Indy500 bogs down over 25deg F - Snowmobile Forum: Your #1 Snowmobile Forum

My 97 indy 500 runs great around 20deg or below but when it is in the high 20s and it is warmed up it starts to bog down. If I cool the engine down with a little snow thrown on it, it picks right back up for a short period.If I can keep up a steady speed say 30mph it will not do this but trail riding with varying speeds it really acts up.

Any ideas?

Check how the plugs look. Sounds like it may be running too rich.

97 500,thats a fan cooled motor right?what seg said, plus make sure the fan belt is adjusted right and nothing is obstructing the fan. mice love those shrouds.

sounds like you have a cooling problem because it won't run right if its too warm and that explains that the faster you go cools down, because it will run like free air, chexk your fan and make sure othing in the wAY and that the belt is moving.

It is actually water cooled.

Is the water pump belt tight enough?
Is it still there? (not broken)

Sound like it could be crank seals have had the same symptoms on a current sled of mine
replace crank seals at it was fine

I'd highly suggest moving this into Polaris Snowmobile section. You will get more responses and ideas, although these guys are usually dead on. We should be paying them for their help... Hmm... Now that is an idea! Some of you would be very wealthy
