Observations as follows:
- chain is 6000 miles from new, no problems, no wear or visible damage
- sprockets same miles, looking perfectly fine
- sprocket mounting looks perfectly aligned, all nuts tight
- chain slack adjusted as required, hasn't changed in over 1500 miles
Now please help me explaining this.
When I measure the chain slack at different positions by rolling the bike forward (she has no center stand) the chain slack is the same in all but 2 or 3 positions. In those positions (each plus or minus 2 inches) the chain slack is reduced to under half an inch. No other observations. Adding plenty of oil and let it sit hasn't solved the problem.
I cannot figure any scenario {other than visible damage to the rear sprocket) which could cause such strange measurements. And I have a hard time ditching a good chain without a plausible explanation.
Has anybody seen similar ?
