We race the Rat Karts! Was the upgrades worth it?...

We did a few upgrades on Damon's go kart so we wanted to put it up against my stock predator 212. It rips! Next we are advancing the timing 8 degrees and we'll see the gains from that.

@1:42 I saw the can and I first thought, "whatever that is, (welding) spatter is going to make that taste nasty!"
Then I saw it is a Miller Light...it's not getting worse, just different.

Why bother with an air filter?
Just bolt on a velocity stack, the engine is disposable. During a HF special, the air filter kit will cost more than a replacement engine. Just get a couple.
20 years ago I built a kart with a real Honda 6.5, and even when the engines weren't cheap, the racing crowd was running only velocity stacks. So, the bell-mouth intake spacers were cheap & that's what I did.
(1" thick alluminum donut to replace stock intake, works with stock carb studs after removing the plastic air filter housing)

With the governors still in, it should still have the same top end speed.

Bonding primer and white spray paint. They won't last forever but easy touch up.
