My top case had stopped locking. I have found after taking the mechanism cover off the red shaft is twisting in the middle instead of sliding the lever across on the bottom. I removed the rod and locked it manually and the mechanism didnt seem to be in any sort of bind. I only needed for backrest support on my last ride for my wife but have a long trip comming up in three weeks and this case will be loaded making digging for the slide a problem. Anyone know what could be casuing this or where I can get another shaft. I have thought of twisting this shaft until it looks straight again or a little beyond straight and leaving it for a vew days to see if it would work again. Seems this piece should have been made of aluminum or steel.
