Hi, I've had my fairly standard bike for just over 2 years. Hardly used it really, one thing and another, you know how it is. Its covered around 20,000 miles, in reasonable condition. Problem - misfire/cough at low revs when moving slowly, mostly when in traffic. From closed throttle engine will almost die then cough back into life. On tickover it sometimes does it as well, last MOT the test engineer commented on it. Very unnerving. Ridden fast you don't notice anything. Its quite intermittent which is annoying. I have changed original relays, fuel filter, plugs and leads. I've read a lot about TPS in FAQ etc but not really sure this is the problem? Also vibration through the bars is severe until you get to about 75mph then smooths out - is this normal?
Many thanks
Andrew
