I idle mine at about 1200 rpm cold and it climes to about 1300 to 1400 after warm up. rodhall -----Original Message----- From: Graham Rogers <[email protected]> To: [email protected] Sent: Wed, Feb 17, 2010 12:54 pm Subject: Re: [Nighthawk Lovers] starting problems If the seafoam doesn't work, I'd clean the carbs. My 650 and 750 both take about thee miles to warm up. The longer I let it warm up before riding, the better - sometimes longer than 6 minutes.
