I picked this sled up after the season. The carbs are set up with all stock main's and she is way rich, i'm thinking dropping down to 400 or 380 main's. This sled will be used between 0-2000ft in up state pa. Any input who run these motor's would be very helpful.


Any 2004 switchback owner's out there, what do you think about this
sled (let's talk)

i think you can go 380 easy. i know guys running 660's with 340 jets on 10 degree days. the 380's or 360's range is probably about right
