A friend was asking if I would build him a 4mm set-up. Sure no problem. Imagine my surprise as I popped off the reed cages and saw this.

The pistons are beat up- again surprising the skirts hadnt cracked- YET. Said it rattled and shook a little
more than he would have expected but he's a noob Banshee owner...so

Transfers are basically
stockish...they were smoothed a little, but no more width or duration added. Exhaust was jacked up to
194*...
