I have a 2018 800 rmk pro 1200 miles this season it has started to miss/bog. i can accelerate to 7000 rpm before it will miss, or in powder on a climb hard throttle it will miss---had a dealer change injectors,checked fuel pressure still has problem, compression is good new plugs, belt adjusted correct- am now thinking exaust valves--any comments thanks
2018 800 pro rmk bogging
- Thread starter LWILSON7
- Start date
thanks-- no codes but will check the ground, had a shop reprogram the valves
Thank-you, will check the stator assuming there is no repair for that just replace it.
Did you ever figure out what caused the bog / missfire my 2018 rmk 800 is doing 5he same thing
Replaced the fuel pump my self--no change-took it to a dealer who ran diagnostics said it was voltage regulator replaced it,I took it to the mountains -same problem it would cut out on a hard hill climb bogging between 7 and 8000. took it back they said it was the stator- replaced that-back to the mountain-no change-back to the dealer they said it was the computer-I told them to forget it! took my sled back- went to a recycler and tried a computer with a 30 day return policy. back to the mountain-no change still cutting out, returned computer. I completely unhooked all fuel lines from the fuel pump to the injectors and found one o-ring by the injectors that was not seating properly -repaired -back to the mountains -problem solved. I believe air was bleeding in which caused a vacume in the line, starving the machine under full load. If you Have similar problems start at the fuel system and maybe you'll save the cash and head-ache I went thru
Thank you.
