The saga continues!
I have now replaced the relays, rectifier, starter button and neutral switch. The bike is now giving a nice healthy spark, but will only run for about 3 minutes. Stripped and cleaned the carbs yesterday, not had a chance to try it today, but will try and get a look tommorow.
We also checked for sticky valves, and all appears to be ok. Have rigged up an alternative fuel supply, and put an HT tester on the plug so we can check if the spark is staying strong. Hopefully this will give us conclusive proof of whether or not the engine is losing it's spark while running. There was dirt in the carbs, but nothing too excessive, may have been enough to clog the jets though. Also using fresh fuel to try it out.
Fingers crossed!
