hey guys i own a 2001 xc sp 500 and have a small problem. after i start the sled up and let it warm up, i hit the throttle and the sled seems to hesitate and almost burp. now if i pump the throttle the sled takes off like a champ. i am thinking that it could have some thing to do with the variable exhaust because i put new plugs in it and there was no change any ideas? if you guys do think its the exhaust could you please inform me on how to set it up correctly, as a matter of fact even if it isn t and you know how to set it up can you fill me in anyway, thanks guys

I'll just ask a question or two, when was the last time you cleaned your VES system and also have you cleaned your carbs recently? Are you running with old fuel? Process of elimination......

i cleaned both 2 weeks ago but i am running fuel from last year which was stabilized

DONT PUT ANYTHING IN YOUR GAS! If the high octane gas is put in and you nail the throttle first thing, it going to flood and it's too much for the engine. Thats why you need to pump the throttle with high octane. Simple

can you explain more paul

Drain your carbs, drain your tank, and start with fresh gas. Its the cheapest and most common repair. Its a good place to start.

Paul- On some sleds thats easier said than done. I put stabilzer in and have never had a problem.

On my sled i notice quite a bit of difference in the stabilized gas in comparison to the fresh gas. The stabilizer does its job to keep everything clean and moving freely while in storage. But the gas doesnt burn as well after it sits for a long period of time no matter if stabilizer was used or not. The only purpose of stabilizer is to keep the carbs from gumming up, not to keep the fuel "fresh".

After i burn that stabilized tank of gas out of my sled, it runs much better. I would be willing to bet that once you burn that first tank of gas outta the tank and refill you will be pretty happy.

Polaris is my way out - Other people just use a door.

The VES sleds have a throttle position sensor on them. If it is not the gas I would take it back to the dealer and have them look at the TPS to see if it is set up properly.
