Default Valve retainer diameter

I'm curious if the 140 and up valve retainers are all the same diameter? I've become frustrated with installing the keepers and am working on a tool to ease the installation. If the 140 and up are all the same I might make some tooling and do a limited production run.

Thanks!

Ken

I don't know the answer to your question and suspect most modelers won't either.
But - I do know that just like Saito many different sizes of YS engines use the same parts. For example the Saito 82a & 82b use 65 cranks and 100 pistons and cylinders which means many other parts are the same also. In fact they list some parts as working for many engine sizes.
