engine sprocket noise, and wear out
I have a problem with enigne sprocket. Ive changed to sunstar 431 - 15, did 525 zvmx, and JT rear sprocket. when installing engine sprocket, it's outside with markings. After installation I heard sweek noise from front sprocket. I disassambled again it and here is what Ive seen. After 50 km, there is wear out on brand new sprocket (inside side- from the transmission). Also see black grease with powder from weared off sprocket on chain. Outside was not touched. Ive then decided to reverse sprocket sides, as they are not same. On markings side there is little collar 1-2 mm. But reversing, noise was the same, and then outside side was wearing off.... Noticed black mixture of grease and weared sprocket powder now on outside side of the chain. Can this be wrong sprocket?
