So its good enough to just drive it around for a bit every few weeks then? Also what "seals" are you talking about and does gas always have ethanol?Its never good for a machine to just sit. Beyond seals and, sometimes, bearings drying out, if you have any ethanol
in your fuel you're asking for problems. If you know you're going to not use it for several months, I'd drain
the fuel and run it until it dies. Put the battery on a charger and, if you can, elevate the quad off its tires. If the storage
area is damp, I'd spray the steel parts with something like WD40. It would be much better to just start the quad
and run it around every couple weeks. Having said that, my quad sat in a snowy field for almost 10 years.
To get it going here's a list of things I had to do.
New start cluster
Overhaul the calipers and drums
Rebuild the master cylinder
Get new emergency brake cable
Change all fluids
Get new wheels and tires.
I was lucky that the wheel bearings and CV joints were good.
Now it runs good and everything works. Even the winch.
