Hey guys i have a 2002 z 440 sno pro and i'm having some trouble with it. The sled will start and idle fine. When you give it gas it revs up to 5000 rpms and then the clutch kicks in but then the sled will bog down after 5 feet and wont go anywhere and just bogs and smokes. but when you have the track lifted up off the ground it will run fine and wont bog down. so it seems that weight is an issue. i don't know if its the clutch or what it is so if anyone can help me out that would be great!

Thanks in advance-Jordan

dosent sound like an engine problem, maybe its the belt is dropping to the bottom of the secondary to fast, maybe spring tension? just a thought.

Sounds like your oil pump went out and is dumping oil into the motor. I fixed a guys sled last year with the same problem. most likely the oil pump.

yea im gunna have to check that out. It doesnt sound right that it would be the oil pump though because it runs fine when the track is of the ground. but i dont know.. I dont want to spend money on something if its the wrong thing. ya know... but ill still check it out.

Thats what it was on the xc 600 i fixed. it did the same thing. at about 6k rpm it would just bog and smoke and it was spitting a gray liquid out the exhaust.

Also, the back shock on the sled needs rebuilt. Should i just get it rebuilt or are there any other options that arent to expensive that would make it better? Thanks guys

Price out rebuilding and see if you can find a used one on ebay, etc. for cheaper. Someone here will pop up shortly and probably give you a better answer.

Im guessing because its a sno pro that aftermarket shocks are going to be a little pricy. I could be wrong. Do a search on this site, theres been a lot of talk on here over the years about shock rebuilding companys and you should be able to find someone to do it fairly cheap.

In the minneapolis metro there are a few guys that advertise on CL for $20 or $25 for each Fox/Ryde FX rebuildable shock. If there are resevoirs, it is just a little bit more, usually like $35.

granted the guys on CL are "home-business" they just do it out of the garage. I have had no complaints with the guy that's close to me. If you take it to any sort of powersports dealership or repair shop it will cost quite a bit more
