Finally got to rid today in the Oquossoc area and I am pretty impressed with with this little guy. There won't be another 500 that will even come close. I rode with 2 guys, one had a 600xc and the other had a 500 xc. Never saw the 500 xc all day. The 600 xc would pull me by a little. The mid range on this sled is silly. I think (?) the idle speed jets need to be adjusted one notch to elimenate a low end bog so iv'e been told????? Maybe a little tinkering here and there and I'll be able to pull the 600 xc. Any suggestions.
