I just bought a used t200 from a dealer. But when I got it home and started using is some something seemed a little wrong. the right track isn't wearing on the inside like the left. Turns out the drive gear isn't properly aligned. It is completely offset from the rear idler to the outside. Looks like it has been this way for awhile, as the inside of the idlers and the outboard bogies are worn on the side. How do I realign the drivegear? it needs to move inboard about 1 inch. What caused this? I do not have a MX manual yet so I don't want to just tear into something blindly.
