Got a Skyhawk GT5 kit and a Yamaha YZ80 expansion chamber. Will be porting, windowing the piston, planeing the head and the top of the jug, replacing all of the studs, and making a custom tank. More pics soon.
 
Polished the combustion chamber and the top of the piston to prevent carbon build-up.

Been building it in my spare time. Got the head and the top of the cylinder milled flat. The YZ80 exhaust should be here today. Will probably be finishing it up this weekend. More pics soon.

What are you using to join the intake to the copper? I tried something very similar once and used solder but it melted that close to the engine. I got lucky that it didn't do any damage. If you have a friend with a map or acetylene torch braze it.

Also the copper is soft and will oval just enough to leak where the carb clamps on so cut a piece of pipe or something to put on the inside to stiffen it up a bit.
 
There are 2 elbows connecting the carb to a standard intake.The 2 elbows are soldered and the connection between the steel and copper is jbweld. If I have problems with it, Ill probably just make something else completely.
