I have 2000 r6 that I recently purchased a few weeks ago , I took it for a ride up to FairPlay co and the bike started bogging down . I got the bike home to find the air filter was really dirty . So I replaced it and still I had the same problem . Any way here's what I've done.
Replaced the air filter
Installed new plugs
New Oli n filter
Cleaned the carbs off the bike
Cleaned the jets out they are stock
Adjusted the floats


So the bike runs ok , slight idle roughness but I'm getting no top end speed my bike will only go like 75-80mi an hour and not pull any higher after 8000rpm any sugestions ? The bike originally from Iowa . Please help and thank you
