[irrational]

Hi.
I have just been curious about getting more performance out of my R1100S.
I love it as it is (Only modification is the Van Der Linde exhaust system most of them in South Africa have).

But I was jut wondering a few things and thought someone on the forum would have the know-how to answer.

I spoke to someone that said the simplest way to get better power delivery, especially mid-range is a K&N air filter. But someone else said you run the risk of it not filtering properly?

I was also wondering if, one day, the engine expires if one would be able to fit say an HP2 Sport engine in an R1100S frame. I love my bike's look and feel, so would want to keep it and maybe do some modifications far in the future if I feel like it.
The R1100 engine itself? I do not know bike engines really, but are there changes like cams or pistons or con rods that would make a positive impact (Less for tracking, more for road use of course). Can you "modify" it into a 1200 for more torque?

Is there any value in fitting carbon fiber parts? Is there a significant weight reduction from that?
What about brakes? Mine has ABS though and I would keep that.

Anyway. Just a few things I was thinking about. In the end I probably wouldn't do a thing. The bike is awesome as is.
