420cc Off-Road Go Kart Built and Designed From Scratch

The steering problem seems to have been caused by the front tires being out of alignment. So I straightened them up and now it turns way better. They were far too toe-in.

Progress on a bunch of stuff.

I've been working on things every week, just wanted to show off the exhaust and muffler I made.

Can't embed this one:

420cc Exhaust and Muffler Sound Test

Custom muffler and exhaust I welded together for a 420cc Predator engine, all stock except for a high flow filter and bigger main jet.

It needs testing and painting but it's nearly done. And some other things, like making the sheet metal look nicer. As much as I can, at least.

You know the drill around here.

Post a video man, let see it run.

You forgot to say “atomic batteries to power, turbines to speed” before you started it.

Really like the fan idea for the CVT. They used to have those for both centrifugal clutch assemblies (usually a jackshaft setup) with a cover as well as for TC/CVTs. You'd see them on older parts diagrams, Comet Industries brand usually, and wonder what the heck is that fan for.

Engine sounds really healthy and I admire the central exhaust.
