What is this "maintenance" of which you speak?
I usually just run it until something
needs to be done. I'll give it a decent glance every once in a while to make sure nothing is rusty, bearings are good, shocks are smooth, etc. If I run in wet conditions, I might dab a little WD40 on some places. It seems diff oil gets dirty after 0.0005 seconds of running, so I replace the oil maybe once a season. Same thing with shock oil. Yeah, those parts would last longer if maintained better, but I usually break something before it gets to that point.
