Lots, but more specifically, what are you wanting from it? Because that's what the suggestions and advice will all depend on.

Bolt on stuff won't really increase your power much. They make better use of it's POTENTIAL power, but as far as gains, it's gonna come down to the guts.

If you don't have a stage one, that's where you should start. Intake, exhaust, and remap/rejet depending on fuel system. After that, you'll have to swap some guts to get any further.

You're next step will be to change out your Air Cleaner with something more free flowing. There are a ton of them out there to choose from - pick something that is proven and goes with the style you are after.

Since the EFI bikes are tuned lean from the factory due to EPA regulations and you now have an engine that breaths better with the exhaust and AC, this will make it even leaner (not good) - you'll need to re-calibrate or replace your ECM to ensure proper Air/Fuel Ratios throughout the RPM range.

I've seen quite a few FI bikes with stage one set-ups making 85 horsepower and 80 ft/lbs of torque - that's alot more than it had stock.

After that, if you feel you still need more, you'll be doing stage 2 stuff like headwork, cams, and pistons etc. These are much more complicated and you should have a final plan in place prior to proceeding with any changes because simply bolting on items without consideration of the other components installed could lead to a big dissapointment.

Take it slow and do alot of research before doing any mods.

SE Stage 1 air cleaner, HD RaceTuner, & pipes with a dyno will do the trick.

Willie D (above) summed up the horsepower bolt ons.

You could look to suspension bolt ons including tires.
A gearing change will also change the way the bike accelerates.

Else, camshafts and higher compression pistions will add a good HP increase.

To repete, it depends on what you are looking for.

Put better rubber on the road and practice. Best way to go faster everywhere but in a straight line. Just put 150 miles on a new set of Avon Venoms today and love them. Much quicker turn in, better road feel and quite sticky - even though the temp was low 40s.
