Help!!!!! Polaris sportsman 90 won't go foward but goes in reverse

[jasonlawrence]

Hi, I'm new to this forum and am in desperate need of help. I recently purchased a 05 polaris sportsman 90. The quads motor runs great. The quad will not accelerate forward. If it does its slow and will eventually pick up speed and then runs unbelievable. It has great power and torque in reverse but couldn't go over a twig in forward. I'm lost, any help would be greatly appreciated. The belt is in good condition and the and drained the trans oil and there is no metal shavings

Bike revs good in all gears but forward. I know I can't bee the only person this has happened to. I have been racking my head for a week. Nothing makes sense if I push it while it is in gear and turned off I feel no added tension or stress from trans gears.

Can I ask how you resolved this issue? I had the same thing happen to me today. Machine worked fine, loaded on a trailer and drove 500 miles to our destination, now it wont go forward, only reverse. Any advice you can share would be appreciated. thanks

Hi im new to all this I hope I get some feedback . I'm having same problem on my Polaris 90 and cannot figure out what the problem is any help will be much appreciated

I took the gear box apart and found no issues. I threw the atv back on the trailer and pulled it 550 miles home where I took the belt cover off and again found no issues. I put it back together and miraculously it worked fine and has ever since. I have no clue what I did to resolve. Wish I could provide a better answer.

Ok well thanks for your feedback I'll keep playing with it.

Did anyone ever solve this? I have a 90 doing the same thing. Runs good in neutral, perfect in reverse but I have to push it to get it to start moving in forward. No restrictions, it pushes smoothly

I'd check to see if you picked something up in your clutch.when you remove the cover tap the clutch with a rubber Malloy while turning slowly.

This is an older topic, I would start a new topic on your issue in the polaris atv forum.

Did you remove the limiter wire

Check the front clutch rollers. They might have flat spots and its not allowing the belt to change tension. Feels like your starting in third gear. That's why it goes fast after you get going.  Sometimes its from the belt wear build up

I would pull the clutch and clean it throughly. I had the same issue and this seems to fix it.
