I finally got my first atv a couple months ago. Its a late 2004 sportsman 700efi. Ive been doing a lot of plowing lately and was having trouble going in 4x4. I've read through the forum and decided to change all fluids before tearing into the gearcases(good thing cause it looked like they were filled with chocalate milk). That seemed to help alot, but when i was working on it , noticed i'm running two different sized tires. 25-8-12 in front 26-12-12 in rear. Is that normal?or what am i ruining by running this?

25 on one end and 26 on the other isn't right. You might measure them, they could be very close to the same diameter. All tires don't measure to the same spec written on the tire.

Yes it goes in 4wd about 90% time now, thinking about changing it to flush out all junk from before, but pretty happy with way it works now.
