95 polaris engine runs but the track wont spin - Snowmobile Forum: Your #1 Snowmobile Forum

i have a 95 polaris indy 500. it ran good for a year. then i took it to full throttle repair to get it looked at because it only started with starting fluid, when i got the sled back they told me it had excellent compression, and that it needed a needed a head gasket and a fuel pump.so i brought it home started it up(to make sure it wasn't worse when i got it back) and i got it started but the track wouldn't move. so i called them and they told me it wasn't getting enough fuel. so i replaced the fuel pump and head gasket. the engine runs great now.(still have to start it with starting fluid tho). the track still doesn't spin unless i pick it up odd the ground. and even then it spins very slow when the engine is running at full power. any suggestions?

Things to check...

worn belt, sticky/dirty primary clutch, broken spring in secondary clutch, belt deflection too great. I would consider the drive train if the engine is running great. Rule out those things, then consider cleaning the carbs. Lots of times, plugged jets in the carbs won't allow the engine to make power.

thanks the belt is new the carbs were just cleaned and the clutches are very clean. i will check the other things.

Does it bog or anything of that nature? Or run the motor while it idols and feel the exhaust pipes and see if one is warmer then the other and that will determine if its running on both cylinders.

both cylinders do fire. i have dual exhaust and both pipes get warm/hot

with the back of the sled propped up and the engine off, is the track easy to turn by hand?

bonecracker9300 · 12-01-2012, 11:49 AM

no its not easy to turn it tacks a little bit of muscle. the belt has no wear on it. when i turn it on and its proped up the track spins fine when i give it gas. but it wont go when its on the gound

And the the track looks to be in line with everything?

joshkidner · 12-01-2012, 12:18 PM

pump grease into all fittings. there (i believe) is a fitting under the secondary that goes to the jackshaft. make shuretrack is aligned and not too tight. all of this is on youtube do your research!

i did my reaserch lol. it was the clutch i hit it with a hammer a few times and the cutch was stuck not opening up properly. but its all good now. thanks every1. 1 other thing tho. i have a dual exhaust so each cylinder has its own pipe both pipes were getting to the same hottness when i ran it but just now i had it idle for 15 minutes or so and one pipe is hot the other is cold but the is exhaust coming out of both pipes. ohh and yes the track is in line.

One is warmer then the other after 15 minutes of running? They both should be close to the same temp or at the same temp. Check plugs/clean carbs.

bonecracker9300 · 12-01-2012, 08:57 PM

the plugs are band new. and the carbs were cleaned professionaly buy full throttle repair. but the way its running makes me doubt there proffesionalism

There was just a post on here a guy put up and had some kind of problem and he took his carbs in to have cleaned and it came down to his carbs not so clean after he took them in.

and I was the one that kept telling him to clean the carbs!

So clean your carbs, jets, etc. Adjust carbs propertly...

Can you turn the track by hand or spin the secondary by hand?

scrammy650 · 12-01-2012, 10:05 PM

make shure to clean clutch all the way just not a little spray or may do again

ben.simons · 12-28-2012, 06:07 PM
