My Bike 2008 XB12R is having a shifting issue, Its acting like the return spring on the shift shaft is not returning between shifts, example I shift to Second, then if I want to shift to third I have to push down on shifter a little first before I can shift into gear. I have read all the forms and checked the return springs the Bushing on the Primary case looks good, the all new gaskets on primary and shifter and adjust everything to spec in the manual. I am at a loss here what to do next. I have had the primary apart 5 times now triple checking everything. The bike has never been dropped and the shaft is not bent. Could it be my inside primary bushing? Were do I get a bushing? Can I do something to my current Bushing to make it work? It was working perfectly before my stator had to be replaced. Any Ideas?
