Alright enablers of bad ideas.

What could you do with this pile I just drug home?

Power Barstool on steroids?

See if I  can shoehorn an inline 4 bike engine?

Harbor Freight Predator engine?

I figured for the purchase price, I can't lose money.

Do an electric ATV. 

Or...

It's a gravity racer right now. Take that thing to a big hill!

Turn the chassis into a full suspension go kart with hayabusa power. 

In reply to Grtechguy :

Are you in the Bring a Welder group on FB? There's all kinds of really bad examples posted there. 

Hellcat crate motor?

There's a couple of motorcycle engines for sale here.

LS swap it.

Take a powerhead off a 75-hp outboard and stick it in there.  Rig up some little radiator and terrorize the neighborhood.

Or, replace the tank with batteries and throw a Prius or Leaf motor in it.

So, you know cycle karts?  Go that route, widen, lengthen, motor in the back.  Roll bar and get hill jumpin.

oohh.. I like the cyclekart idea

I don't even think it needs to be widened.    it's already 4' across.

Check out Grind Hard Plumbing Co on YouTube for inspiration. 

I've seen plenty of 6-1000cc banshees...

A guy I hung out with stuffed his CR500 2-stroke in one. That was pretty hilarious to watch.

That would be the ideal powerplant.    Right on the edge of too much hp.

I would use it for the best yard kart ever to haul wood out of the forest with another quad.  A hay wagon with suspension, that way some of the logs make it back.
