Drive Chains

[michael1954]

I do not know if this has ever been discussed here, I could not find it.
My question relates to Drive Chains. Do they have to be one continuous chain, no master link added, or can you buy a new Drive chain, and join it with a Master Link.
Question arises because the Clymer Manual says the Drive chain on the GS 750 needs to be the OEM continuous chain with no Master link added by the rider. I have never heard this before, but that is nothing new. I was hoping it states this because in 1980, chain master links and Drive chains were not that good. I bought a good Drive Chain with a Master link from a company that makes Drive Chains for many different bikes, with two new sprockets. In the old days we always replaced both sprockets with a new chain. But on my Suzukis in the late 60's/early 70's, we used Master links.
I need some advice on this one, please.
