I have a 06 cabestany 290 and its no running properaly at at all. At low revs there is no power, will not tick over, and starts to die. Meduim to high revs better seams better but perhaps a little smoky.
I have had the carb off a number of times cleaned out every orifis with the airline. Checked float hieght, mixture screw all seam OK.
Please help as this is driving me made.
