Transmission Issue/Gear 2007 GSXR 600
 

Hey guys, I need help... I am having trouble on my new bike… I have a 2007 GSXR 600cc, everything is running well until I hit 600 miles mark… since then… when I shift down from 6 to 5 gears or on any gear... for some reason it wouldn’t shift down…if anyonehas had the same problems input would be greatly appreciated.
