Hi Mike,
A few years ago a few of us found that the ecu black cover was shorting
out to the westy rear seat hinge bolt. Problems seemed to develop on rough
roads or during turns to the right. Removing some metal where the cover can
touch the bolt, or other wise insulating the cover from the bolt solved this
problem.
Also try giving the ecu a rap or 2 with a screwdriver. If the ecu has
bad solder connections that will usually cause your problem to develop the
engine will usually stutter and continue on. The triumph adler ecu can
develop bad solder connection on the processor chip that cause your symptom.
Darrell
