Was originally planning to have my son's 2012 yz125 ported and head modded by KB5 in PA. Running into $$$ issues during the upcoming offseason and might not have enough to do the porting. So here is the big question. Does a head mod provide enough of a USABLE difference to make it worth doing by itself. Bike is stock with the exception of the FMF Fatty/Shorty. Want to keep using Sunoco 93 pump gas. Suspension has already been fine tuned, does not like any aftermarket reed systems and he rides it like a boss. Races mx in the mid-atlantic states and is upper B class rider.

Can do. Depends on what the head mods are. If your squish was out of spec just correcting that can make a big difference.
