Hey guys, I have a (new to me) '02 WR426F and I rode it off-road for the first time last Friday down in Baja. What a frickin' rocket! This bike is amazing! So much fun to ride. It seems to have a never-ending powerband, which I found out by almost looping it off a little knoll jump because I opened the throttle too much on take off. Anyway, I have questions about why the carb doesn't seem to be working properly on decel after the bike is fully warmed up. The bike has had all the mods done to it before I got it, including richer jetting, but I don't know what the sizes are. On deceleration (closing the throttle completely) after running at high speed, the engine rpms do not drop fully when slowing down or stopping. It doesn't allow the normal compression braking that I'm used to with large 4-strokes. It will eventually come down from this "temporary" fast idle after about 10 seconds after being completely stopped (no forward movement). What do you guys think would cause this? Does this sound like an incorrect idle screw setting, maybe too high? Is the fuel screw out of adjustment? Could it be the wrong size pilot jet? Or is there something wrong with the slide? I'm new to the Yamaha world and have no experience with flat slide carbs. Not having the engine slow the bike down when I let off the throttle has me a bit concerned. Any feedback is really appreciated.
