When you're working on setting the rear chain, do a check on the swing arm mounts. It is common, thru lack of grease, for the bushing to stick to the bolts and start rotating them. This results in the bolt holes in the frame getting wallowed out making your chain adjustment near impossible. I had to weld on extra metal and put in remote grease lines to keep the problem from coming back.
I use mine every fall for hunting and all winter for plowing. Nice to be able to pull start a machine in the winter if you have too.....
