Order the original part number bowls from Bombardier. 398544. The factory will supercede them to the current 2014 part number: 437214. Those are aluminum. Unfortunately, they are on national backorder at this time. When you get the new bowls, the mains will be swapped over from the plastic bowls. Unfortunatly, it's not so easy with the mid jets. The aluminum bowls use a different thread size mid-jet. You will have to purchase 6 new mid-jets for the new aluminum bowls. Get the same jet orfice size, with the new threads. Your dealer can help. These warped fuel bowls were a huge problem on these engines. Not a matter of if they would warp, but when. You should see marked improvement with the new bowls. If you don't want to wait for the factory bowls, this Bombardier dealer has 3 new pics in stock:
VANS SPORT CENTER INC, 1855 ALPINE AVE NW, GRAND RAPIDS, MI, 49504-2872 (616) 364-0666, INFO@vanssports.com. Part number: 0437214

awesome! thank you, i sanded the plastics down and noticed a huge difference, no more fuel waterfalling out of the 2 and 3. the warped bowls were a huge problem and alleviated the stutter and power loss

As much as you want to resolve fuel leaks from the bowl gasket area, there is a secondary issue of warped bowls: potential air leaks. Also possible to get air into the venture tube area, causing the engine to run lean. That problem is not so obvious and is more fatal to the long-term health of the engine.

anyway to check for that? im on standby until i get the new bowls - thanks

I'd just hold off on running the engine till you get the bowls swapped.
