I have an 02 Busa with about 25K miles. About 10 months ago I had a idle surging problem, bike would get a mind of it's own, idle would surge up to about 1800 and then back down, come and go. I had sourced it to a bad Inlet Air Temp sensor (or so I thought). Replaced it and the bike ran better than ever.
Last month, it started doing the same thing again. I checked the IAT sensor, even replaced it with a resistor to see if it had gone bad again but bike still had the problem. Usually happens after the bike has come up to temp. I have checked engine temp sensor, air press sensor, gear position switch, stator resistance, inlet air valve in air box, a few other sensors (I don't recall now), checked all the vacuum hoses / connections, used injector cleaner in the fuel tank and cleaned the throttle bodies. My model has no O2 sensor so that's not it.
Still no luck. I must be missing something really simple. Getting ready to take it to the local shop.
Did I miss something???
Thanks.
