When running at idle and low rpm in traffic or pulling away, my thundercat runs rough, splutters and has little power. It happens when the throttle is just cracked open. Once through this and opened up its fine. I believe it started when i left it standing over winter ( I put it down to petrol gone off) I have cleaned out carbs, checked sync, changed plugs and checked for air leaks, all to no avail. Has anyone had similar problems? Is there anything else I could try??

Thanks - rosie

Is the choke sticking?

It'd be interesting to find out. I have an FZR 600 with exactly the same problem which can be a pain in traffic
