I noticed today while mowing that when first setting for 4th gear there seems to be a gap between 4th 5th and 6th. What I mean is that it felt like it was in gear, but when I let the clutch out it didn't move, but a light bump on the shifter and away we go. Seems like there is some slack between the higher gears. Shifts smooth, Clutch fully dis-enguages, and no slack once in gear, just seems some space between the gears. is this norm, or can it be tightened up?

PS, The rear rims would need cut off if I had to remove them.
