Very bad running.

(1/7) > >>

Bradders:
Evening all,

Riding into work this afternoon when suddenly my bike loses power, runs very rough and noisy. It now won’t rev above 4,000 rpm and stalls anywhere near tickover. It’s all happened very suddenly and has up until now been running nicely. Any ideas where I should start looking and what might be wrong with it? Thanks in advance.

Sesman:
Start looking in gumtree..😁

Sesman:
Seriously though, start with fuel and move onto ignition?

K2-K6:
Start it from cold, run for 20 sec, check if all exhaust pipes are warm at the head.

If you've two cold, it's likely one of the ignition circuits, so which one's if that's the case.
