Of course I didn't leave it until tomorrow
I found out why no fuel was getting through, the fuel pump is seized. So, in goes a new one, back in the tank, back on the bike and...... It primes
(I thought that the priming was quiet on the other one)
I just need to wait for the battery to charge to see if the bike fires. I managed to flatten the battery with the constant on and off whilst working out the ignition wiring.
