61x cylinder

    (Yamaha 650 cases with different intake ports welded on)

    Need some help here. Rebuilding kind of a weird old school specimen right now. 6m6 cases, 61x cylinder, dual intake ports welded on and a custom made intake manifold with dual 42mm sudco cdkII’s. Oh and a genesis head and protec pipe. Weird setup but it rips in my fx-1. Anyways, I need to know...

    Where to get Cylinder Bore

    I didn't really know where to post this or if you guys would know but here goes. I bought a square as a project and the motor was full of water. The carnage wasn't that bad, mostly surface rust. So I need to bore the Cylinders (61x). Would any of you know where I can get that done around buffalo...
