I picked up a 1997 Yamaha Big Bear 350 2X4 a week or so back in non running condition, apparently they said it needed a new carburetor or a battery, I cleaned the carburetor thoroughly and got it running on idle and without choke now and it shifts into all the gears even into reverse. Aside from making me bounce a little when trying to start out with a bit of throttle the shock suffice to say needs work. Anyways I made a video of it running and would like your opinions on it, as to how it sounds while running. It seems like it has a little whine I'm not sure why that is maybe someone can tell me what it is. Anyways here is the video.

I've been reading threads here for a while now and figured it was about time I signed up and gave back a bit. My kids are gone from home now so I sold their Honda's off last fall I still have a few Polaris machines on the place to get around on. I use my quads for chore horses around the ranch so they get used but not abused if I can help it...which of course I can't...all the time... Well, thanks for havin me folks, Ima hava look around

Sounds great but yes def a whinny noise. Im thinking clutch, check all fluids and take it for a good run. Nice work, you can pick up a new seat cover for 30 bucks or make your own for maybe 10 bucks.

Bid was $3750. $4548 with all the fees. Hoping to see low mileage when I get the power going. According to the title, it was originally titled 8/2018. There is about $800 worth of accessories on it too. Came with no key so I got a $10 chinese replacement just to get working on it. Auction link: www.copart.com/lot/49761799 I wanna pull the clutch cover off too and see how bad it is in there. I'm assuming its a belt drive. I charged the battery and its been holding at 12.2v for 2 days(not connected) so Ill see how that goes later. Would like to get a sealed AGM battery if they're available. A buddy of mine said to drain everything from the engine, pour a little oil in the spark plug hole and manually turn the crank to lube the cylinder or the walls may get scratched up and lead to major blow-by. I heard it is ok to use 5W-40 oil in it so I will run a few oil changes through it with that before switching to the pricy polaris PS-4 oil. My buddy recommended like a half dozen oil changes to get everything out. Unfortunately its at my brother's house about an hour away cause I don't have room for it here. But it is in a heated garage which helps alot being in the Poconos in December.

Excellent advice by @Ajmboy ! I would pull all the plugs apart, fuses out and spray all electric plugs and the fuse box with dialectral grease. Label everything so you don't get confused as well as a few pics incase.

I'm using a quadboss atv cover currently and its pretty good. But if it tears or get another one, I've been looking at this one on Amazon for $27 and has pretty good reviews.
