i'm guessing here but guy told me that 97 XLT has a 21-39.I dunno if thats even right but if anyone else reads this can you help me with what gears the standard 97 XLT has
hi! SNorat. Nothing else is wrong. I have already posted about this problem. People helped me but we didnt find a problem. Clutch is ok, driven ok, carbs ok, compression ok Track ok. The only thing im not sure is about the gearing. If i remember well, my dealer said to me that i have a 22/41 gear ratio and i see that all XLT have a 21/39. What is the effect of this??? Is my sled can just reach no more than 85mph with 34mm carb

Dont think so.....
22/41 gear ratio is 1.863 and a 21/39 gear ratio is 1.857 so their is not much of a dif in ratio actually the 22/41 should be just as fast or faster since Polaris like to over gear their sleds any way ,also with the bigger gears you will have less parasitic lose of hp since it is easier to pull a chain over a bigger gear than a smaller gear. so I think you have a problem else wear. Wear do you live ? If you are close enough I can maybe help you out better.
Re Snorat..
Thx for your Help. Well i live in Quebec..probably far away from you eheh. Well can you tell me with no doubt that this 98 XLT Limited with Xtra 12 and 34 mm can go faster than 85mph??? I have asked this question to people and they said yes but why i cant

? why

? Like i said this Sled was serviced 3 times for trying to find something wrong. So if you said that the gear ratio is good, well im frustrated... Do you have a solution Sno?

i Forgot this , compression is 115 in each cylinders, maybe a little low??? A friend of mine said to me to try sanding the clutch cuz maybe i have belt slippage but my two clutch arent hot after a ride, just the Belt.....(sorry for my bad english im french)

I', working on a solution but I have to ask,how far are the clutches shifting out after a ful throttle run and what are your topend rpms also does it have a clutch kit in it or has somebody done any clutching to it.
Too check the first question run a marker line from the outer edge of the clutch down to the shaft on one of the sheaves and take it for a rip after your run look to see how much of the line is left on the clutch.

Hi Snorat!!! Again, thx for your help guys...
When i first bought this sled, he had a clutch kit on it and i was reaching 85 mph but on a long distance. I have put back the Stock clutch kit cuz i was thinking the speed problem was this. With the stock clutch, my speed is the same except i reach 85 mph more quickly. The mark on the clutch is worn off except 1/4 inch. My RPM is 8000. Clutch, driven Clutch and Carbs is all stock.
I have try to losen the Track as much as possible but not better... I have try yesterday another Spring in my primary Clutch for have a little more RPM (about 8100) but no results. Trying to Change Preload on the Driven Clutch Spring without any change on the top speed

This sled is not considered a high perf machine,it is considered a trail cruiser that is why it has the smaller carbs for gas milage also the xtra 12 will slow them down.I'm not sure but I think you should be pulling more rpm such as 8500 to 8700 top end.what is the secondary have for a helix in it and what spring is in it? You say the carbs are fine did you have the needles and seats checked as a leaking needle and seat will give it toomuch fuel and you will see a lose of speed.
What kind of asessories are on this sled.
Also soften the suspension up a bit and let it sag with you on it this can also help.
The xlt special with the x12 was not too much faster at around 95 to 100 on the speedo and the special had the high port motor with the 38 carbs and a bit higher compression.
If I can think of anything else I will let you know.
ps try tightening up the secondary spring to the next hole this might help some also droping 1 tooth on the top gear might help you get into the overdrive of the clutch as you are only getting into a 1to1 ratio

The Helix is an 32 angle and the spring is Stock. This Sled dont have accessories like reverse. I have try what you said about the suspension. Is the Front Strap limiter can cuz this problem if not properly adjusted??? I have already tried different hole on the secondary spring...
The Limited and Special are Liquid Cooled Piston Port. The only thing different is the 38mm Carbs

The dif is in the port hight as the limited is the low port which is better for bottomend for trail cruising and the special is the same as the 97 xc 600 which is a high port for better top hp both are piston port.If you are willing to spend some money get it ported and go with the 38 carbs with the special specs also billet heads for pump fuel to boost compression a bit.Also I perfered the t11 helix on this motor as it would pull harder on the bottom and still have close to the same shift on top end and also run the light blue spring in the primary not the gold or the dark blue.I will check my manuel to see what the operating rpm should be for this machine because I think it is to low.
Will keep you posted.

RE Sno. Thx for the precision about the engine. Im already use a Blue Spring in the primary Clutch. I have put this spring Monday. I have adding about 100 RPM.
Well, the conclusion its that this Sled can't go faster. I know that i can put money on it to have better performance. The thing im frustrated its cuz people who claimed that they have Stock XLT limited, reach 90 to 95 mph and like you know, i cant. Who say the truth

I will not spend my time trying to find a problem if i dont have a problem

)) I have send several Email to people that sell her XLT on the net for trying to know what speed they reach. I hope i will have some answer tomorrow. Im very surprise that a Triple 600cc cannot reach 90 mph, really surprise, even if i have smaller carbs, hard to believe
Thx again for your Help SNo
