frequently asked questions

  • Are your engines covered by a warranty?

    Racing is exciting and unpredictable, and we understand that your FZ SHIFTER investment represents a significant commitment.


    Thus, we provide a 30-Day warranty from the date of purchase on any manufacturing defects only. Regardless, any warranty questions or claims are only accepted on engine kits that have been registered and are subject to the warranty process only.

  • How do I care for my engine to keep it in good condition?

    Do the basic, clean the exterior with simple engine cleaner or even a water-soluable mix.  Visually inspect your engine, keeping it clean makes this easy


    Make sure to always pre-mix your fuel and oil, and coolant is always in your radiator.  


    Give it time when first starting your engine to allow the water in your cooling system enough time to warm to operating temperature before going flatout!

  • How much oil do I mix with my fuel?

    Good question! First, we recommend only using a racing fuel that is 98 octane and above, preferably 110 and above.  The oil should be a high-quality synthetic racing oil such as XPS, ELF, or even Motul.


    The ratio of oil to fuel is 32:1 or 3%

  • What's the right jet setting for my carburetor?

    Don't worry,  once you unbox your FZ Shifter, there will be a sticker on your carburetor box with instructions.  It's simple, follow our lead and focus on driving and having fun!

  • Do you offer international shipping?

    Unfortunately we do not offer international shipping.  We can ship our FZ SHIFTER engine kits to anywhere in the United States!

  • What is your return policy?

    We do not accept returns unless authorized.  If authorized all returns will be subject to the terms in our return policy.
