    Surge and low max revs

    Hi, I recently got a Tigershark as a second ski but it has 1 problem. I suspect its a fuelling problem and maybe a common thing. It accelerates well to 6300 rpm but immediately drops to 5500rpm and stays there at wide open throttle. Also surges severely at half and three quarter throttle.I cleaned the fuel filter but no improvement.Any Yammy riders got any ideas?

    I would replace the filter (assuming you can on that ski) then look at getting the carbs looked at. Sounds like a fuel flow problem. And no more WOT until you get it fixed unless you want to stick a piston.
