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?
Thanks

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.

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.

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.
