Cams

SE255s are not my favorite drop in cams for the TC103, but a lot of guys swear by them. Expect about 85-90 hp and 100+ ft lbs of torque. They're somewhat limited by a very short duration.
If you do the install yourself, and pick up a set of low mileage takeouts for 125-150 bucks or so, and using your stock pushrods, you can do the swap for less than 200 bucks. Add a set of quickee adjustables adds another hundred or so to the total. Still, a decent set of cams may be one of the best bang for the buck upgrades you'll do for your bike, the stock smog cams are worse than horrible.
Pay a shop to do it for you, and you're likely looking at 600-800 bucks or more. It's an easy job for any half-assed home mechanic, though, and once you've done it a couple of times, you can knock out a cam swap before lunch, (easily done in a day, taking your sweet damn time).
If you decide to buy a set of takeouts, be sure to ask if they've been recycled through a second bike. There are enough takeout 255s from cvo bikes that you should be able to find a set that were removed when the bike was sold, and have essentially no miles on them.

On a stock bike I would chose the SE204. If you decide to go that way can give you a map for the PV that will work well. It have seen 255's upgraded to 204 and haven't seen a one that didn't like it. This is in 103's. In a stock compression stock head bike most of the bolt in cams will be real close together. The stock heads can only benefit up to .500 lift, beyond that not so much. The 204's are at .508 lift. Most of the bolt ins are at .555 up lift which doesn't make that much difference. Put compression and heads then the .540 up lift makes bunch of difference.

I second the SE204 cams, is one of the best out there that I have tried, you will like them much better then SE255's and they are a HD cam. The only reason I dont still have them in my bike is I went gear drive, HD does not make gear drive cams, the Andrews 37G has almost the same specs as the SE204, I have tried lots and they are my favorite.
