Every where that it counts anyway - low end, high end, mid-range, and everything in between. I'm actually a newbie to the four-choke world with my '01 YZ426F but loving it more every day! I would have never even considered buying a four-stroke bike (I have always been two-smoke brat) until my neighbor bought a Raptor and let me ride it. After seeing how easily it revved I was hooked ;~). Anyhow...... ------------------ jason s.
