Chain

[Sarris]

My GZ started making a shenka-shenka noise while driving steady under power this week and my mechanic discovered that I had a bad chain (with several very worn out and loose links), and that my rear hub internal shock absorber (cush drive rubber) was heavily worn and had too much free play (slack). Ron Ayers supplied an OEM hub rubber for $19.26 shipped and I bought an o-ring chain on e-bay for $49.50 shipped (vs. $100 for an OEM chain). I only have about 13,500 miles (mostly city driving) and everything has been serviced every 3k miles.

He also said that he thought that most aerosol chain "lubricants" do a very poor job of deeply penetrating the links and should not be used as a substitute for a good oiling (with good old fashioned clean motor oil) at every other 600 mile chain maintenace interval. He mentioned that this may be the cause of my premature chain failure, but he's at a bit of a loss for the cush drive rubber failure.

I'm wondering if anyone else has experienced either of these two problems as both seem to me to be a bit premature.
