Hi All,
I have been experiencing the loud chain for a long time.
I thought so at the time.
Yesterday and today I worked on the replacement of chain and sprockets.
After disassembly of used (32000km) sprockets and chain, I washed them in gasoline.
I noticed that the front sprocket is unnaturally worn on the invisible side (from the inside).
I began to wonder why this happened.
I checked the play on the swing arm.
The test showed about 2mm play at the end of the swing arm.
Now I understand that the noise was caused by the chain rubbing on the front sprocket.
Which was due to a lack of alignment front versus rear sprocket.
BTW, in my opinion adding a shim or turning a bolt will help for short time.
I did the same in my Sachs MadAss last year and after 2000 km of ride the shim rubbed off and the play came back.
In my country it was not possible to buy Sachs parts, therefore i had to do a swing arm bushing to eliminate the problem.
That's my experience.
