Hi. First post here. I just bought a 2002 Katana 600 and I figured since its oil cooled it takes a bit longer to warm up. But it will stall out on me unless its up to operating temp. Usually around 15 mins. Keep in mind its a bit cold here in PA right now. I ride in anything over 30 and it's been about 40-50 degrees since I've been riding. Does this sound normal or maybe a problem with my coolant? Any help is appreciated. Thanks Guys.
