Hi,

Recently picked up two Norton jubilee 250s from my grandad's shed. They used to be my uncles and need complete rebuilds. I've done engine swaps and worked on bikes for a while, but i'm finding I'm having a few issues with these old bikes.

1- the manual is shocking. compared to a modern haynes manual that goes through each step, the one I was recommended has like one exploded diagram of the gearbox and then some notes on how to do it, same with the motor, clutch etc

Problem is, most of the parts are in boxes, unlabeled, and trying to decipher whats what is half the battle, then working out how it fits together, what goes in first etc etc etc.

The other big issues is where I'm going to get spare parts, seals, bearings etc etc

I'm aware these are the 'shiteweight' Nortons, probably the least desirable British bike ever made, but i still want to go through and rebuild them because they're my uncles.

If you can advise me please do.

Adam

Is this the manual you’re using? http://www.classicbike.biz/Norton/Repair/1960s/NortonRepair1960-1968.pdf

I wouldn’t say it’s worse than Haynes.

The 250 ignition timing must be 32 degrees, not 30 degrees.

The exploded diagram of the late gearbox shows a top hat piece reversed. See pages 44 and 33.

Do you have any photos Adam? I always had a liking for the lightweight 250 and 350 twins although never owened one.
