1971 CB750
« on: September 07, 2008, 09:00:58 PM »
Got this from my step dad, it has been sitting in the garage since 1982, started working on it last August.  Just one of many 750 projects I have...sigh.  Someday i'll stop playing around and get me a sandcast(pipe dream) but most likely diecast 750.

G`day mate
You started out with a couple of freaky pics, but the following images are a big improvement and looks like your doing one hell of a job on the old girl.
Looking forward to seeing more pics of your work

When I had the engine out, I completely degreased the engine than used wax to polish it.  That is the original finish on the cases believe it or not.

Subscribing to this thread because I'm also returning a 70's chopper to stock (well, maybe some Kerker pipes).
My bike was originally flake sunrise orange, going back with that color. Can't understand why one of the previous owners decided flat black was more attractive than the metallic orange.

Nice work, keep it up.
More pics.

Now your being part of the community.

 The orginal state of that bike is amazing. One day I will find something like that, get it running and ride it in its "moded' state.

Did you use the wax polish on the valve cover too?  Did you have to remove the clear coat?

A sandblaster and a Bench buffer are your friends in dealing with the aluminum parts.  It's alot easier to blast the aluminum parts before buffing them than it is to just straight buff them until it burns through the clear coat.

It's not actually being returned all the way back to stock beauty, I do want to capture the stock lines but with some subtle changes(note the finned engine covers), stock is boring thats why these bikes were so heavily modified in the 70's!  There really wasn't much salvagable from when I got it so it would cost way to much to be truely stock.

WOW. I found a 71 750 with the same chopper look and I am just about done turning it into a cafe! It's hard for me to believe that someone did that to CB on porpoise!

I love that original chopper look, reminds me of that movie "Every which way but loose", ha ha!

As much as I like "showroom original" bikes, I was there "back in the day" (I bought my first CB750 new in 1978) and they didn't stay "original" too long, there are probably more "showroom original" CB750's on the road now, than there were then.

Keep up the good work mate, and send me all the old chopper parts, I want to preserve them for posterity, ha ha! Cheers, Terry. ;D

I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Some updates:  Had my hubs mated to some new shouldered excel rims and installed some funky rearsets.

Hey nice wheels mate, they look like period "Borrani's". Not too keen on your rearsets though, definitely "period" again, but they look a tad "agricultural". Just my opinion though, no offence intended, keep up the good work. Cheers, Terry. ;D

A question I have always had but was afraid to ask...  what is the big deal about sandcast?  Why do you want a sandcast?  I wouldn't know a sandcast if it rolled over my foot.  For me, if it looks good and runs good, I don't care if it was "turd-cast".  Now, please all jump in and brutally educate me on my ignorance of such matters.  ;)

Ok, I have a Dilema.  I have a NOS K1 Tach and two NOS K2 Speedos.  Im thinking of using the K1 Tach and K2 Speedo together.  For those that don't now the K1 gauges had the "dummy" lights built in the gauges, the K2 and on used the handlebar clamp thingy.  The Tach has the Neutral and Oil Dummy lights, quite honestly the only two warning lights I care about so it might work.  Ill mount them up later and take a pic to see what it will look like.
