We (my son and I) started with a old Spree, stripped it down and cut the frame tube at the rear mount.
We had previously decided on about a 55 inch wheelbase with a Zuma 2 stroke motor.
So it needed a longer lower tube. I got he closest american size tubing and machined up a inner tube to adapt the two differnt size tubes. We slide it in and drilled a couple holes and rosset welded the piece in and then finall welded the tubes together. Kid really getsa mad when the frame breaks in half on the track so I felt this was the best way to join the tubes 8)

Next we needed to build the rear frame section so we welded on a cross bar, drilled some 1 inch holes and bent up the two lower motor mount tubes out of 1 inch .065 DOM tubing.
We went all the way through the tube so I could weld both ends for better strength for the stressed tubes

Cant see in the pics but we snap a chalk line on the table to keep everything in line and use a few plumbobs. I also use a cheap laser level to make sure the rear wheel is parallel to the front wheel.
I machined up a couple of soild spacers to replace the motor mount bearings the stock Zuma uses and we made up a pair of simple mounts and once every thing was squared up and level I welded it up.
You get an idea of how long it really is... theory was to move the motor back but keep the rider in the stock position to keep weight on the front and reduce the tendency to wheelie... so far it has worked as intended!

Since we decided to run a Honda Elite body we started to bend up the tubing to support the body, seat and rear strut.

Nicks pretty good with the bender

Time to mock it up for a idea of how it will look.

Tok a piece of .125 wall aluminum tubing I had laying around and machined up some end plugs, drilled an tapped for 5/16 heim ends for the rear strut.

Notice the crazy carb angle.. yes it works fine like that!!

Rock Stars is what they are. I love the whole project.
I can believe the carb runs at that angle... Insane!
