The mechanical reverse on my Yamaha RX-1 doesnâ€™t seem to engage or disengage like it should. Sometimes it lets out an embarrassing grind, making me look like an idiot in front of my riding friends. Are there any known issues I should be aware of? The unit isnâ€™t that old to be worn out or anythingâ€¦

It is most likely the linkage arms being out of adjustment. When you pull the lever and return it for forward operation, the internals are not getting the right amount of â€œthrowâ€ required for smooth engagement and disengagement of the reverse mechanism.
First check the upper (horizontal) linkage arm. With the reverse in the â€œforwardâ€ position, the upper arm length should be 27mm (inside length of threaded adjuster, between the lock nuts).
Second, you need to get rid of any free play in the lower (vertical) linkage arm. Loosen the locknuts and adjust it until any free play (up and down) is removed, then back off the adjuster 1/4 turn and lock the nuts.
Both of these adjustments must be right for the reverse system to shift properly. If all of this checks out, consult with your Yamaha dealer for the next step to remedy the problem, but usually itâ€™s a matter of these two adjustments.
