if you know the chain is good then you KNOW that one of the sprockets is not. The most likely suspect is the rear sprocket; worn, off center, or both.

I think that is about normal. My chains have always had tight and loose spots on them. Even on bicycles including my sons John Deere pedal tractor :wink:

chain tension is measured with bike on ground and sitting on it. should be about 3/4 inch to 1. roll her around a bit to make sure. If your going on atrip with your lady, she has to be sitting on her too. plus all luggage incl. hairdryer. Heh, heh, ride safe my friends. Ol' Poop cole

It's pretty common to have a tight and a loose spot on a chain. An old mechanic friend of mine explains that it's usually from a bent mainshaft.....
Be sure to set the slack at the tightest spot in the chain, with the bike on the ground and the passenger load similated. You can have someone sit on it....
