We restore a pair of 1981 Honda CB750C Customs

Updated: Mar 27

A solid bike! Good bones, and a good running engine with good compression. We'll stay out of there and make it go, turn and stop perfectly, and look great doing it.

Typical of what you find when you start digging in. The brake pistons are toast and so are the lines and the master cylinder. As is nearly always the case a total brake system rebuild is going to be required.

Same with this steering head bearing, was centering as they do. We replace it with tapered roller bearings.

Our good-running engine is homely, and that won't do. so we extract it and mount it up to our engine stand, and after scrubbing and plugging and power washing, we will now soda blast it in preparation for paint.

Now we're all cleaned up and rinsed off and degreased and we're masking before we paint and bake the engine.

The details! Good badges, expensive and hard to find, we will restore these with careful repainting and TLC.

Likewise our valve cover will benefit from repainting.

Blast on! I looked like a powdered donut after soda blasting this engine, even with a healthy breeze that day.

We're repainted our frame and stands and cleaned and regreased the swingarm, installed some tasty new Ikon 7610 shocks. Time to put this thing back together.

So may mini projects - clean and derust the chrome fenders, clean the wiring harness and inspect and refurnish all the electrical components, and and and.

Rear hub brake lining was carefully renewed before re reassemble with new shoes.

Great seat and trim, old faded lettering. We'll repaint it!

Gotta have these raised white letter tires on these Customs.

We spend a lot of time making the electrics perfect, cleaning the harness, replacing glass fuses where we can with modern ATC, upgrading and checking the charging systems and starters. This stuff gets cruddy and causes problems if its not totally renewed.

ATC fuse holder has been inserted in place of the unobtanium fusible link. Coil power bypass feeds coil power through a relay, saving the switches and providing better, hotter spark, Details, details...

It's a roller! That fork has been vapor blasted and hand finished and the internals have been upgraded with the full RaceTech Gold Valve internals, a huge upgrade in damping and antidive. Brake rotors were reground and repainted, entire brake system is new, new Speigler braided steel lines.

Engine is reinstalled, so much more handsome, side covers polished and relettered and installed with new gaskets and seals, valves adjusted, new sparkplugs, and and and.

And holy smokes its done. Original exhaust was tidied up, carburetors fully rebuilt with OEM float valves and replated steel, gas tank and sidecovers repainted. Headed home!

Great pair of projects for a great customer, we have two nearly identical bikes to work with. One we're to do a slightly less involved project on, mostly a deep service, make it great to ride. The other is done frame-off, we repaint the frame and bodywork, the engine, rebuild the carburetors, upgrade the suspension, the works. Great bikes, and a super fun pair of projects.
