I am scheduled to be on the dyno @ 1030 9/12. That would be a good time, plus they may even be cooking dogs for lunch.
As far as opening up the breathing, the main culprit is the tiny pipe coming out of the header pipe to the plumbing to the mufflers. You can get some improvement with K&Ns but to get real improvement you need a decent header set up. It will be interesting to see the numbers my touring makes between last time and this time with just replacing the stock intake stuff with a RamAir.
