Can anyone help me. I am about to drag this sled soon. its an 04 mod 800 converted to the 05 mod system with the holes in the bumper for the ram air effect. Ive played on main jet alot of times but still seems to cut out after a few seconds of full throttle on the river. Has anyone ever had this problem. symtoms are. if i gun it from a dead stop it goes to 8000 rpm and after about 3-4 sec she starts to cut out / bog but if i gradually work myself up she wont go past 7000 rpm. ive tried pipe mods that someone sayed to grow 3mm on the stinger part of the pipes. ive tried venting the gas tannk more. more air flow , less air flow to the engine. different pumps.. also tried 2 pumps at once. needle seat mods.. and now i have no more idea's please someone help.....
