Not too bad an idea. But not a good idea either.

I have done it, but it is not recommended. Everytime I have had a chain failure, it was at the master link. So I imagine that two master links really increase your chances of failue.

I had a chain come lose on my first bike, a Honda SL 100. It was a new chain too. The master link just failed even though the tension was correct. This was shocking to me cause it exploded the counter sprocket cover dumping itself on the road.

I have had other chain failures on dirt bikes and the like. Again it was master link failure.

Real BAd idea, I got a mate who came limping into the motorcycle shop, we kept on asking him what was wrong, but he just hobbled in , bought some parts and hobbled out again.
This went on for three weeks, it bugged us and and all the mechanics decided to interogate him next time......which we did, turns out his overtight, botched two master link chain busted at over seventy MPH, it whipped his toes real good.....BUT he was so scared to go to the hospital,that he didn't, well not at first.........he limped and hobbled and was very afraid.....untill, he "showed" his "bad toes" to us.....
IF, you have ever seen films like "scot of the antartic" or "shackleton" or any of the "I went to antartica ill equipped and my toes went black" sort of films, then you have a good idea of what this guys toes looked like.........
it was lucky he did show and tell us, because someone recognised the smell of gangrene,
and he was kidnapped immediately and taken to A and E were they amputated three of the affected toes, if he had left it any longer it would have been his leg, without any doubt at all.
Upshot was, he had a bastard of a time changing gears on his bike for ages, untill he got used to the lack of toes........
the chain, would have cost less than twenty of our pounds........
Choose carefully,  new chain or a few toes? Hmmm hard choice eh?
In my own experience...
It wasn't a Previous Owner who didnt know what he was doing that messed up your bike, it was The Previous owners mate who THOUGHT that HE did.

well that sounds like some seatbelt class to get rid of a ticket stories type of #$%* there. not that it's not possible, and i did ask the question, but is that likely or just possible? asked the guys at the local shop, and they pretty much said the same things...divided in half pro and con. i'm sure i'll just buy a new chain when i get back from tour in six weeks, but in the meantime i just safety wired my two master links.  :-\

The "clip link" that I ordered for my new chain is the two outer plates with pins attached to one of them and of course the retaining clip.  There is no inside portion of the link (the part that the pins go thru)  When you need to add a link you will need this inside portion too. . . . So I am wondering if you will be able to get a "master link" that will actually allow you to do what you want.  Good luck

That's funny. I had that exact same thing happen on my first bike. Funny part is that it was a 1970 Honda SL100...

I also have never had a chain fail anywhere other than at the master link. I have put a second master link in a chain when I didn't have/couldn't get a replacement chain. It worked fine. I don't know that I would do it unless I had to, though.

If you were absolutely sure that what you were doing was 100% OK, Surely there would be no need to ask? You cannot fool your self! theres allways that little voice saying "you know you shouldn't be doing this..Just to prove the point, do you normally drive along the road looking down at your chain every two minites "just to check"?? OR, have you been doing this more often since fitting two master links? Have you found yourself checking the chain tension EVERY time you stop and park the bike? (not that there is anything wrong at all with checking that often,) BUT, do you normally do that?
be safe. your valuable.

When I installed a new Regina "O" ring chain on my 750F they did not recommend even one "clip" type master since it's a 630 chain, they wanted the master to be riveted and supplied only that type of master in the chain kit.  As a result I had to buy a nice $100 chain riveter tool and it worked like a charm .... really nice tool and I feel very secure the chain will not fail.  The tool is expensive so I would be more than happy to install a rivet style master on your chain for the cost of shipping back and forth, if you wish.  FYI

is this a bad idea? had a 34 tooth sprocket, went to a 37 tooth. added one link, and another master. bad idea?

Here's something to consider.

A rivited type master link is only about 90% as strong as a continual link chain.

A press fit clip type master link is about 70% as strong as a continual.

A loose fit clip type master link is about 60%.

Something to think about.

rode a couple of days on it, and now it'll sit for 5 more weeks. i'll replace it when i get back. yeah, of course i was worried about it--that's why i asked the question...but that goes for everything on this bike, as i just put the whole thing back together. i look at every nut and bolt everytime i get off and on it.
