Ive got my bike running at last
After cleaning the plugs 3 times I decided to buy some new ones (£35).It fired up straight away.The guy in the bike shop said he was 99% certain it needed new plugs and he was right

I had a trouble with plugs on mine, plug number 4 fked up after 50 miles. Thankfully my bandit shared the same plug, swaped 1 over and it started up.
Some of the plugs might still be fine, carnt beleave just 1 dud plug stopped it all.
