Last night I finished mocking up my gt2a_s build, and it started right up. Ran like crap, but it ran. The air filter fell off and then it came to life... Go figure? Anyway I used:
66cc china girl from Motovelo (had great luck with the first one)
6:1 compression billet aluminum head (unnamed source refuse to give credit)
ported jug (unnamed source refuse to give credit)
cut piston (engine came from Motovelo this way)
drilled wrist pin (engine came from Motovelo this way)
rod and wrist pin bearings (came with engine installed them myself)
Mikuni vm18 carb (unnamed source refuse to give credit)
stupid CNS 90 degree air filter (crap don't waist your money)
banana expansion chamber (sound awesome!)
billet aluminum sprocket adaptor (unnamed source refuse to give credit)
billet aluminum 44t Sprocket (unnamed source refuse to give credit)
KNC 415 chain (unnamed source refuse to give credit)
Motion Pro throttle (unnamed source refuse to give credit)

For the bicycle components I used:
Worksman 26 x 2.125 HD double wall 36h alloy rims with 11g stainless steel spokes
Maxxis Hookworm tires (very sticky in a very good way)
Maxxis presta valve tubes (work well, but kind of a pain in the ear)
Rock Shox 29" XC28 Mag TK 100 coil fork
some cool looking 0-60 degree stem from a local bike shop
Sunlite MTB City aluminum handlebars
Shimano Deore disc brake hub (drilled spoke holes for 11g spokes, plenty of metal left)
Origin8 disc brake (less stopping power than I anticipated)
Black Ops bottom bracket set, crank, and BMX chain ring
M-Wave double leg center stand (crap don't waist your money)
Schwinn alloy peddles
210 chain from the engine kit
Schwinn coil spring seat
XLC coil spring seat post (crap don't waist your money)
Cheep squishy grips from K-MART

After the air filter fell off it stopped gurgling and bogging. I fiddled with the carb a little this evening and it almost idles. So fare it seems to run strong. I'll find another air filter and tune & tweak it out this week. Enjoy the pics...

Thank you Intrepid Wheelwoman. I road through a small puddle and I'm thinking of adding a pair of 90 degree hugger fenders...

Fenders (mudguards) might be a hassle to fit and maintain so they stay in place and don't cause accidents, but I've always fitted them on my bikes. I live in a country district where the major activity is dairy farming so riding without mudguards on some backroads is only for the truly brave.

I live in the Mojave Desert and we don't get much rain (average rainfall is about 8 inches annually. So mud flaps are out of the question, but shorty hugger fenders would look cool...

And ride it I do. Only have a couple of miles on it so fare. The more I ride the better it runs. Fixed a gas leak today. Cheap ass fuel valves. AS with the first bike (blue gt2a) the head bolts, carb clamp, and motor mounts needed tightening. Always check fasteners...
