Tall Gearing
« on: 27.11. 2018 07:51 »
Got the seat back from the upholsterers and took the Super Rocket for an illegal tour of the neighbourhood. It goes very nicely and I am getting used to the considerable extra weight from my bitsa RE Bullet and the B44SS that I recently sold. What was noteable was the very tall gearing. It’s not out of order but there will certainly be some clutch work to do.

 What tranny are you running?

 RRT2 will do that in 1st & 2nd, 3rd is same all round, so the gap between 2 & 3 is closer and good for mountain windies

I’ll have to check it out. I assumed it was a standard box for the SR whatever that is. Where do the identification numbers find themselves?

A standard box will have 'STD' stamped on the inner cover just to the right of the clutch actuating lever, clearly visible.  If it's got anything different there is a BSA gearbox ratios data sheet  which tells you what internal gearing the various boxes have. Quite a few people prefer tall gearing and achieve this by fitting large engine and / or gearbox sprockets. It might be worth checking these too.

I’ve put the sprockets as per the parts book for the 1958 Super Rocket which are a lot taller than the ones it came with. The primary sprocket is 21 teeth and the gearbox 19 which were 18 and 17 when I got it which I presume was a set up for a chair, either that or towing a caravan.

It appears to be a standard box although Barry was obviously a little hung over when he put the letter punches to it
