Light cleanup work won't do jack to change the powerband. It may add a smidge on the top-end, but won't move the effective power up or down any significant amount.
Maybe the exhaust was slightly more than light but the intake was very minimal.
[QUOTE] I'd say that the low compression combined with the lean jetting is killing your bottom end. Er, your bikes bottom end. [QUOTE]
OK matt first I hope your winking at my four wheeled friend:)
Second this does make sense:o

I believe the same jets used in an FCR will work in the stock carb, and I'm positive that you can go at least to a 185. I've seen over 200's used in FCR's, so there's plenty of room to go.
OK I still need some help with where to find the jets.

The stock cam will offer the most bottom end. The 479 should offer more torque than the 450/451, but not like the stocker. The more mild the cam, the more bottom-end.
Ok this is where I need to give some attention. I do like the boost to the mid and top as it gives the bike a good feel in these rpm ranges. It was way to bottom heavy before :D .
I am thinking to try the stock cam with a valve job first before doing any cam work to see if it works out better for my type of riding. (I am getting into some hare scrambles in the so I still want to keep the bottom end)
The change in the mid and top did feel like they would help out in the woods. I am hoping if I get the CR problem under controll it will boost the bottom enough to make me happy and let me move on to getting confused with suspension upgrades.
