I never thought the GB500 looked just quite right from the front... All the right elements were there but they just didn't seem to come together properly. The headlight is maybe a bit too big a...

The GB came with the original chain and sprockets when I bought it. The sprockets were in ok shape but the chain was 24 years old and had close to 10000 miles on it so I decided to change it out. It w...

I thought these were a good deal for $120.00... nice machined aluminum, sturdy fittings, quality fasteners. The package finally turned up and it only contained one mirror. There was no mistake... they...

The GB601 is finished.... for now. I gave it a wash and wax and detail and spent a bit of time riding it. It's a lot of fun and makes a great sound. It will definitely draw a crowd on bike nights. Can...

This is something I've done on almost every motorcycle I've owned: braided stainless brake lines. It's a cheap upgrade that's easy to install, gives a noticeable improvement in braking feel, and looks...

I got tired of pissing around with the round slide carb that came installed on the GB. It wasn't jetted properly, it didn't have the right cables, and it wasn't the right setup for this engine. I stil...

The results of the first outing showed the following: The clutch behaves inadequately. As I suspected, the release bearing with NC-30 doesn't fit the 21-24 engine, it's too long. I had to temporarily...

I thought I'd install them and forget about it, but nope, turns out the exhaust flanges on the 21 motor are tilted differently than on the NC-30. Had to bend them again, try fitting them like 20 times...

I bought a 41mm Mikuni flat slide carb kit which has a plunger choke right on the carb. That meant the cable choke and its handlebar mounted lever had to go. I picked up a salvage CBR1100XX switch blo...

Then, problems with the electrics began, as the order of the cylinder operations was different. I ordered an NC-24 ECU from China; the prices for them at the scrapyards were outrageous, but this one w...

On my first attempt to install the head I busted a bolt. The original ones were stretched and brittle. On the advice of a friend I bit the bullet and ordered new OEM bolts. This set me back about 2 we...

Almost the Final Step in Restoring the NC30 While assembling the engine, I didn't notice the differences in the shafts where the clutch is mounted. Naturally, I started fitting the clutch basket from...

  New cylinder and piston bolted in with a generous amount of oil used to assemble....

I also serviced the front fork, filled the forks with ENI 10W, overhauled the steering, and tightened it....

I had a bit of free time today to mess around with the GB so I thought I'd tackle a relatively easy job. I bought the Barnett clutch springs when I got the piston kit and carb. They are a recommended...

Sprayed the head gaskets with a special spray....

I just got my cylinder back from Harley Davidson of Calgary with the new 101mm sleeve installed and honed. As soon as the cylinder head is finished it will all go back together..... hopefully soon!&n...

Gathered up The NC21/24 one-way clutch arrived....

I've decided to publish my blog in short parts for your convenience. I think it would be boring to read a restoration blog the size of "War and Peace" :) Measured the oil clearances of the main and c...

I posted earlier that one of the studs where the seat hinge bolts to the frame was broken off when I got the bike. I drilled it out, found a suitable bolt and tapped some threads into the hole. Probl...
