I need to order a new battery and tender for my Kaw Prairie 360.

Any recommendations on a battery? I want a maintenance free. The drain line on the last battery and corroded the hitch where it drains.

I was looking on amazon at a Yuasa, but dont know anything about them.

Also the valves need to be adjusted pretty bad I think. It wont idle without dying. I was going to pay a guy but would do it myself if someone could tell me how \:D

Thanks for any info!
