    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I'd be careful if I were you......Fredricksburg is close enough to Washington DC to be dangerous....especially when congress is in session!

Why does it seem that all chains have tight and loose spots? :? Also, is it possible that sprockets can be drilled off center? :?

In theory brand new chains shouldn't have tight spots. These appear as a chains wears the rollers wear a little and don't roll as well as they should.

I suppose you *could* drill a sprocket off centre, but for what pupose? It'd wobble like a great big cam lobe then!

I think that Clone means that id the sprockets were drilled off centre that would explain the tight spots even if you have a new chain, not try to do it on purpose. :D

I think that in this case the failing was on the recieving end... :roll:
 
I ask because it seems that even with a new chain and sprockets there still seems to be a tight spot. so I was curious.
thanks for replying. 8)
 
I think its improbable that sprockets could be machined off center enough to cause the chain to go tight in spots considering the amount of slack that is intentionally allowed in the chain/sprocket combination. I have removed chains and checked them one link at a time for freedom of movement, and I can always find spots in the chain that are less free than others. Unfortunately, I have not come up with a way to increase the clearances on a peened pin and sideplate assembly. :-)

Oddly, the problem of tight links and jerky tracking has proven to be worse with the more expensive "O" ring chains than it ever did with the plain heavy duty chains. Consequently, I have decided to stop using "O" ring chains because I am not happy with their lack of smoothness. When the "O" ring chains I am now running start to show wear, I'll be replacing them with non "O" ring chain and adding Scott automatic oilers to my bikes.
