    Twin Engine Dual 18hp Duromax back from the dead

    Ok so the twin engine go kart is back on the grind stone and will be coming along in the coming months since I've got some jingle and free time. I got a little sidetracked with other toys like boats and mud trucks and what not. If you don't know what I'm talking about search this forum and...

    Sound system for go kart?

    I'm thinking about a small sound system. Initially I thought about a portable Bluetooth speaker mounted to the roll cage. I don't wanna have wires and a head unit and all that mess on a go kart. The kart is a crossfire 150.

    Brake setup suggestions?

    I have a kart that weighs 150lbs, I weigh 160lbs, the engines weigh 75lbs a piece. It's a twin engine 36hp build with mods. I'm thinking two mechanical disc brake kits? I thought of twin drums but idk if that would hold up. If you have any suggestions please leave me a link! Thanks guys!

    What size jets do I need?

    18hp 440cc Duromax. The stock main jet is 100. And I'm adding unrestricted header pipe, air filter pod connected directly to carb, governor removal. I'm guessing id go up two sizes but I'm not sure. Thanks. Also would a jet drill set be better to buy instead of new jets?
