Just fitted Hondaman electronic ignition and during the initial points/timing setup prior to connecting the system, left the ignition on by mistake while I went in for lunch. After fitting and the initial ride, all was well - big improvement at tickover and low down power. However, on the ride back home, I noticed that the bike was missing very slightly at tickover. When home, issolated the miss to number 1 cylinder (could feel the 'miss' when putting hand over silencer). Reverted to standard points system, no change. Put electronic ignition back on and changed plug, suppressor cap and checked all coil LT wires around the coils but still no change.
Remembering leaving the ignition on and having had bad experience with aftermarket coils previously (coils on the bike are aftermarket), although a duff coil should affect 1 and 4 cylinders, wondered if the coil could go down internally on one of the HT circuits as a result of leaving the ignition on for half an hour or so. Changed coils to spare set of standard coils (that I reconned using Ash's coil fix method) tonight and miss appears to be solved. (when running in the garage tonight anyway).
Question for the electrickery experts (for my peace of mind) - can a coil go down on one HT circuit internally as a result of leaving ignition on?
Thanks in advance
