Stage 7 carbs & filters these came off a running bike it idled perfect but cut out under hard acceleration probably jetted wrong it does have 175 jets which is pretty big. I just changed out the # 1 carb do to the air fuel screw being stripped & looked inside the other bowels & they were all really clean. All air fuel screws move freely now. . It will need new hoses on the stage 7 canister. It does not look like it has been long since someone was in them all the gaskets looked pretty new in the one I switched out. I would not expect to just put these on & go they will need tuned to your bike & possibly a light cleaning. $ 350 plus paypal fees & shipping .
