My 04 plate MZ1000S has recently developed an irritating misfire below 3,500 rpm - above that it's fine. Low speed running is lumpy and occasionally the engine cuts out completely. I first thought it might be dodgy fuel, but it's gone on for too long - I have checked the air filter and changed the spark plugs to no avail. I've read of possible coil issues elsewhere, but otherwise a bit stumped - anyone else had the same thing?
Oh, and it's Friday 13th, so the gear linkage decided to undo itself 50 miles from home - bodge job to get home!
