yeah drain the coolent and oil, pull the lower hose of the side case pull the kick starter off, then remove the screws holding the side cover on, after removing the the screws pull the side cover off, watch the top area buy the water pump cover cause there is a tube with an o-ring that slides into the side case, becareful not to bend or mangle the tube removing the cover.after the cover is off look down under the clutch backet towards the back and you should see the shift shaft end if there is no pin coming throgh the shift shaft linkage then you found the problem. let me know if you need anything else always glad to help.
