Blaster Big Bore service rather than new

wow those aerial kits are $1000 and i still got to send the top in. Im gonna give this guy a shot and review after. Im thinking this aint a bad price with the porting also included.

Why buy the ported top end, when the standard is 574, and KOR will port it for $170 and do the head for $60. That's almost $200 savings over buying the pre ported kit.

i would tack on another 150 or so for a new piston too. vito's sends cast pistons
