It has been quite a while time wise since I had to do maintenance on my Wildcat X since I hardly ever drive it since I bought my sand rail. I have a trip to Coral Pink coming up, and the X is due for an oil change and valve adjustment as well as all the stuff I do every 250 miles or less such as the diffs and air filter. The designers obviously did not talk to each other when they stuffed a quad engine into this chassis as you have to take most of the rear plastic and heat shields off to get to the valve covers. The oil filter almost could not have been put into a worse location. Sure, you can get to it when doing the valve adjustment, but you WILL be dumping dirty azz oil all over the skidplates and garage floor. Even the front diff takes several extensions and u-joints to get to the drain plug.
