Was out riding with the boys today, and teaching a mate who just got his first bike, how to slow ride in the carpark. Everything was great, but one thing I don't really feel to sure about is how my bike behaves sometimes...here's the go: The bikes all nice and warm, but when I am just sitting with it idling and give the throttle a bit of a quick blip, the engine revs up quickly, but then after the throttle is let go, the revs drop down below idle, then slowly make there way back up to 1500 or so rpm, wherever the idle speed is. I don't know if it's a compressionp problem - which means a shit run-in on my account, or an ECU problem, as mine has all these new mod cons like EFI and Electronic Throttle Positiion Monitoring, instead of the older "fly-by-wire" which I find to be more accurate IMHO. Is it just a case of kawasaki having the bike tuned like this? If so, a PC III should sort this out right? If not, well, I am stumped, as my mates R6 doesn't drop below idle then back up after he's given his a small blip like I do...I am really puzzled by this...Anyone else had this problem?
