Default 103 Performance Mods

Have a 2010 RK 103 Police with Rush slip ons.
Looking to boost performance (aren't we all?). Figuring some cams, power pack and air cleaner are cheap ($1500) boost. But will do more if there's better bang for buck.
Don't want to re-invent the wheel.
What has worked for you?

You had better check the Fuel Moto 107" kit. Big power for sure.

I would definately consider a FM-107 kit if upgrading from a 96, but not so much from a 103. I guess that 4 extra ci is just not enough for me to go that route. I say just do a Stage 2. You already have slipons, so pick up some good headers and cams. The wood cams seem to be one of the best.
My Precious: 2011 Road Glide Custom 103 (vivid black)
Performance Upgrades: V&H Dresser Duals and V&H Twin Slash Rounds, Screamin Eagle Air Cleaner, DynoJet PCV.
Other Upgrades: 13" WindVest, 10" PYMB, Hog Tunes, HD Chrome & Rubber Grips, Kuryakyn Dually Highway Pegs, HD Streamliner Passenger Footboards.

Good set of head pipes, cams, tuner, maybe a little head work if you like, and your set!

Well a lot depends on what you plan on doing and what rpm's you ride at. You can see what I have done and the dyno results for my bike below the pic. I ride in the 2500 to 2700 rpm range that is where I needed that extra kick in the pants if needed. I am all about the torque don't need those high horsepower numbers.

08 Ultra, Rush 2:1 Wrath Performance Exhaust, HD Oil Cooler, Stage 1 A/C, SEPRT, T-Man 555 TQ Cams, 103 Big Bore, CNC Ported Heads, .040 head gasket.

Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and proclaiming, "Wow, what a ride!!!"

Some nice bang-for-the-buck options:

1. Slightly used 255 cams bought on Ebay: $200-300 total if you DIY. Wood 555 or SE204 cams would also do well in your 103 with its standard 9.6:1 compression. Add $150 (SE) to $250 (Wood) for new cams.

2. Fuel Moto Power Package (PCV and AC) minus the mufflers: ~$400 (IIRC). Buy the Jackpot Dyno-Tuned baffles (~$100) for your Rush mufflers for a nice all-round power boost.

3. Head-pipe upgrade to get rid of the cat, if your bike has one. Fuel Moto makes one and sells other brands, too.

Stage 1: Fuel Moto Power Package, SE255 cams, Power Vision
