zerorev3rev4 Posted August 5, 2014 Report Share Posted August 5, 2014 sounds like return spring broken or not working Quote Link to comment Share on other sites More sharing options...
lineaway Posted August 6, 2014 Report Share Posted August 6, 2014 The rivet itself could be coming apart. Back in the `old ` engine, just take the clutch cover off and it is probably an easy fix. Also the shift shaft could be bent. Quote Link to comment Share on other sites More sharing options...
thats_a_five Posted August 7, 2014 Report Share Posted August 7, 2014 In that gearbox there was the shift pawl that pulls or pushes the shift drum. The shift drum has pins that protrude. There is a roller that pushes between the pins to ensure proper engagement. Both the pawl and the roller have springs to position them properly. These springs weaken with time, also there was an upgrade done to a stronger spring. It sounds like the spring on the roller may have broken. I would recommend changing both anyway. The parts are not expensive. Certainly check the items suggested by others because they are right in the immediate area of the springs. . You do have to remove the right side cover and the clutch and basket to have good access to these. Quote Link to comment Share on other sites More sharing options...
