Spark Plug warning and a question
Despite the negative posts that I saw on other HD forums, decided to splurge on a set of Pulstar plugs for my old girl. Been running fine, if not noticebly better until yesterday. Suddenly am running on one cylinder. Limped home (only 1/2 mile away), switched plugs, and indeed found other cylinder not firing.
Put in a set of new Champions and am back in business.
The Pulstars are going back to JP Cycles for credit if I can ever get Customer Support to respond.
The question: is it beneficial (for longevity, not performance) to run a 1-step cooler plug in the rear cylinder?

I'd say put the same Champion plugs in both cylinders and run the heck out it.
As for the Pulstar plugs, did J&P recommend those plugs to you or did you just decide to give them a try? My guess is the latter, in which case I'd just eat the cost of the plugs and write it off to experience.

Were you not in class for the "splitfire" class??
Champions are about the only plug that can really recover from oil fouling for me anyway. I use them in older machines, and In [otherpeoples] shovels with Drag Pipes.
My Shovel gets autolites...

Your old system as far as voltage probably did not have the voltage to keep them clean. Just keep up with the cheapest that works and keep a extra set on hand. Sure they work for some. Least give them warm cuddly fillings. Just considered it a lesson learned. If it sparks, it burns. A bigger spark does nothing. If it doesn't spark, you know it on a twin..HA.. Throw them away. Not JP's fault.

Just took 4 out of a 2005 CR-V with 104K and a 2007 Honda Civic with 112K. They would have gone another 100K if not the life of the motor.
