    Default The F'n Juggernaut - Yamaha FJ2400 Build Video Documentary

    I'm putting together a video-documentary on YouTube on my next dual-engine motorcycle build: The F'n Juggernaut - based on the FJ1200 (see what I did there... F & J?!?)

    Click the pic below to launch the video:

    I've been posting in the Japanese Builds forum if you want to see what I've done in the past, but Like & Subscribe on the YouTube for notifications on what I'm doing now. Hopefully, the culmination of this build will be a run at a record at The Bonneville Motorcycle Speed Trials 2021!

    The FJ is an awesome bike, it was the 2nd bike I every owned, and the strongest bike I've ever ridden, even stronger than my 87 Vmax, me at 19 (look at them guns).

    I've always had one buddy or another that rode an FJ, but like most, I dismissed it as an "old man's tourer". I was actually shopping for a Katana 1100 (so I could stick with Suzuki & some of the stuff I already know) when the two FJ's literally plopped out of the sky. Once you look over the specs, the FJ1200 engine is phenomenal!

    • Over 100 rwhp
    • air-cooled, with oil cooler - no ugly radiator to have to hide
    • legit 145+mph top speed (may or may not be GPS verified by me)
    • suspension components to handle that speed
    • proven high mileage reliability
    • guy are giving them away

    Basically, any style that's already been applied to a CB750 chopper can work with a much bigger, more powerful, more fun-er-er FJ, and $500 CB's are getting harder and harder to find. Now, there's a bunch more wiring and an ECU to deal with, but you can easily hide all that stuff and cut out whatever you don't need, like every other chop project. She's a fun platform that I am having fun trying to figure out.

    This time around, we go International!
    I reach out all the way from Across The Pond to get by with a little help from my friend.

    I'm getting more comfortable riding the Juggernaut & having much fun in the process.

    Just a few of the zillion drawings I've done to figure out how I'm going to build the new frame.
