The reason I think it may be linkage is this: Drove home ok, went to unload my bike and the hill was to high, pulled over to another area and wouldn't come outta 1st, started feeling some bending on the shifter tube so before I broke it I pulled it out, took it to work had the crack welded up put it back in and it was working fine, while doing all this the linkage seemes really sloppy and it has a very long throw, (bout a footbal field in length). And went for a shrot drive 'rounf the neighborhood last night and now stuck in 1st again.

If its not linkage I'm afraid its gonna be the throw out bearing.
