Hey guys i just purchased a 07 summit adrenaline 800r with 141 mi. it has 151 in track. After reading some of the posts on here about 07's i am beginning to rethink my purchase. Have not had it to the hills yet to really try it out but so far i am liking it. What are some of the things i need to check on being a 07. I read on here about there being a clutch update, is that something that ski doo will replace or will that be out of my pocket expense? Also where can i find the v.i.n. # on my 07, it is not stamped on the r. side of the tunnel like my 03 ? Any advice will be appreciated i am still getting familar to the snowmobile world. Thank You.
