    Hi folks,new member here from Ireland.Having an issue with my 1990 VFR750FL,no spark on No.2 cylinder.HT leads,plug caps&plugs are new,new battery fitted,etc.When the left&right hand coils are swapped over,the bike will run on all 4 cylinders with a healthy spark,however,when the coils are swapped back,the problem returns with no spark on cylinder 2.All electrical connections are clean&tight.

    Kind of at a loss over what's causing the problem,any suggestions/ideas would be very welcome.

    Many Thanks
    Irish VFR.

    Sorry for asking a potentially silly question, but why not just leave the coils swapped over, and enjoy life?

    Ciao,
