I jett'd the '98 to get rid of the flat spot - I hated it. Crack it open, and it'd take off, pause for a moment and almost throw me forward, and then take off like a bat out of hell again. After jetting it with the factory pipes its as smooth as can be from 0 to redline. Its a nice, constant pull with no flat spots. Thats the reason I jett'd mine...
Same thing for the Magna, and VFR.
