Going to use this rear end from a kids quad. I brought it off trademe, someone scavenged all the good bits for a project of their own... but all I wanted was the axle.

These old school gokart rims bolt straight on too, awesomeness!

Then I ran out of mig gas. This wasn't really a surprise...i knew the bottle was close to empty, but been a tight arse I decided to run it completely empty. Just sucks that its a weekend.

Anyway, all fabrication is done, just gotta stick it together with the "metal hot glue gun"

I'm glad someone else is banging oversized engines on abandoned kids bikes etc to make them fun again. Worked for my kids with my scooter I built. If you need some 25h chain and sprockets I've got some new stuff here I never used.

Thanks Muncie - I'm using #35 chain/sprocket on this one as I had some already, but your offer was much appreciated.

 

Exhaust:

The factory exhaust just had a round hole, cheap to manufacturer I guess...but we can do better than that!

So I scribed the exhaust port shape onto the flange and tickled it into submission.

Finished up by draw-filing to make sure it mates up flat (it was miles out, most likely warped from factory welding).

I then cut the expansion chamber up like I did in the gokart build, with the plan to wrap it around the immovable parts but still make a nice flow...okay; its all about looks, but hey.
