i have been reading about some problems but am wondering what i should look for while inspecting sled ( besides the obvious things ) . it has come from the states to canada so all the scheduled updates would have to have been done already . i know it has the secondary water cooler installed . i am coming off of an 04 rev and do not know much about the xr chassis . the machine has 6000 miles on it and is a 121" tnt for 7300.00 canadian . seems like an ok deal ..... please let me know any info it would help a ton in making my purchase . thanks guys .
