I have just puton a set of psi pipes on my 97 xc.... the factory recommends to put in new needles and a few other things besides the jets..... what would you guys think? Do you think that jets are enough? they said 290s in it... I thinkI can go lower..... what should I look for when I test the jetting?... best way to do it? Do I need to do that everytime when it gets alittle warmer out?
I see alot of people test plugs when the weather is a little warm... is that something I should think about doing? Also... now when I start out with them on.. the sled is a little boggy but not bad... allready has a cluth kit in it... what might be the casue of that? Clutches bad? weights? helixs? I need alot of inputon this since iAm not going to take it to a dealer.. teh cheapest one is about 70 dollars a hour and iam sure I will get the shaft..... is anyone close to sandstone mn and wants to make alittle money?

Every sled and motor is different. The best thing you do is research. There are lots of books and web pages that have everything you're looking for. Some people say jet it more than others. But putting those psi pipes definately is going to require re jetting. You can do it man! Don't take it in, if you can read, you can do anything.

Contact PSI have them send you a jetting and clutching specs for your sled and there pipes. They may charge a few bucks but it's better than blow up.

I would check the PSI HSOforum for the jetting and clutching info. I've got SLP pipes on my 96 xcr and when I contacted SLP they were more than willing to get me the info I needed.

*important* check the plugs when it gets colder. The air is leaner and in turn you get less oil.

Don't let it intimidate you....I don't know the left from the right and I've never had problems being in the pipe market. Maybe check out the "Dial a jet" add ons. I've looked and if I wasn't getting close to retiring the 600 I'd invest.

I took my sled to a guy in Askov. I beleive his name was Tom Best. he lives nev to the water tower in town. I was happy with the work. He works out of his garage. You could probably look him up in the phone book.

on sleds you should check the plugs and keep track of performance with drastic weather changes because cold air is is more dence (spelling?) meaning that you get more air molicules so you need more fuel so you dont lean out your fuel ratio and seize the cyls. Most after market companys will be more than glad to help with jetting your sled is probably bogging because it is too lean with the new pipes
