Its just that your first post was alittle misleading thats all. I am in the same situation you are in. I have not touched the interior of my motor at all but, I have added just about every bolt-on, and (less weight) aftermarket part there is to put on the bike. It has made a tremendous amount of difference to the performance of the bike.
I appologize for the rude reply to your post but, it just seems that there are alot of riders out there that are either afraid or ashamed to admit what all they have had done to their bikes. Experienced riders can simply read / listen to said dyno numbers and know for a fact that there has been something done to the bike, thats all. I didn't mean to hijack your post so....Good Luck with the info you are trying to find out about.
