how to remove chain? 1975 honda cb 750

[Mikael Thallaug]

I need to remove the engine of my 1975 cb 750 and have disconnected everything I need to accept for the chain. What is the proper way to go about getting the chain off of the engine?

Put the bike on the center stand. Loosen the rear wheel and push it all the way forward. Pull the chain off the sprocket and remove the wheel. Take the chain off the front sprocket and it should either hang on the frame or be completely removable, either way frees the engine. you can then put the rear tire back on.

Unless you have a master link chain which you should not on a 750 you will need a chain breaker. You line up the tool with one of the rivots on a link and using an wrench push the rivot out of the link towards the tire until the link comes apart. Then just simply feed the chain off. Assembly is the reverse, you line up the new chain links and push the rivot pin into the link. This is much stronger than a master link chain since it is press fit.

There is controversy on this. I have used a master link and if installed correctly, it is virtually fail proof. As for strength, yes and no. The pulling strength is just as good on a master and that is what a motorcycle does. The side to side is not as much but then chains are not made to twist like that any ways. Also, the average 750 will not make enough power to even stress a master, not even on a 520 chain.

Also, the current chain I have on, even if the the clip DID come off, the side plat will not as I had to press it on anyways. I had to do this with my did roller chains as well.
I would speculate that most stories about clips failing has to do with improper installation. Such as the clip on backwards or not snapped on properly.

About the only time I would say a rivet should be used is in racing.

I would say that if anyone really has a question, go into a cycle shop and ask to see a chain with a clip link and then try to put it on with your hands. unless the chain is junk, it wont happen.
