oh, guru - help me out. i've read through a bunch of threads here and am still a bit confused.

on an 07 DX, with fatshots:
Right now, i'm running 9 discs, closed caps, all else is stock.
bike is running hot, and mpg sucks. i've tried 8 and 10, with little difference.

i'm planning to install a PCIII, and a better filter (either SE or K&N), and have it tuned at the dealer. i dont need it any louder.

Should i be using all 12 discs, and closed caps? or more? what setup optimizes performance, when one is using a fueler?

thanks

We obtained the best performance on our test bike with 8-10 discs and the closed end caps.
I would not go up to 12 or more discs until you install your Fuel Controller. At that point it will be up to you and your tuners discreation as how much exhaust flow you will need to match your Air/Fuel enhancement.
Until then, try dropping down to 6 or 7 discs.
