I'm curious of what that would be. I checked resistance and voltage with the following: resistance (on the bench) was at WOT was 3300; spec says 4000-6000 ohms. I couldn't get a voltage when installed with the bike running at 1900 rpm idle; spec says to set between .5X and .7x volts. Anyway, the bike runs fine throughout the rpm range with nothing unusual. Of course it pops a little when I close the throttle, but notihing beyond normal. Is there a default timing from the CDI if the TPS goes bad? If it is bad, and I'm running fine, am I just missing out on optimum perfomance through advanced timing at higher rpm?
