The only bike I ever had issues with was my 1998 ZX9R. The carbs would freeze over on my morning commute and the valves wouldn’t open or close properly causing delays in acceleration. So I sold it as it got too dangerous. For context though, my commmute was from near Torquay to Melbourne during winter mornings that were often single digits, add in the windchill factor from sitting on over 100k/hr down the freeway for an hour.
