I just completed a complete engine rebuild on my xcr and am in the process of installing the engine back into the sled when i noticed i dont have anything hooked up to what polaris calls the breather pipe on the crankcase at the base of cylinders 1 and 2. can anyone help me as to if anything is supposed to be connected to the breather or if it is left open the the dealer is telling me.
no you are thinking of the pulse tube to the fuel rail. this is on the back of the crankcase at the top just below the base of the cylinder. it is probably about an 1/8in in diameter. the polaris dealer in traverse city is telling me they think it is just left open but i find that hard to believe on a 2-stroke motor
