Is this okay porting job?

Stock was dyno'd at 1.8HP.
Check out the channel on youtube "2 stroke stuffing" There you can learn alot.
Im looking at this photo again and I keep wondering should I make exhaust ramp on piston? It looks to me like piston should be lower... As you can see exactly top of first ring is bottom of exhaust port..

Do not do exhaust ramps or transfer ramps.
They will mess with your timing and destroy any hopes of a proper squish band which is critical.
The piston sticking up is normal for these engine's.
Okay.
Today I was decking my cylinder and found some copper 2mm wire and thought it would be good for measuring squash gap but it is too stiff. Which wire should I use or some other technique?
 
Use thin solder.
Measurement should be with .5mm-1.5mm with .76mm being the best.

Picture of your cylinder head would be ideal. (combustion chamber portion)

98% of the time you will need to sand in a squish band using your piston as a sanding block.
I bought cnc head from ebay, but it didnt arrievd yet so I'm using stock head for measuring. Is squish band going to be the same or?

Nope. Both will be different.

Good cylinder head choice though! You will get alot more cooling.
Well I'll keep sanding the cylinder for now atleast .5mm because it still has a lot space and then when head come I will fine tune it. I found some straight pipe so I will weld it tomorrow to make my exhaust longer.
 
Show a picture after you wash it and assemble it with piston at TDC and preferably measure it with calipers.
This part is critical and we must go slow. We want to have a little extra room rather then the piston not having enough room and getting stuck at TDC.

Everything is going to compress when you torque down the cylinder when your done and then their's also thermal expansion when its running. This should be noted and accounted for when altering your motor.
I hope photos are good!

They are great. Looks about 2mm. You can safely take 1mm off.
This will further tune the timings but I tryed to give you room to land in the right amount.

After should post more pic's.
Hi man!
Today I have finally started my engine and with bit of jet changing is working better than ever. Now I had put 65 jet but it is four stroking on wot a bit so maybe I'll try 60. Squish gap i around 0.8 0.9mm. Thanks for all advices you helped me so much!! One more question.. Should I grease gears and with wich grease and maybe if you have some other tips on engine running better, if you dont have it doesnt matter you helped me more than enough!
