chinese 2 stroke

I have finally busted out the bits for doing port work. Never done this before but looking to get at least 30mph out of a Micargi fat tire im building. I did my best to port match the intake and also make the exhaust a bit bigger. Not much just a bit. So does this look correct? Thanks for any...
