Im in the market for a late model sled. Im interested in 19+ RMK, Alpha, Summit. I see guys selling "modded"/bolt on sleds with warranty. How does sled warranty work when say a sled has a cut tunnel, stage 2,3/turbo, runnning boards, etc..bolt on parts. Does a warranty still apply? Or do you need to return it to stock before anything is fixed by a dealer? The sleds i'm interested in are not "local" sleds, how has your experience been with buying used warrantied sleds and dealing with any issues. Thanks for time.
