I don't know about that, Will. Say the pc was running all this time and usually the pc is bulletproof on most that have them running on their bikes, say. Starts right up, runs the rpm limit. I don't see a ground problem. Now comes the VP into the picture. You figure they use close to the same chemical makeup as the more higher rated; you'd think? So that more or less is to me, a chemical reaction of say that crap laying on the bottom of a caliper, not having the oil changed enough? That more or less locks the quad ring with it settling under the rubber and in its groove to push up on the piston and lock it. That kind of chemRe.
Usually the pc is a no run, rather than plugs misfiring... if the OP can determine that rather than the pc acting up. And since you are guessing back and forth, I'd more agree on the injector side than the pc side. That's where the chemRe comes back in play and using the cleaner at the nozzle holes, it may have built up there on the dry side of the holes. You know, when the vale is open on a dead engine, that's open to atmosphere in a faster evap. That could chemically dry that fast, crystallize that fast and close off the hole even just a hairline or a pie cut like a mountain ridge. Now act the incredible shrinking man, look at the circle, see how much square is in the micro; it closed that circle down. How much did not have time to take that space up and bleed out that pie cut.
So the less fuel the less flame front the hit and miss = Fire.
Make sense in the chemRe dept? ... IF it was the VP + injector + plugs?
Bike starts right up and idles? Yes = Not plugs per say.
