THE GEARBOX SELECTOR SPRING IS BROKEN AND THE GEAR SHIFT LEVER WILL NOT SELF CENTER, ALL THE LINKAGES ARE FREE AND WELL OILED ITS A 2001 BOSS HOSS 2 SPEED OUTO

check it is not a selector
gear cable or internal gearbox syncro problem

did not think the shift stick goes direct into the gearbox

gear selector inspection
remove the console around it

see if the bushes are broken

There are three posibilities for this worn linkage on the gearbox the linkage under gear lever or a broken mounting on the bracket where the lever comes up through the floor as long as you can get all gears it will be exturnal linkage fault.

Follow the shifter reach rod that runs from the shift lever back to a short lever on the transmission. Take the nut off and take the rod loose from this short lever. Then, move the forward like you are going to shift into low gear but don't actually shift the transmission into gear. Feel for the spring tension. Then, move the lever backwards and feel for the spring tension there. Check the shift lever and the reach rod for binding. If you don't feel the spring tension trying to return the lever back to the center, it's likely that the shifter pawl return spring is broken. This spring is what returns the shifter lever back to 'center". But,the temperature of the transmission will not change this. If the spring is broken, it's broken cold or hot. If the spring is good and there is not bind in the linkage, the problem may be in the shifter cam mechanism inside the transmission. Either way, this is an internal issue in the transmission.

Good Luck

First check the screw in the shift arm that exits the transmission. If it's come loose consider a dab of locktite. You can also try replacing the gear oil with a high quality synthetic product. Many claim that this makes shifting smoother, and if you are in a hot climate and also pulling a side car, then I would use a synthetic 80W145 transmission oil. If the bike has many miles, I'd look at worn gear selector mechanisms - starting with external linkages, and then, if needed and only after checking everything else, the internal ones. Alternately there's a chance this could be from a dragging clutch. If the clutch is worn, or if a spline lube is due, then that might be the culprit. Many basic problems and solutions are common with BMW airheads (which is what I own) so you might find lots more information and suggestions at those websites. This might be a good place: http://www.airheads.org/forum/technical-discussions

your problem with the gear selector is in the item 25 these are 2 plastic bushings that wear out and cause the gear selector feels loose, you should also check the item 27 this item has one or two screws loose and cause the gear selector feels loose

p[robably neither but a broken return spring on the selector lever

gear shift selector roll pin that holds shift lever in postion shift rod shift rod pivot and spring assembly, colomm retainer assembly pin for shift lever lower and shift linkage lower.
