Get a pipe, filter and tune it with ecmspy or buy an EBR ecm. Good gain from those. Xopti is the guy you want to deal with for a tune www.xoptiinside.com or http://thetuniversity.com/
Or do it yourself with ecmspy or tunerpro if you are good with that kind of stuff. Mine needs to be tuned real bad.
2005 Buell firebolt xb12r. While I have rode a bit before this is all a new world to me still. My second run was 1.3 seconds and almost 10mph faster. I can guarantee the times will keep dropping and the mph goes up.
with that mph Id say you have a bit of room left to go. Just get more seat time on the bike and I think you could go 7.70 at 92 ish mph. I started off running 8.10 now im at 7.40 at 98mph on a 600RR. And I still have a bit more to go.
