The Manual....It all in Japanese!!!!!!
Plus I just sold my 12r5 yesterday...Just don't feel like opening the shipping package. I'm trying to Acer ceramic bearing it the stock have too much friction!!!! I went ahead and ordered the acer 12r5 bearing kit plus a non flange 1/4X3/8 for the spur. The Yoke isn't using a flange like the r5 does for the spur. If it doesn't fit Acer is pretty cool about returns... I hate steel screws and stock steel bearings
