That's smart! Welcome to the forum. I'm completely clueless on this one, never seen one like it.
that's exactly what it is. I think Polaris makes them now. I would never buy a new one. I almost bought a complete used one that had wiring issues yesterday. I just couldn't get a trailer lined up. they appear to be about the biggest karts. I'm 6'4" and have trouble getting in this stuff. if you have other ideas of bigger kart models I would love to hear them!!!That thing is pretty rough, but it sounds like you know what you're doing. When you go do get a 2nd kart ( and believe me, you will ) if the Hammer Head is what I think it is ( modern Chinese kart, electric start, GY-6 style engine, reverse gear, lights, ect. ect.) Do yourself a favor and don't. They are a rolling electrical nightmare. Stay with older used karts that use an industrial style engine like the Honda you have. A LOT more reliable, and a lot easier to work on when need be.
I have 4 older 2 seater karts and they are pretty trouble free for the beating my Grandkids give them. Also welcome to the forum. You picked a great project to develop father and son bonding.
Are you talking about the "suppository of knowledge" again?It should be fun.
I can't justify the money they want for the new ones. I want to take it out in the mud and beat the snot out of it. if I buy something I want the one that people are selling cheap cause they can't fix it. I would just re-wire it. I fuel injected an old V8 bronco I built using GM throttle body fuel injection I got at the junk yard. pulled the junk yard harness out and kept what I needed. Ran like a champ on 4.3 liter injectors.At 6' 4" you're probably going to have to stretch most any kart you find. But you're probably up to it. Pretty easy to limit throttle travel whether at the carburetor or at the gas pedal while your young one gets acclimated to it. But you might be surprised at how quickly they learn. If you do decide to buy one of those electronic messes, I would take Denny's advice and buy brand new. Then keep it in the garage and never wash it with water or let it get wet. I'll admit that I am pretty biased against these things, but by far the most common problem on this forum is people having electrical problems with this style of kart. In my opinion, they just try to put too many gadgets in them, and the wiring system or harness isn't up to the job.
don't want to know.what is the suppository of knowledge
