TT500 won't fire...

[Wired1]

I went through it all again and then had the bright idea to remove the points and check them with a meter. This showed that despite looking clean and having the correct opening gap, they weren't actually making contact when shut. A bit of a clean with the fine sand paper and they work. I put it all back together as it was - there isn't any obvious markings for a standard position - and I got a spark!
Slapped it all back together and put the gas tank on and after three kicks she roared into life. I say roar - well look at custom exhaust below.
The bike hasn't been running for seven months and has been off the road for three or four years so I'm impressed.
The bike was a nice bike once but was stolen and recovered a year later - by which time it had been trashed.

Good to know it was an easy/cheap repair.

pour alcohol on it and strike a match (drink some first): it'll fire all right

If it looked like this maybe I would

My clymer manual arrived from ebay yesterday and includes a helpful fault-finding section. It suggested I clean the points... so it just goes to show that the first accessory you should buy for your bike is the workshop manual.
