Thanx Bill, I appreciate the help. I have set the pick up coil to the new spec back when it was first recommended to do so. One question about that pick up coil though is, do you know if it would allow a strong steady spark on one side and nothing at all on the other?It runs like it should on the left side and with the plug out of the bike laying on the head to check for spark one side has nice steady blue spark and the other side nothing at all, not even an occasional weak yellow one.
I have to say, with no spark on one side at all and good on the other I was sure it was the CDI.Especially when I swapped the wires and the problem didn't move meaning both coils are OK.Double checked that with the plugs out too.
