porting

[rylibritton19]

i have a bt100 and plan on porting it,i am only knew to 2stroke tuning so could someone point me in the right direction for how much wider to make my exhaust and intake port and how much to raise and or lower both ports. i was thinking after a little research 1mm of each side and 1mm off the roof of the exhaust and 1mm of bottom of intake,i could be completely wrong though thats why i am asking also i plan on using a g2reed, window piston,a ktm50 expansion chamber and just a stock nt carb

I'm new to port timing , I did my zeda 80 firestorm going by this. I used a printable degree wheel on the magnet.
