1997 explorer 400 smoking bad

I just purchased a 1997 Polaris explorer 400 4x4 2 stroke. It seems to be smoking really bad. Like enough that you want to keep it moving as not to choke on the fumes. Is this just a dirty fuels system or carb problem? Or could it be a piston and rings?

2010 polaris sportsman xp 550 drive clutch replacement one way bearing

Does anyone know of an alternative to the $150 one way bearing for the 2010 sportsman 550 drive clutch? 1322809
Or will the 2011 and up bearing fit? 1521667 1521172
Or will the 2011 primary clutch work properly on the 2010-2009? 1322953
I see the price on the 2011 and up primary one way bearing is only around $40
Please help need to get this thing going.
Ideally I think I would put on a 2011 and up primary and then all maintenance costs would be lower in the future. If it will work properly.

Old New Guy

Hello everyone, I have been wanting an atv since they first came out. All that time I could not choose an atv before my families needs and so I went without. I am a hunter and enjoy the long days in the field but as I am getting older it is getting harder to do what I could when I was younger. Recently a family member sold me their 1997 Polaris Sportsman 500, it does need some work, but I now have a quad to assist me with hunting and hopefully snow removal once I get it setup with a plow. I hope to learn much about this machine so that I can restore it to a solid driving machine and will need your help and advice along the way. Thank you all for allowing me to become a member of this forum and I look forward to all their is to learn about this machine.

Just want to take a moment to say hi everyone. Just came into a 1999 Polaris Magnum 500 with low hours. Needs some work and this looks like a good place to get the help I need. Looking for a 6 phase speedometer-the outer ring on mine must have had something dropped on it and is badly dented. Thanks again for letting me join the group.
