Re: misfire??
if its doing it when cold i would say its more a fuel or spark plug issue.

Re: misfire??
Cheack the HT leads mate, my XJR400 had a misfire for the 2 years that i owned it, i always put it down to the valve oil seals leaking oil as is belched white/blue smoke when it fired up. I started it one day with the tank off and saw a bright blue spark jumping from one of the leads!

Re: misfire??
but the temp hasn't been anything like cold enough for the last week. And carb icing gets worse with engine running time.

Re: misfire??
its not just cold temps that can do it but yes, if it is carb icing it should get worse as the bike has been running longer.Northern ANdy wrote:but the temp hasn't been anything like cold enough for the last week. And carb icing gets worse with engine running time.
