I have a Y1 tranny with no grinds but it is missing the tailhousing PLUS a Powdercoated YS1 tranny housing and all of the gears/guts for it. You can just put on the powdercoated tailhousing and have a perfect Y1 or put together the YS1 or get a tailhousing and put together both. I was in the process of building a tranny, but now I'm outta the scene. ONLY $250 for everything!!!
