Out for a ride today when the bike started to go on to one cylinder intermittently
Managed to limp home, but now come the investigation
The cylinder seemed to cut in one out when the bike rode over rough surfaces

So, what should I be checking?

Loose connnections seems like a good place to start

Which connnections and where?

Spark plugs and leads

Anything else that should be on the list?

Coil leads and earths is where I'd start

Loose negative battery connection gave me similar symptons once.

I now know its has no spark at the front cylinder

I now know its has no spark at the front cylinder

Front coil, swap them front to rear and see if the rear pot goes off! I assume you've tried a new plug?

[tony.mon]

Also swap plugs front to back, but not at the same time and the coil. Probably easier to do the plug first.

Sorted
Faffed about with coiles and plug leads
All working now
Thanks for your input
