have a Boyer electronic ignition box fitted , a pair of new coils , plugs and leads. Also have now a new pair of Amal carbs.
the bike was running fine untill I decided to take it for a ride, then decided to go down on one cylinder.
If I lift the plug cap up and just rest it ontop of the right hand plug both cylinders fire fine, take off or push on to plug and it stops the cylinder firing. left hand side is fine.
anyone an idea what the problem is?
I suspected carbs as I have changed all electrics, it seems that the motor runs fine with a loose plug cap, would this be too much fuel and the loose plug cap generates a bigger spark???
confused
