RE: 2007 cam choise
The 211 cam is a decent cam when it comes to power in a 103 it will work fine get the comp ratio in the 10.5 range and you will be fine. Since the 103 is using a stroker crank you will make good low end and the cam will come on nice in the 3000 range and pull from there. In a 95 inch they tend to be soft on the low end unless you really stack the compression, but not true with a 103 due to increase stroke. a decent choice for a SE stick, I would also look at the 257 cam in the 103, head work is always a plus and will make a huge difference in the overall performance of the bike. I would use a smaller intake with the 257 like a 1.9 valve and use a 1.615 onthe ex to help out with that 257 cam with a good compression ratio in a 103 making 108+ on both hp and tq is a walk inthe park with a good exhaust system.
