I have a 1999 FZS600 I have owned it for 18 months and it is now on 70,000 miles. Recently it has developed a spluttering power delivery in low revs, typically below 2000rpm and usually when cold but it has happened a few times now when the engine is fully warmed up, which has prompted me to post here.
Since ownership i have always used standard 95 unleaded fuel. never had a problem. The bike starts usually first time, amazingly and tick over is fine, no problems with that. It is just really when pulling away, in first and in low revs in second gear in traffic, it seems very boggy and splutters until it gets up to 3000rpm. Not every time, but its happening more often now.
Where do i start to check for solutions to this issue? electrical or fuel related?
