Building a NEW CB750, is it possible?
« on: July 13, 2007, 05:26:33 PM »
Just read an article in Cycle World about a club selling kits to build your own new Vincent.

There are lots of parts still available from Honda for the CB750.
There are several companies selling reproductions of most other components.

So I wonder: Is it possible to build a CB750 using all new parts?

A few years ago, one of the cycle rags did an article about building a complete CB750 from NOS parts.  I can't remember which magazine did it, but it was done by this guy:

Been there, done that.
When it was done, it was so new that starting it felt like it was going to ruin it. I mean, it had no used parts on it and was completely virgin. No carbon in pipes, no gasoline ever in tank, seat never sat on, etc. Stopped counting what it cost. Sure looked nice, absolutely sparkled. It was more like artwork than a motorcycle.
Now I prefer to restore CB750's so they look unrestored and ride 'em.

I am so completely jealous of that candy-blue K0!   :P

736: are you sure you don't want a blue-cased ignition box on that one?

You can see them here: http://www.alliedelec.com/catalog/pf.asp?FN=593.pdf

This is what I built for Magpie and am building right now for Steveko. Mag's was red, Steve's (and Terry's) gold. Mine is blue, in the hopes that the bike will match after this winter.

I ended-up trading it for 2 unrestored original paint sandcasts and a van full of parts.  Talk about instant gratification; it was a perfect deal. The other party wanted a finished sandcast and I wanted to tear-into bikes that hadn't been touched.

Is that blue in these pix the color Honda now calls "blue-green"? I saw this place where someone is selling "original color" Honda resto paint kits, and they list blue-green as the only blue. Yours is the color I want to paint mine: I thought they called it "sapphire blue" back then.

That should be Candy Blue Green. I think.

That sure is one fine looking bike 736. I started wondering about this after feeling drained about having to repair, rebuild, replace, etc. almost every part of my project bike. But after looking at your creation I realize it would be a gigantic task to research and source the complete bike.

How long it took you  (I won't ask how much)?

Then this morning I read the thread from Phaedrus that Honda is making it's new replica and all of my efforts now seem pointless.

The sapphire blue was used on the 550F.

  Took about 3 years. It started with a totally bare-bones bare early sandcast frame found in a Pennsylvania junkyard. There wasn't 1 part on it, not even a single #8 bolt. This was around the time I was beginning to restore 2 other sandcasts, so now I had 3 to play with, and envisioned how neat it would be to line-up 1 of each color. I was definately on a mission: a NEW CB750 candy blue-green sandcast, a 100% correct original candy ruby red sandcast, and a 1-of-a-kind candy gold sandcast (just like the pre-production CB750). Each would be correct AND factory Honda original paint.
   I asked around looking for a matching # sandcast motor for the bare frame and luckily sourced a bare set of cases in Minnesota at M3 Racing. Incredibly, the #'s were within 100!. I commissioned Mark McGrew to build an entire correct motor and met him a year later at Mid-Ohio VMD where I picked-up the completed motor. All this time, I was gathering parts from all over the world; a nos 8 piece set of bodywork from Canada, a super-rare nos ducktail seat from Florida, HM300's from CMS Netherlands, gauges from Japan, and most of the rest on ebay and, of course, from Honda. There was much chrome and zinc-plating of fenders, nuts and bolts, etc. I wanted ONLY new parts so some details weren't absolutely correct (stamped HM300 pipes, non-wrinkle tank, 3 hole rear fender etc). I DID rechrome a double-cut front fender and correct early rims, and lathed a smooth oil filter housing.
   It all came together in Spring 2004. All 3 bikes were done, and the candy gold sandcast took 1st Place at Mid-Ohio VMD 2004. The toughest part of all was starting the blue-green sandcast; it was soooo new, I was chicken to add gas and oil and get dirty carbon in the new pipes! Eventualy I did, the day it was traded.
   I put close to 10,000 miles on the gold bike during the past 3 years and was my daily rider (until a certain Yoshimura cafe-racer caught my attention this Spring), so they're not all trailer-queens!

you suck. ;) that basically represents every collector's dream on this board.
bastard! ;)
at least there's a a ding in the blue tank and its left front turn signal can't quite "get it up"
small consolation for such a fine stable of bikes!
very well done 736, simply amazing.

Nope, thats not a ding, just a skylight reflection; that blue-green bike was literally always handled w/ white gloves. Didn't even have wax on it. It got a little dusty but thats about it.
I've been doing this stuff for a dozen years and have restored/owned 43 early CB750's. I've cut back lately but here will always be 1 or 2 in my garage.

736, you want a 40yr old kid to adopt ?
I can sweep & keep things clean, I'm toilet trained and don't make much noise....

Beautiful bikes.
Yep, I'm the kid that figured out how to put things back together...eventually.
