I've been slowly working on a little project. It could be used with the larger filter setup as long as the box was opened in the back. This prodesign kit with k/n slides right in. If you've seen the batteries they are .8lb and more then enough cranking amps. I also eliminated the stock battery box, vent canister, and soon the fuel pump will be in an aluminum tank. basically as light or lighter then a kicker kit. Its just mocked now, still need to finish everything, but the starter solenoid is inside the box, main fuse in front of it.
