Yes i went back to the stock one because the lengthen one was worn out,but i use a different perch and lever to make it easier to pull in,seems to work fine,i did have the gearbox etc all polished inside to make it change gear easier ,that helps,plus a kx250 07 gear lever which is about 5mm longer to help with the swing of things,just as well you dont have to use the clutch much on a k5.
