Replace Your Intake Seals

Question for Fix My Hog I have a custom bike and it has a 1995 Harley engine from a Sportster 883, the problem the bike is very hard to start and it coughs or back fire from the carburetor and sometimes from the exhaust. Do you think it’s the carburetor? I leave in Denver Colorado thin air and high altitude.

    You can use WD-40 and spray it on the 3 seals as the engine is running, if you have a leak you will hear the engine run up when the spray makes contact with the surface. Have you done any Carb jetting or idle fuel mixture adjustments? If it isn’t the gaskets I would check the idle fuel adjustment and possibly the jet sizes and adjust for your particular intake/exhaust combination.
