Triumph corporate is very hush hush about the CDIs. Go figure. If we knew why different model CDIs were spec'd we would know the hush hush. What ever the hush hush is, it appears to be so ridiculous that the gag order on divulging the hush hush, is to some, nauseating.
Have you verified the pick-up coil gap, said pick-up coil residing under your right engine cover? To me that is the only variable left.
btw, my itty bitty blue dial is set to position '4'.
