[QUOTE="TexKDX, post: 133945, member: 16276"] Hello DRNers, I have a '99 XR250 and am riding it in the mountains of CO. I think I have it jetted pretty well right now. Mods are: airbox screen and snorkel removed, baffle removed, pipe welds ground out. Here's the problem: when lugging the motor on level ground and riding whoops, normally in 4th gear, the motor coughs badly when I hit the whoops. It will do the same thing in any gear if I am at lower RPMs and around 1/4 - 1/2 throttle and hit say rocks or roots. If I run a higher gear and scream the motor, then the stumble does not happen. It sounds like float level in some ways, but this does not explain why the problem is not there at higher RPMs as best I know. Any help would be appreciated. I'd like to be able to make better use of the torque available at lower R's. Thanks! [/QUOTE]
