i just bought my first sled (because i felt bad beatin on my dads lol) but its an '03 mxz adrenaline 600HO and i got it at an auction and i read that you're supposed to clean the RAVE exhaust every 1000 miles. I put 400 miles on it this year and i have no clue when the last time they were cleaned was. so i figured i'd clean them. do you guys know a link that would show/explain how to do this or do you guys know? any help would be appreciated. also, do you guys think i made a wise choice to get this sled? don't know much about it. but i like it. thanks
