you may have already done this maybe not.
Pull the spark plugs and put a little anti-seize on them
if you are going to store it.

I bought mine a few months ago after being out in the weather
a few years partially covered and I'm battling broken plug threads now.

Looks like yours is in pretty nice shape

Aluminium paste is perfect for plug threads. Plugs will go in and out by ease.
