Hey guys and gals, I've been away for a bit!
I've started having some serious issues with my baby lately, rampant overheating ( flushed once a year since I've owned it in 2010) the radiator has been cleaned and I verified it with my boroscope, cut the thermostat ( restricted opening but still open constantly) warmup time was extended by maybe a minute but still it gets hot sitting in traffic. Water pump is clean and clear, inlet and outlet temps drop through the radiator, upper and lower hoses. Fan comes on when commanded by the ecu and by my manual switch.
Onto my idle issue, started Sunday, starts up just fine, idles at 1310 just like it's done for the last 55,000 miles. Within 1/2 mile the idle is up to 3,000 and no way of getting it down. Twisting the throttle back drops it 500 rpms. Tps reads exactly 15 at idle (doesn't change when I twist the throttle back) and goes to 100% at WOT. The bike seems to ride fine, no hiccups in power, no stalling, cannot verify any change in fuel economy, no diag codes.
Both started within 2 weeks of each other and I haven't dug deep into the idle issue yet but I figured I'd start here for some brainstorming. Could a bad coolant temp sensor give the ecu implausible readings and its trying to warm the bike by idling up? Is there even a iac on these? Are there ohm specs for the coolant temp sensor? I have so little time to mess with it anymore but I need to make the time soon.
Thanks for reading ( I know it's long but I'm thorough) cliff? Scott, anything?
