My dealer is really good but, I'm questioning one of their techs now. I asked them about putting on a muffler and a clutch kit to weak up the lower end a little bit and their (head tech) says it will void my warranty if I modify anything on the machine. Now I work in a ford dealer and have went rounds with customers on this very subject. What we explain is if the failed part can be linked to the aftermarket part then ford will deny the claim but there is no such thing as a company voiding a warranty all together is there? Just wondering how some of the other dealers are treating you guys with mild mods to your bike. Mine is a 2013 850xp which only has 300 miles on it but needs a lot more bottom and mid range to make me smile.
