I have the same problem with the same kind of machine. New plugs,new gas, carbs cleaned doesn't help. It's always good off the line, but is limited to 4400 rpm. Fuel pump is puting out good. Let me know what fixes yours please.watersports06 said:I own a 96 sl780 and cannot get my rpm over 4400 and is very sluggish out of the hole, sometimes it snaps out of the hole and sometimes its sluggish, it is got me baffled unless it is a limpmode that i dont know about, any help would be great.
