I have a 03 hayabusa with 40,000 miles on it. When it's cold if I gun the throttle it stutters and sounds like its trina cut off. But when its hot its runs fine. What could this be, I've already changed the spark plugs
Make sure you crank it cold with the fast idle on. Let it warm up a bit and turn the fast idle off. Nothing runs that great until it comes up to temp. My bike has always ran better in cooler weather. I've been told the air is more dense and makes the fuel charge so.
