Back when I did this to my bike, a few people were curious how much power difference it made from my previous set up. Short answer, not much :???:

I was running:
40 pilots
120 mains
Factory Pro needles (4th clip I think)
Airbox w/ 5x 1.5" holes

Dyno said 74.1 RWHP - a nice jump from stock

Now running:
same pilots & needles
130 mains
pod filters (no airbox)
custom 3-1 pipe

Dyno says: 74.87 RWHP - gaining a whopping .76 over the previous set up. Sigh.

However, I am no longer too rich at low throttle, and I have a significant lean spot between 4-5k rpm... which I *think* means the needles need to come up a notch - more gas earlier.

On the upside, the pod filters do just fine in pouring rain... as I found out on the ride home

I still have some s3 cams to drop in as well. I'll let you all know when the next dyno run comes around...

Thanks for the update Crosstie. Tuning info is always appreciated.

Did you get any torque numbers?

btw - What size are your pilots - really?
