Hello, has anyone had this problem, Bike working fine, next journey went on to three cylinders and has stayed that way every since.

Changed plugs, no differences. seems to be no 1 cylinder, pulling off HT lead no differences in tick over.

opened drain on no1 carb petrol present.

i am thinking it might be a blocked jet. Any thoughts suggestions, please drop me a line.

Thanks Gregski.

Hello and welcome.

I suspect that the HT lead to the plug has broken down thus not firing that plug. Take the plug out and ground it to the engine and turn the engine over to see if it sparks.

Hi there,

It could be that the HT lead has broken down but also that the coil itself has broken down on No 1 cylinder.Best way to check is if the HT leads are detatchable to swap the lead over with one that is working,if it still doesn't fire on No 1 then you know it is the coil that is duff
