Sputtering Ski-Doo MXZ 600 SDI

It appears to drop to a very low idle and issues start at about 1:06

[@emphil1236]

if it doesnt stop it is your stator, the injectors run off the battery and not the stator so when your battery dies because the stator isnt charging it, it will sputter. I had the same issue

What spark plugs do you use? I have a 600 sdi and the manual calls for br9ecs which are always fouling. I also replaced boots and cleaned throttle body last winter. took it for one ride and fouled brand new br9's. I heard br8ecs is what I should run in my sled and I won't have fouling issues.

i no longer have this sled, but i believe the plugs i used were what the manual said. The plugs never fouled for me. I replaced the boots and reeds with boyesen's and cleaned throttle as well. think it helped, as it ran fine when I sold it.

Air leak bad gaskets or crank seal

Hmm. Strange. Idles at 2500 rev it up then goes down to 1100. And sputters.

Did u ever find out the problem my 06 is idling right at 2500 won't go down

[@spyd4r]

i *think* it was a combination of bad reed boots, dirty throttle and a bad battery.. i clean and fixed all those.. works a lot better

[@trentonmacaulay4589]

Throttle cabel ? My battery is good .got new boysen reeds coming so I'll try that next

[@spyd4r]

Trenton Macaulay throttle body was a mess inside of black rubber... you'll see it when you take the boots off
