I'm replacing the cam chain on my '73 CB350. I didn't want to split the cases, so I'm trying to use a cam chain with a master link. The EK chain I have came with a rivet-type link that has solid pins. I've tried two different kinds of riveting tools, the MotionPro cam chain breaker/riveter tool, and the MotionPro heavy duty chain riveter. The cam tool is designed to rivet hollow-nosed links, and will not work for mine. The heavy duty tool is usable for solid pin links, but will not work with a small cam chain. I think the chain is a #219. Does anyone know any tricks or a way to successfully rivet one of these master links? I've already ruined two links, and I want to get my bike back on the road. Thanks.
