Question Question for someone plez

just picked myself up a arctic 98 cat zf 600 and have a question that someone might be able to answer.

i just couldnt wait till we got snow to try this sled out so i tried it in the yard a bit ....

i let it warm up for awhile (5 mins) and idel was perfect, a bit smokey but i figure maybe thats normal not being ran for awhile....
after that i took it for a spin... noticing right away that it was reving high 4-5k RPM to get it to take off.... but maybe this is normal ...
i drove it in a bit of long grass and stopped for a second then tried to take off again but it would jus rev out and and the track would not move, i got off the sled and tried giving it some gas and it moved then shortly after the same thing again so i poped the hood and looked to see if the belt was spining when it was rev'd up but it wasnt....

my buddy would lift the sled for me and when i gave it gas it would spin the track no problem and fast if we wanted

i decided to put it away and come talk to some ppl about what this could be,

is it because it was on grass and is not made for that? or something else?
any input would be awesome

Yes it does take rpm to move a sled on grass. But still should go.
That smoke you see. My geuss here is 1 plug is fouling out.

It will smoke alot till it gets colder due to jetting. Thier jetted for temps 32f and lower, in-turn their running rich till then and will clear up...and foul plugs
That sled engages around 4200-4500..and no lube to slide on.."ski's" , + maybe dirty clutch..sticking and it could take 5k to move it.

Smell anything other then 2 stroke smoke during this?..plastic, metal.
Hyfax's will weld themselves to the track clips if heated up enough and dry.
Parking brake on ? or has been on?...pads can be stuck and dragging.

Do you know if the sled has any clutch modifications? the RPMS's your talking about arent far off of what it should be engaging at but if any clutch engagment work has been done you wont know if something is sticking until your able to really open it up on a safe open space and get everything moving.

Clutches that sit awhile will sometimes not engage properly until you really open them up. This has happened on a few sleds I have picked up, a spin around the grass may not be enough to get that worked out. You can also take a mallet to the secondary and tap it (lightly) to try and get it moving (i have seen this work)

Just my 2 cents
