HONDA ENGINE CLONE! Hammerhead GO Kart GY6 150cc to 420cc Predator Engine - MUST SEE! Part 1

[@rey5872]

I just recently did a predator 420cc swap on a hammerhead 250ss chassis. I wouldn't start this build without a good welder and some fabricating knowledge

[@jerrylight6684]

how did this turn out? i have the older model and was considering the same idea. wheres part 2?

[@mikemoore466]

I installed a 420cc predator on a spiderbox and bypassed the governor and it is very fast. I cannot imagine a 670cc on one. I also have another spiderbox with a 212cc with mods and it does really good. It's about like a 150cc gy6. But that 420cc is a beast. The 212cc runs 40mph. The 420cc runs about 65mph.

@@mikemoore466 did u modify the 420cc?? Do u leave the governor on and did u use the stock axle?

[@mikemoore466]

knockout champ56 I bypassed the governor that’s a must. I haven’t modded it yet but I will. I used the stock axle and turned it around where the sprocket is on the left side. I welded a bracket for my brake caliper. I bought a 420 sprocket off of go powersports that has the right size hole for the hub. But the largest sprocket you can use is a 50 tooth. It is very fast.

Dose the 420s fit on these with no mods

[@ians1464]

Go with a 670 or you're going to be bored

I'll buy it for $1,000
