Hi! First, Sorry for my bad english im a french Canadian
...

I have just bought a used Sled. Its a Polaris XLT Limited 1998 my just 3000 Miles. The first Owner had put a Clutch Kit on It. Well, the performance was good between 0 to 50 mph but after, i need a very very long distance to reach 80mph (i can reach 85 mph with wind behind me). But my friend, with is POLARIS XLT 1994, stock, have a very good acceleration at low and high speed and reach 95 very easily far in front of me. Well i decided to put back the original kit and made it stock. But now, the acceleration at low speed is poor and i don't have more top speed. The acceleration at high speed is a little better but my friend is again in front of me.

    I was thinking it was a good deal with this snowmobile but im very disappointed with the performance. It is Normal ??? It is normal that a Stock 1994 XLT is very better than mine??? Can i make some adjustement???? Its not me that put back the original clutch kit, its was at the garage. Maybe they don'T have make the good adjustement??? What top speed i should reach???

Thanks guys for reading me

I could get 105 - 110 mph top speed on my 95 XLT, but that is running on very hard pack and ice.  if you are in a little snow, it will be a little slower.  Your snowmobile "should" be faster than the 1994, because I think they still had the 580cc motor that year.  Your 1998 has the 600cc motor.

Fortress,  Take your sled to a friend or a mechanic that you know and trust or a good dealer if you can find one, and get your sled tuned up.  Who knows what kind of shape the carbs,clutches etc are in after storage.  After sitting all summer the gas goes bad and gumms up the carbs which could blow a motor.  The clutches could be very dirty or the bushings could be worn out.  I had a 95 XCR and it could hit the 100 mph range, yours should too.  Find out what weights and spring are in the primary and what spring and helix are in the secondary.  Compare these to what your sled came with stock and go from there.  I think all you need is a little fine tunning and you will be happy.  Good Luck.

I think that in your first set up when you got the sled the guy had the secondary over tight and it wasn't shifting out.  Or you belt is worn and not as wide there for not going high in the primary and low in the secondary.  And the 580s I think were faster than the 600s in stock form any way.

the center to center clutch distance should be checked 12" on this model. it makes a big difference when it is out and it would be boggy out of the hole, with poor top end put the secondary clutch sounds like it is setup to much and the engine is loaded to much and cannot shift out to 1:1.

My two cents would be to start from scratch. Rip your carbs apart, make sure your carbs are clean, and are in synk.(crytical) Check the gearing! Maybe the guy who had it before geard it down. What kind of clutch kit do you have? (helix, springs, weights)? I run a 95 sks and I walk all over 700MXZ! If you really want that sled to rock, get rid of the stock exhaust! throw on some pipes. If your prepared to spend some cash you'll really get that sled rockin!

I have never ridden the 1998 XLT's in the gen II chassis but I did own a 1995 XLT and it was good for a little over 100mph on a good day. I raced a older XLT with the 580 engine and mine spanked it, so you should not have to watch that 580 blow by you if yours is running right. It is hard to say what is wrong with yours there are alot of possiblities. Have you had a compression check on the sled before?
