    I will add some of mine later. Just a quick thought.....banshee motors are my favorite. So easy and intuitive in the case dept. I wish Honda had done something similar.

    Still much to do. Gotta do something about those tired old wire sleeves for sure as well as that hideous Hi-Low selector.

    I was born and raised on Venus & I may be here a while.....

    Glad you asked. Most of that engine was in the World record Pro Mod bike of 1976. 9.44 @ 146mph set in Houston TX. First 1200cc Z1 ever built and the first hand made drag pipe EVER built. Terry and Byron copied and marketed it (I shiit you not). Would you believe this idiot sold it for $200 bucks? ( I shiit you not) they called it the ‘Dinko’ pipe.

    Len Heromachuck (don’t trust my spelling) built it and rode it back then. He was a Kawi dealer out of Kenora Ontario that did the mods on all the sponsored Kawi sled engines in the 70’s. Everything but the tank is one off fiberglass. Most of the frame I built as Len’s set up was as scary as hell. Lighter than mine, but the think never went straight for more than 10’ at a time. I made it longer sync wider and unfortunately heavier, but I was bracket racing, not trying to set world records.

    Len got into nitro bikes and sold it to Eddie Hart who matched the 9.44, but only got to 142mph.

    Eddie had type one diebetes and was going blind, so he sold me the bike in 91 or 92. I promptly blew it up and destroyed much of the engine. I took out a $10,000 loan (last time I ever went into debt in my life!) and rebuilt the whole bike from the frame up.

    I managed a 9.56 at 146mph one day and sold the bike to a kid I had introduced to drag bikes. Had to let it go when I moved to Mexico in 99. He’s totally redone it. It has a car tire now and has run 8’s.

    I love sharing the story, thanks for asking buddy :
