I love the mid-range and top end on my WR450 but feel it is missing some low end punch. I am coming off a XR400 which is all low end so maybe I just need to learn a different riding style. I have the AIS removed, Jd jetting done, gray wire cut, throttle stop changed, stock pipe with the insert removed, snorkle removed. Questions: What other things can I do to affect the low end and which ones will give me the most gains for the buck? p.s: I would like to stay under 96db.
