PW 50 compression and milling the head

[94guy]

i want to raise the compression on my pw 50. i'm about put the .080 piston in it and would like to mill the head while it's apart. is there a rule of thumb on how much can be taken off? also i'm looking for a fmf pipe for it if someone has one laying around you want to sell let me know. thanks

I don't know the specs off the top of my head but if you call ken at PVK Pamona Valley KTM he is the man for porting and headwork on the pw50. the .080 over makes a good difference. You can also offset bore it for the YT60 piston and it will fly.
You can get teh fmf off e..bay for something like $180ish
