HI All I am new to this so apolgoies if anything appears incorrect! We have the above motorcycle which misfires intermittently and gets better the hotter the bike gets. Its a single misfire and quickly redeems it self. I have ruled out poor fuel flow, carb issues, spark plug, ht lead and cap along with dodgy lanyard. Could it be the coil? If so, what method do you use to check it? Thanks for reading and all information greatly appreciated
