I'll let nature go it's way ;D

There's still a lot of things to do though (chain guard and mudguard on the frame, front mud guard mounts, air filter, generator and electrics, rear brake, bash plate, ...). But I think I may be able to have a short ride this year at least.

The condition known as "new cylinder-itis" is a common sight on Bullet engines which have been tuned or otherwise modified, particularly where an iron barrel has replaced an alloy one, ASBO Bullets seem highly prone to this...

A package from HMC arrived and so I could work on reducing the speed by changing the secondary and primary sprockets:

A better view of the chain slider:

There's an obvious difference between the new and the standard primary sprocket:

The chain has a lot of slag, although ordered to specifications:

The adjuster bolt would just fall out with the tensioner in position:

So I took an M8 bolt and converted it to 5/16-BSC (and tried out my thread gauge):

This should work:

And also somethng handy for quick access:

And the provisional result:
