They make filters called engine savers. They work well in sand and grit conditions. I wouldn't jump that thing on the street unless you want to change the diff gears or shaft alot. OH, get a tackle box and start filling it with body clips, extra D cells for the glow plug igniter, glow plugs and wrench, rx and tx crystals if that thing uses those, after run oil. That kind of thing keeps you from carrying a big box and keeps things organized. Try not to hit yourself in the ankle with that thing at full speed. It'll do more damage than you think hahaha. GL kiddo!
