my bike seems to hold it's rev's, when it get's down to around 2k,in 1st or 2nd gear i can ride along for a while with the bike going between 15/20 mph with no throttle,the throttle seems to return fine with no bother and the temp seems a little higher than normal but not to much, it also feel's like im riding it on choke and whines really loudly but that stops when i pull the clutch in. my bike is a 2012 model with 5 1/2 k miles on it if that makes any differance? any advice or where to start looking would ge great cheers
