All my comments are not criticism.

Is the exhaust opened up to the diameter of the exhaust gasket?
The exhaust could be polished shinier.
At the bottom of transfers I make that bump on divider a longer taper.
At the cylinder I make the taper smoother and a longer taper. Almost making a knife edge at bottom of steel liner.
The intake needs no work behind reeds.
The boost port I make a longer taper towards bottom. And a little more on sides. Make sure there are no boogers at port opening to cylinder.

It's been a while it is opened up to exhaust gasket and it took me a while to answer because I blew her up and after 2 1/2 months of saving money I did a Vito 3 mil with they're clutch gaskets and seals and a wiseco piston I did the stock bore that I ported the one for this thread and two days ago I rebuilt the full engine by myself top and bottom and I put that cylinder on and ran and it would run a little sluggish a 1/4 throttle but after shee ran awsome and powerful I'd like to thank you for helping me along the way of the cylinder I did keep the fmf fattt
 
Did you try air screw about 1/4 turn each way, if no improvement return to original position. When carb was cleaned could see through pilot jet? Did you remove emusion tube/main jet holder? There are several tiny holes on side of it.

Yes all the tunnels or holes are free from gunk and it is a Chinese makuni it might be why too because it's acts like a keihen carb

See that changes things. You'll have to do some digging, but you need to find out the stock needle and slide cutaway and compare it to what your carb has.

You could try raising the needle one clip, if not better lower one notch from starting point. Also try tweaking the air screw at the different needle settings, returning to start point if no inprovement.
