I can't afford to have it repaired by the nearest mechanics as they charge rediculas amounts, and the other mechanics is very busy for a month or so. So i'm going to try and do it myself if your brains can help me.
Anybody got any suggestions on how to sort it??
First thing to do is check you're getting a spark on all cylinders. Rough idling could be a number of factors, either fuel related, in the respect of the fuel itself, the carburettors, fuel pump, etc. Because it's running on at least 2 cylinders - it seems to be electrical related, and not necessarily fuel starvation.
Check for a spark first. No spark, and I'd look for loose electrical connection. Just checked my manual - this relates to the ignition coil, source coil and pulsar coil. In addition, check the connections to the CDI unit are in good condition.
