I have a 2000 gtx starts ok runs out very well but has a low speed sputter, replaced plugs and fuel filter still same problem. I took it to locale dealer to clean carbs and tune.They checked fuel lines and vacuum lines said all that was fine, took 4 weeks. They then told me that the only other thing it could be is the crank shaft seal leaking and that it can not be replaced and I need a new motor. the ski has 60 orginal hours and was always garage kept.
any ideas.
