I was tightening my chain up and noticed that when i got it where i wanted it and then spun the wheels around that it would get tight and then loose. I checked all the teeth on both sprockets and they look fine. I can t see anything that would be causing this. any answers would be helpful....thanks in advanced.

 

It is normal for a chain to have a tight spot, but not drastically tighter.

 

ride it a little to get chain warm//then oil it with good chain lube..that should end your troubles!!

 

The same thing was happening with mine, turns out the bearing in the consentric where bad. Changed them and no more problems.

 

That happened to my old TBlazer, and the dealer said it just had a tight spot in it, and to check chain tension on the tight spot when adjusting the chain, because it was worse to have the chain too tight then too loose......Latah.......
