Who has a '00 400 EXC that chokes or bogs down when the throttle is twisted pretty fast. Surely for the praise that this bike gets, this can't be accepted. When the RPM's are up fairly high I have no problem. My wife has a '96 XR250 and when you roll the throttle it responds perfectly. What is the diff? Somebody please enlighten me.
