hey, im new to bikes so i thaught i would ask a question, i bought a bike a week ago, its a 1998 kawasaki zx-6r w/ 25000 km's when the guy started it from who i bought it from it started fine, but now that i go to start it it wont turn over, its really cold outside i thaught that might have something to do with it... but im not sure, thanks
