Hi, I've got a 2008 WR250F and, apparently, there is a restriction on the throttle opening. Here is a link which describes the restriction and how to fix it http://motocrosshideout.com/free-mods-for-a-wr-250f-dirt-bike/ - although this shows an '07 bike, there are other threads indicating the same issue with '08 bikes
So, spanners out I've stripped mine down but before starting to find the offending throttle stop screw I noticed that the throttle slide seems to be fully opening and closing (see pics http://www.facebook.com/album.php?aid=31134&id=100000399335477&l=f0c88e50c9). Does this mean there isn't a restriction or does the throttle stop screw do something other than affect the throttle slide opening?
Thanks, steg
