ported head

[sadinkins]

whats the best valve set-up for mx.i know everyone is running bigger valves but how much bigger?anyone have a good ported big valve head for sale?

[honda300EXtreme]

for mx i would go with +2mm valves
and a full race port,

if you talk to colby at C&D he can only do +1mm valves

God, it's been a long time.. but I beleive mine was done w/ +2mm exhaust valves and +1mm intake valves by Mickey Dunlap.

For the most part I let him decide what was the best combination.
