RPM's hanging up/ lack of engine braking "Now w/ Video"
My 07 600rr has been having an issue of hanging up sometimes. more noticeable when its hotter out but it still doesn't do it all the time. no FI light. no modifications. 34K miles on it. suggestions? things to check or look for?

Reason: added videos
by hanging up i mean that i let off the throttle and the rpms stay about the same and very very slowly come down. and there is no engine braking at all. i've checked to see if the cable is binding and its not. if i pull in the clutch the rpms drop right back to idle, revs just fine. i can try to get a video of it if need be but its always kinda hit or miss. sometimes as it slowly comes back down i'll feel the engine braking kick in and out a bit like it'll kinda hiccup.
bike finally started doing it again yesterday and i was able to get a few videos. not the greatest vids but you can hear what the bike is doing and you can see the tach as well. i took 3 small vidoes. some show the problem better than others but heres the links.....any new ideas?
Well, engine braking works differently depending on the speed and the gear you're in. Yeah, the RPM's are hanging, but hard to know by how much without knowing the speed and gear, or if the gear ratio was changed.
ok well why is it that it only does it from time to time? like i sat in traffic yesterday and during down shifting and slowing and stopping it was doing it and engine braking was nonexsistent and then later that day doing the same exact thing it was fine? i understand that the amount of braking will be different but in the vidoes posted it is not there at all.

i'm gonna pull the tank hopefully this weekend and check all the hose's and the pair valve. i thought pair initially but then wasn't so sure because of it only doing it during hotter days. i'll let you guys know what i find
Well thought i had it fixed. tucked the PCIII wires up under the tank so that they were not picking up any voltage from ant power wires. Worked for about 4 rides worth and its back again. This time it happened when I stopped to fill up for gas.... then it went away once my fel level got down to about 3/4 full?!? No idea now. Help please.
i have the same issue, 06 600rr 25k km, does it in bad weather conditions only, (dusty, hot, humid, etc), after riding for at least half an hour
top speed becomes 110kph in sixth gear
stock, just slip on
i read on one of the threads that it cud hav to do with the tcp (throttle body) sensor
when on neutral, revving the engine at first would feel normal, but after a while rpm wud reach 10k nd then max at 7k
kill engine and switch bike on right after and it revs to 15k normally, which IMO could suggest that it is a sensor not a mechanical issue
bike is at a local bike shop, checking my injectors
i sent it to honda for service and they told me it was perfectly fine, idiots...
I am still having the issue from time to time and have not found a good solution yet. I was planning on doing a tear down here soon for maintenace again as i'm at about 45k now and want to check the valves again. I'm thinking i might block off the Pair system. There is NO FI light on at all when this happens but it really only happens during warmer days 75+ and its not every time but its a pretty regualr occurance. i've also noticed it sometimes happens after i'll restart the bike after running into a store real quick. sometimes it goes away on its own and others it just never goes away until after it fully cools down.
I resolved the issue by replacing the throttle body. Apparently the guy who had it before me messed with the fuel ratio screws on the throttle body. Inside each valve there is a screw that adjust the amount of fuel and air I believe and that jacked up the idle on the bike. After I replaced it, it has run like a champ for over a year!
