I'm looking for a sled that had case reed induction yet had 44 mm or somewhere near that size carb. I know Ski-Doo's always ran some big carbs on their twins, But many of their mid 90's sleds are Rotary valve. The reason I'm looking for this particular setup is to gather a list of parts for my project with my spare 650 motor. In particular I'm looking for carb boot and reed stuffer, and plan to have the cages that I will have welded to the cylinders machined up based on the specs of the reeds off the same machine hopefully. Any input would be appreciated.
