I have this 2002 Kawasaki Prairie 400 4x4 that will not go over 23-24 miles per hour. I have cleaned and gone trhough the carb 3 times and checked jetting and pilot screw and float height. I have checked the exhaust for blockage, checked the belt and clutchs and they are good, there is no drag on the wheels from brakes or anything like that. I did a leak down test and compression test and they were good. I changed the spark plug, checked valve clearance, I fixed the fuel valve and it operates properly now everything checks out. I am stumped what could be left something electrical? also to be sure does anyone know the stock main jet size and how many turns out the pilot screw should be on this Stock Prairie?

Any response would be greatly appreciated

 

anyone???? Anyone have a manual for this atv that I could get a few pages from or at least that you could tell me what the jetting should be and how many turns out the pilot screw should be?????????

 

this must not be a popular atv because no one seems to know anything about them. It is a pain to find a service manual for this as well. anyone have any suggestions for me?
