Jittery at low revs

[red98]

ht leads are sealed to the coils,if you need to replace them its new coils time (two on the fazer) the ends do go hard after a while so trimming the ends is a great tip,look at the plugs and check colour and condition and replace if need be,balancing carbs will give you an instant inprovement if they hav`nt been done for a while...if that lot dos`nt work try cleaning the carbs  .....let us know how you get on
