Try and find out if it's already been replaced, if it hasn't you'll have to decide if its a risk you want to take. It may never fail, then again it might? They run $1500-2000 to replace. I know of an 02' with 12,000kms that was never touched, but I can think of half a dozen more than never made it past 4-5000kms. I've only seen one built after they updated them in 05 fail. It was an 07? the bike was abused.
I'm no more a Can-am man, than a Honda man, or Yamaha man, or Arctic Cat man. I am loyal to no brand. If you looked in my barn you'd find more Honda's than anything though, I have only the one Can-am.
