porting and head mod???
« on: November 06, 2013, 11:26:23 PM »
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.

If you don't fall off you are not going hard enough
