To be honest, it's never occurred to me to feel my coil after a ride. What prompted you to?
I had a earlier K100 coil i use on my R65LS,i managed to get the later version with the brown lead connectors,but it get's hot!!!the one i was using was the older,but much larger black type,nothing wrong with it,i just changed it over,and noticed the heat!!the black one gave a reading of 2.0ohm,the new one 1.9ohm,both work fine,i think you don't want to go lower then 1.5ohm,but higher is ok with the electronic ignitionJulian.
