Hi all, today i picked up my bike from the garage...but when i picked it up, the mechanic told my that either the coils are on the way out or cards need doing. I have done about 30 miles today in the sun but tonight (and its chilly out) It started popping/back firing and juddering. If i put into neutral and rev, no pops or anything. I didn't get far enough for the engine to get even warm...just a few hundred yards lol. I have noticed (before the garage) for a while that when stationary ie at lights, the bike revs almost stalls and sometimes does cut out and the mechanic who has just replaced the exhaust system, whilst taking it for a spin noticed the same thing and suggested either coils or carbs. First are the symptoms I have described that of a coil failing in style? Or possibly carbs?? I am a novice when it comes the mechanics of things but would appreciate and advice
