had this issue a few times now, seems worse when it is hot. ill be riding along in 3rd gear and try to downshift into 2nd but it gets stuck between gears, almost like its in neutral. it has caused me to fall twice now, both times on fairly steep hills. its very hit or miss though. new years in glamis running the bike very hard it would do it 2 or 3 down shifts in a row but then some trips it will work flawlessly all weekend. its "missed" a shift maybe 15times total now. it annoying now as im always thinking about when im getting ready for a dune or hill climb. anyone have any idea what it could be? 2004 XR400 with relatively low hours.
