Its a 100/90 19
1961 BSA Super Rocket Rebuild
- Thread starter Jerry Doe
- Start date
Don't forget, these tyres came out I think in the late1950s, and were also used as a " universal"
tyre for motorcycle combinations!
Tyres have come along way since then.

A quick update on the SR rebuild.
I have enough gearbox parts now to make one good gearbox. Been gathering parts from eBay. I have all new new gears and bearings. The layshaft runs on 2 bushes. The gearbox shell is away with Steve, a highly recommended machinist (more on Steve later). The layshaft needs grinding down. He will make undersized bushes to fit. The OD of the inner case bush needs to be wider as the inner cover is worn. Out of 4 inner covers purchased on eBay and the original, this was the one with least damage and easiest to fix. The 2 new layshaft bushes need to be line reamed and that will be done. As soon as I can pick up the gearbox shell and layshaft I am ready to put it together and in the bike.
I still have work to do on the wheels. I cannot believe how hard it is to find parts. Here are some general shots of where its at now:
The best and most exciting update is that Brent has finished with the paint and it looks great. I cannot wait to get it and to start installing things. Shipping this week.

It’s going to be a long time still. I have to go lock the tank up somewhere very safe. I have another BSA tank and will be sending it in a month or so.

Brent has just caused you a huge problem there Jerry…
The bar for the standard of the restoration has just been raised. No corner cutting or cost saving now, it’ll stand out like a sore thumb !

The BSA is gradually coming along.
The gearbox layshaft has been turned down and new bushes have been made at each end. All gears are new or s new condition. New mainshaft, etc etc. I am awaiting one bush to be made for layshaft first gear pinion. Then I can finish it up and put it in the bike.
I have been working on the rear brake. That has been a challenge. I can only find emgo shoes. They did not fit well, so lots of sanding to get the wheel to rotate smooth. Also I had to cut some bits of the emgo shoes at the cam as they were too wide. For the front brake I have very good NOS shoes. The rear brake turned out ok, I got a bit of stainless on it:

Things are moving along. The front end is completely rebuilt with eddy dowe dampers and progressive springs. I am using stainless oil seal holders. The front brake shoes are NOS floating shoes. I put the instruments on today and front brake cable. I will have my first gear layshaft pinion back early next week (had to have a custom bush made) and am then ready to finish putting the gearbox together and to get it in the bike.
I put the beautiful tank on for inspiration. Here are some pics from today:
