Although I generally don't do a lot of modifications in the name of getting more power because I trade often and when I decide to pop for a new bike, I'm well aware of where it stands in the power delivery/performance category and I'm happy with that. I did sit down a few days ago because I was bored stiff with our winter weather (literally). I looked at the best full exhaust that I would go with (Akropovic) and not the most expensive of those, the associated Power Commander PCV and a K&N filter. Not a big deal because I'd done the same thing to several other bikes in the past (maybe with the exception of a slip-on instead of a complete exhaust system. The cost I came up with was about $1100 and I supposed that wasn't all that bad considering what I was getting as far as the components were concerned. Then I started to look at about what I might expect for my expenditure. The closest figures I could find as far as dyno results went were about a 3 H.P. gain at 9000 R.P.M. I suppose there are a lot of riders who would say that's OK, "I'm 3 H.P. ahead of the guy who doesn't add the stuff. In my more testosterone driven days when I did do extensive modding, we figured about $100/H.P. as a kind of guideline. These numbers I came up with are closer to $300/H.P. I guess what I came up with after my little numbers adventure was that the newer bikes are actually getting about as good as they are likely to get at the pricepoint we are getting them for and improving that is simply going to cost more, a lot more.
