A quick history lesson is in order:
About 3 years ago, Dyna-s ignitions began failing on an almost regular basis, maybe averaging 2 per month from Spring to Fall. Two cylinders would intermittently stop firing; in most cases, the bike would run fine when cold. Dyna more or less acknowledged they had gotten a bad bunch of parts, but as most of the units were out of warranty, that was of no help to those with failed units. These failed systems sort of gave E.I. in general a black eye around here, even though it was apparently a bad run of one system.
After all this had been going on for a year or two, a member here suggested to Pete that his proven E.I. system for XS650s could be applied to our bikes, and he adapted the Pamco to fit.
