5.5 HP, I'm told. So I take it replacing it is an important step? Not sure on the exact measurements, in size.
Edit - Quick clarification that I probably could have made earlier; I'm well aware that what we're doing is hazardous, and to your note of younger readers, NONE of you should try this yourselves. It's very dangerous, and believe it or not, I'm trained. And my friends... Well, I'm watching and training them.
Stuff like this is every bit as dangerous as it looks, don't let us pulling it off make it seem like a good idea.
That said, that's about why I've sought out this community. I know about stunts, and my buddy Kenny USED to know enough about go karts to have built this one with his dad, literally almost two decades ago... And right now, that's the extent of our knowledge.
Planning is safety, and while I've got the physics down, I know nothing about the little buggy I'm clinging to, aside from it's respectable ability to hold me.
I'm here to ask the experts to school me.
