ok im sure theres lots of horror stories out there... but lets hear some GOOD ones ill start... so i buy a USED sled from my local KTM/Polaris dealer, have it for around 3 weeks and the engine blows....great. so i tell the dealer what happened, and im expecting them to give me a big bill. they rebuild my motor with BRAND NEW wiseco pistons, all for FREE. talk about a good dealer. thats why ill always go back to them.
