MAC 21 & header
I have a MAC .21 I bought this year. It has probably has no more than 1 gallon of fuel through it at the very most. The piston and sleeve have been skirted and the drum has been plugged. Plugging the rotor really increased the RPM. I also machined a new spray bar/back plate that allows the fuel line to attach at 90 degrees. The stock fuel nipple length caused the fuel line to be severely pinched by the SGX cowl. Also included is the small diameter MAC header.
Pictures available of P&S and drum.
$225, money order only
