[QUOTE="Mudboy, post: 160287, member: 16856"] I had an '00xr400. If you really crack the throttle open at low rpm they will bog. Correct me if I'm wrong but I think they have a CV carb? So it has to build a little pressure before it lets the gas in. The richer the jetting the more the bog, the leaner the more it goes away. The answer is to clutch a little or give it a little roll before you snap it open. W/O changing to a pumper carb you won't get the response of a yzf or a 2-stroke. [/QUOTE]
