    Default Shovelhead 93” stroker with s&s super g carburetor

    93” stroker Shovelhead also there’s dual spark plugs(4 spark plugs). When my dad had bike it was running perfect since I inherited the bike I was thinking getting the bike Dynojet tune by the Harley dealership. Does anybody have any experience with Dynojet tune. Also, is it expensive for Dynojet tune?

    A few comments in this 2017 thread that may be worth considering:

    What makes you think it's running badly?

    ^^^ Fully agree. A Super E should suit it better.

    Go by the suggested jet sizes and go from there. Jetting it by running the bike will get you close enough, unless you are planning on racing the bike.
    Just make sure the timing is right, retarded with the dual plugs in mind, and make sure you don't have any intake leaks and all that.

    Do not, I repeat, do not let a dealership Dyno a Shovelhead!
    Dynojet is a brand not a technique or service
    Find yourself a shop that knows the older bikes.

    As asked above, why do you want to Dyno the bike?

    If you are going to ride a Shovel you need to do some serious study and become thoroughly familiar with its systems.

    They are not modern motorcycles in the sense that they are not "appliances". They require owner involvement and lots of it to serve you well.

    Disregard anyone who is not an experienced Shovel mechanic. (BTW Dragstews is a highly experienced wrench whose posts help many 33ers.) Dealers stopped supporting Shovels decades ago. Find a good independent mechanic for only as long as you need to learn how to be your own mechanic. if you aren't up for the challenge you probably need a different motorcycle. Much love for Shovels on my part (I have two) but I don't sugar coat anything.

    Shovels are fun! Have fun.

    You came to the right place to learn. Get a factory service manual and factory parts catalog, whose exploded view complement the manual and whose part numbers will help ordering online. Study widely online and learn the correct terms for parts, basic four stroke engine theory, and get comfortable with Shovel electrical systems which are pleasantly simple.

    Change it out to an "E" and see how much better it runs..
    Dragstews is wise. A G on an engine that size and intended for street use is giving away performance, not improving it.
    S&S has tuning instructions and videos.

    Farmall says it well!
    I have three Shovelheads, one is for sure a troublehead, lol.
    But they all have their "moments" of need the attention!
