If you can then fit a properly riveted chain. However there isn't a lot of info about the suitabilty of a loose link as a lot has changed over the last few decades.
Like a lot of you I had the fun of boiling my chain in a tub of waxy subtance back in the 70's. Bikes were less powerful, you could argue, but a two stroke 500 or 750 put an awful lot of stress on a chain in the power band. Today's bikes are more even in power distribution. Technology has introduced O,X ring type so it's now fairly unlikely to make a loose link joint to match the precision/perfomance of a modern item.
What has been evident is that if you had to do it yourself, like I did on a Yamaha 600 once, you have to remove the swing arm to fit a 'complete' chain. No bad reason to grease the swing arm anyway but a potential money maker for the manufacturer.....
OK, it's easier to have the chain riveted on the bike but I've been a bit cautious about that in terms of quality of fixing anyway. Might it fail if not done correctly or if done badly might it be too tight and cause premature wear?
I suppose the 'book' solution is the best...........;
