hey, just picked up an 08 70 shifter. have a couple of questions.
1. the tires that came on it are big mammoths and i was told that they came on it new. should i change for mx and go to a smaller tire?
2. where can i buy a quadtech seatcover?
3 i thought the front end ball joints were a crazy design, how have they worked for you guys, and if you changed them what did you go to?
4. i know to change the tranny oil, how often? which oil do you recommend?
5. any other maintainence that i need to keep a close eye on?
(doesnt include checking the tightness of bolts, i figured that one already)

thanks alot
bryan
