I'm just a bystander watching this wild thread... but I'm gonna stick my nose in now.
Shakabusa, I think the statement above, from a post way back on page 2, is what has gotten people "up in arms". If you were responding to the post right above it, it appears you were disagreeing that lowering the bike, adding a larger rear sprocket, and adding hp (all of which you said you were considering doing) would make the bike harder to ride on the track. Everyone else DOES seem to think those mods would make the bike less effective as a track bike (and I agree, incidentally) so you are getting a lot of info thrown at you to try to support that position.
I think everyone respects a desire to ride whatever bike you want on the track, if you enjoy riding it - if you look back at all the responses BEFORE that post, everyone basically said that if you love the Busa, ride it and have fun! If you are looking for something that will perform BETTER than the Busa - well, you'll get lots of opinions on that, but the "best bike" will depend on the rider size/skillset/budget, the type of track, and a whole lot of other factors including personal passion for certain styles, motors, brands, or looks - there is simply no single answer and if you can swingit , there is nothing better than finding a way to ride a lot if different bikes and feel the differences for yourself.
You mentioned before, that you don't know how to quote other posts - in any post you should see a "Quote" button at the bottom. If you click that, it will include the entire contents of the post you are responding to, at the top of your response. If you want to only quote part of it, just delete any of the text that is between the bracketed "quote" words that are at the beginning and end of the quoted text. DON'T delete the part that says "quote" in brackets at the beginning or end, though, or it will give you an error.
Hope that helps...
