I got the bike from VVC college, in which I'm attending, in Victorville CA.
It was donated to the automotive department and had sat there for five or more years.
It barely ran. They had used ATF for two stroke oil. It had a big vacuum leak but the carb was leaking fuel so it kinda canceled each other out until it would heat up.
So I gave the dean the $150 he asked for it. He gave me back $50 about half an hour later saying it's not worth $150. The DMV was a nightmare and had me going back and forth from there to the school. I think on the forth trip they felt bad for me and let me register it without the original owner's signature. I thought it was going to be registered as a motorcycle like all scooters are so I took the M1 test. It wasn't. They told me since that it was originally registered as a moped that they couldn't do anything more than to register it as such. I should of taken the M2 license test, fuck. So I got it running and have been riding it ever since.

Now it goes quite a bit faster than the stock 25mph but doesn't get 110mpg anymore either. Sacrifices sacrifices :)

Here's the mods so far.
YT60 jug and piston. Beat to hell now.
Champ head.
Ported the cylinder and opened up the exhaust flange opening plus tons of other top secret shit.
Port matched the exhaust header to the cylinder.
Puch Proma GP dimensional exhaust copy.
PW rear gears.
MJ50 2 speed case. Has the left side crank half and case from a qt.Has some internal case work done too.
New All Balls brand main and crank bearings.
New OEM rod.
New OEM big end pin.
New OEM wrist pin.
New OEM roller wrist pin bearing.
Boyesen reeds.
Enlarged the reed block with chanfered bridge. Port matched the intake to it(opened it up a lot).
VM 18 Mikuni carb press fitted then JankB welded to modded intake which has been bored out because that tiny intake is pitiful. building a intake manifold from scratch is on the to do list.
worked over the inside of the case for better flow.
UNI filter from a CRF 50
Polished right side case cover.
Oil pump delete.(going back on sometime soon)
Throttle control mod so the VM would open all the way.
H4 12volt headlight mod with 12volt lights all the way around.
Battery delete. Regulator delete.
GPS synced bicycle speedometer sensing from the rear wheel.
3 axis hp meter. All but worthless. I have to do a 1/4 mile pass to read the results.
PW right side swing arm and second shock mount tapped.
Lengthened rear shocks for pipe to ground clearance. Running three shocks but only one spring. Super sticky.
Foot peg relocation.
Swapped brake controls to left lever front brake, right lever rear brake.
Duct taped seat or skateboard deck. Whatever I'm in the mood for.
80cc dirt bike forks and axle.

So here is kind of an old picture I took in summer of  09. That's the pipe I built for it last time. 120 relief cuts to get those curves. WHAT A FUCKING NIGHTMARE! Something must of been amiss in my calcs because it was just way too long though it did rip on the low end. Here's a picture of me racing at Grange. I'm trying to build it up so next year I can take the non-variated open... dreams....

This is a short video of my gang, The Two Wheeled Turtles. It's my cellphone taped to my Qt's handlebars.

April 30th 2010:
So I'm building a new pipe and I want this to be the last one for a while. I want it to flow something fierce but the damn bike sits too low to the ground. So I built some shock extensions.
