im new to watercraft and im having some issues with my sl650.
it smokes a lot.. maybe its just running to rich or bad piston ring? its very temperamental. it will run great for 5+ minutes but if you shut it off and try to run it again it has a hard time starting.
also, sometimes it will idle really well but if you give it gas it bogs down and eventually shuts off. It also idles really high. ive done all i can think of to adjust the idle screw and the throttle cable but it doesnt help.
Its hard because sometimes it runs fine but sometimes it acts up. if you have any ideas let me know!
