Went to take the bike out a few days ago to find the key sort of half in the ignition (must not have switched it off properly). Started Ok, quick run into town and it then refused to start at all - battery flat as a pancake.

Quick jump start off a friendly car (didn't have their engine running - literally just hooked it to the battery and started ASAP).

Got it back, took the seat off and stuck it on trickle charge for 24 hours.

Checked it and it fired up no problem.

Stuck the seat back on, left it for another few days and now it will turn and turn but not fire.

After a few turns there's a wee puff of fumes out the back of the exhaust.

Guessing it's not sparking? Anything else I could do to keep in mind before I go off DIY troubleshooting Oh Mighty Org?

Cheers
