1998 Polaris Indy 500

Hi, I have just bought a new sled. it is a 1998 Indy 500. It has 3000 miles on it and is in mint condition cowl has barely any scratches and seat has no rips. Runs great and sound. But i have not yet had a chance to take it out because of the lack of snow. Which is reasonable i guess considering im in NY and its only novemeber. But i was wondering if this sled is supposed to be somewhat fast and what u think it will top out as. And most of all if it will be realiable for me. And if there is any problems I have to look out for.
Thanks,
Dan

As far as i know these sleds are very reliable, just bought one myself ... Not really sure on the top end though, id say maybe 95 for a 1998?

indy 500

If i remember correctly it tops out at about 85 on the speedo, if you change the main getting to 290's from the 350's factory jets, hang on.

Jetting

The early 500's all had around 300 or lower main jets, when polaris started to shell out warranty money they increased the getting so as not to melt pistons since all sleds are not ridden at the same altitude/temperature, it was up to the rider to to determine the correct jets for max performance, my 1997 indy 500 had 280's and ran like a bear, the sled was ridden just south or Buffalo NY and i had no problems, plugs were a light brown. just my experience, good luck

Polaris Indy 500's are great. Lots of parts for them out there, reliability and all the fast one needs. I have 2 of them + a parts sled. My '98 will go 100mph or so and the '91 will go around 85. My family & I just usually cruise the trails with them though. The only complaint is that they're relatively heavy but they're trail sleds. They're built well.

From what I've been reading, they ran fatter jets in the '97+ Indy 500s to compensate for oxygenated fuel. I suppose if a guy were to run the absolute best of the best non-oxygenated premium gasoline, then stepping the jets down some could pick up some power.
For me, I'd rather be safe than sorry.

I haven't ridden my '97 yet either, but I'm really looking forward to it, and if 85 MPH is realistic, that's all the faster I'm going to want to go anyways.
I looked at tons of different sleds, and finally decided on a late '90s Indy 500 for the simple reason is they seem to be incredibly reliable. That's the most important aspect of a trail sled for me. I don't care if it's super fast, or draws the most attention sitting in front of the bar. That's not why I ride. If I want to turn heads at the bar, then I'll bring out the old '73 Sno-Jet SST 440 that's fully restored and let 'em stare at that. (if I can keep the old turd running that long, that is. It likes to eat points and plugs.)

I think you'll be real happy with your '98. I'm very glad I got my '97.

Happy trails!

Last year I held my 1990 Indy 500 tapped out for over a mile on a lake and barely saw 92 on the gauge. I would say around 85 is realistic.

I have a 97 Indy 500 SKS and it tops out just over 100 mph pinned on the straight away.

I have 2indys a 93 classic touring 500 L/C. And a 97 500 fan, both have 488's.
The 97 is great, 5000 miles and fly's. no problems. The 93 is real nice too, it's L/C .
The only thing with the 93 indy is that if the temp is above 32 degrees out, it overheats. Notreal bad , but I have to stop and throw snow on the heat exchangers. Drag!
This is because the heat exchangers are under the footboards! The snow don' t hit them and the air ain't cold enough to cool them! What a place to put them! But when it's cold out, Watchout! Goes real good! Back to the 97 indy I have gotten 80 mph out of mine, It would have wen't faster but , not me!
You bought a good sled, Enjoy!

Yea when i went to get on my sled yesterday i looked to see what it was and 63 K is not a whole lot of speed, I put new rings and pistons and honed the walls, New coil and plug caps and it still seems like it blows plugs, One burns fine the other burns the tip white if im hard on it. Would'nt mind some tips if anyone has some.
