Am Ex High Speed Run

[Kentucky Boy]

Got the old Am Ex out today and made a good run. It had more but it was pretty fast.

That kart is gorgeous! I’m restoring a 405. I wish mine was a live axle like yours hehe.. I sprayed mine last weekend with rustoleum safety red thinned down with acetone through a $12 harbor freight sprayer. I think it’s a pretty close match to the original color. Hope mine turns out half as cool as yours

What mods do you have to the engine? I see a Mikuni carb but what else?

 

[zbillz]

Yes, also curious about your gearing?
Great looking kart !

How is it on low end? I'm assuming you would need pretty tall gearing for that top speed, but with that much work done to the engine plus a Comet 30, I imagine it accelerates pretty well too. That thing needs a Juggernaut driver!
