Bought this sled new in 2022 it has: A silber turbo kit Boondocker airbox and charge pipes Bikeman clutching I’ve rode it a season with this set up it’s been turboed for 2 years. Runs better than factory turbo sleds and has little to no boost lag. Starts first pull every time. Always kept in the garage and cleaned and looked over after every ride. It can be turned up to 12lbs of boost it has the 7lbs boost spring in it now I also have the 5 and 3lbs boost springs. Not in a rush to sell $8,000 obo text with any questions.
