750cc Cross Karts Gets Mufflers & Destroys Tires!

We'd been having running problems with this 750cc motorcycle engine from a 1982 DOHC Honda CB750. We chalked it all up to carburetor issues, but comments from our viewers insisted that we needed back pressure on the exhaust in order for this motorcycle powered go kart to run better. Turns out, they were right! This custom UTV runs WAY better thanks to the mods we made in this video, including mufflers from a Harley Davidson motorcycle, new spark plugs, plug wires, and ignition coils. Can't wait to open this thing up again!

I like the way Ike thinks, who needs mufflers? Lol. I agree, merely a recommendation not a requirement lol. Im sure your neighbors appreciate the cross cart purring like a kitten. It would be cool to make an open valve piece to the exhaust that can be opened or closed when you really want to hear all 10 thousand rpms in a less populated area. Also if the fuel tank does get too warm near the exhaust you could always make risers on the base and attach it to the chassis to get it above the mufflers. I don't think it will be necessary but something you should definitely check periodically during longer periods of testing ;) Awesome build, probably my favorite so far.
