Problem

[alex27a]

Hello!

I have a problem with my busa... It manifests like this:

at 2000 rpm it looses power
at 3000 rpm it has a blast of power (compared to the power since then)
when I keep it constant at 3500 rpm busa has problems running smoothly and it accelerates/deccelerates quickly...

All of these are very annonying ... I changed the spark plugs, cleaned up the air filter (got a k&n), changed the gas filter, syncronised the valves, checked the compression (which is ok), removed the power commander, but it still makes these problems.

Does anybody has any ideea what it might be?

Thanks.
Best Regards!

P.S: I found out later that this message might be offtopic here, but I can't delete it. Sorry.

okay...wait a minute here....i just quoted myself as what i got to thinking is....

at 2,000rpms?....it's weak?...and then a blast of power at 3,000rpms?..

wtf?...my monies on...

"ENGINE LUG"

dude...the busa is a beast but it's also cogged kinds tall...either pump up the volume or go to a 42T rear sprocket.

Thad be my best guess.
