2007 YZF600R won't idle. This bike has low miles(1,785). I've tried running both 87 octane and 91 octane. In my opinion, this bike has always idled rough. This motorcycle was bought new. I've tried taking it back to the dealer several times. They tell me to keep riding it. It will smooth out. Also, they gave me some Yamaha ring free fuel treatment to put in the gas tank. The bike will idle around 600rpm but it's barley running. When I try to turn the idling adjustment screw up it stalls. The bike runs smooth at highway speeds except for an occasional backfire. I've had the bike serviced once since I bought it. I guess I need to take it back to the dealer, now that it is out of warranty and pay 400-500 bucks to get this problem fixed....
