gt2-a 7g 4- stroke build

First off, I want to thank migueralliart, and kcvale for helping me with this build.

Well after two months I finally have my build 95 percent complete. Took for a few miles around town and it feels like a small motorcycle, the shift kit is awesome. I, also did a few bolt-ons to the huaseng motor for more power.

one think, I realize about this build and to anyone who wants to build a 4 stroke bike with a skyhawk frame, is not to use the gt2a-s frame, even though its designed for 4-stroke. Use the gt2-a frame which is meant for a 2 stroke build and cut off the front mount. There is not much room in the gt2a-s frame for a 4-stroke.

gt2-a frame:
power coated gray
cut off the welded 2-stroke motor mount

shift kit:
pedal cranks, motor mounts, sprockets, all power coated black

engine mods:
ngk plug
stainless steel flex pipe with tip, overall lenght 28.5 inches.
uni filter and adapter
drilled out main jet with #71 drill bit

That's a great looking package! I was wondering about the carburetor. I have a Phantom-Bikes Ghost 26 and have been upgrading it since the beginning of December 2014. I just added the AD Racing carburetor filter and have another carburetor about to arrive that will let me adjust the fuel flow. Did you have to adjust your fuel flow with your new filter? I have attached a copy of my new carburetor and a link to a YouTube page with a few videos I have posted of my two bikes. Keep up the good work!

There is no adjustment screw on the huaseng carb, so all I did is drill out the main jet with a # 71 bit, as the tutorial on affordablegokarts web site suggested.
 
On that brass fuel mixture screw does it control the fuel mixture throough out the power band?
 
Just a tip for HS 142's, try an NGK 7544 (CR7HIX) Iridium plug before you start jetting.
It's a tad longer than a stock plug for bit more compression and much better spark.

Also note there is guy making offset intake pipes to use an NT carb on them.
They work but not any better than the HS's carb but a good last resort if you can't find the right carb.
