G'day fellas, took the bike for a lap around the block the other day but number 4 cylinder wasn't firing. when it started it seemed ok but down the road it started to miss and then nothing at all. I checked fuel but that was ok, but when i removed the plug to check for spark there was a weak spark and then none.
Where should i check next?
Cheers

Swap leads one and four over,if four fires then but not one,prob means its your ht lead or plug cap faulty..Cheers Paul J

Thanks Paul, but if i swap leads over would it cause the firing order to be out?

1-4 & 2-3 fire together, so it will run OK
Spark plugs are much more sensitive these days so might be worth looking there as well
