Upt North same is happening on my bike... not that bad though, I mean a few less rubber rings inside the cover and some more are popping out of the chain... ZVMX the chain, JT sprockets...
I bought an alignment tool to check the wheel alignment, even if I always spend a lot of time to be accurate when
adjusting the chain slack...
alignment was OK by the tool too.
but I noticed a little freeplay on the wheel, the right hand side bearing failed, changed all three bearings,
I believe the freeplay was that little that didn t cause the failed rings
the chain-sprocket set has a 9000 miles life already , I hope to last as long as possible
I always was using these brands in the past on my thou superbikes and was always happy,
but that s the last, my next will be a set of RK, AFAM or EK
p.s. all the popped out rings are on the inner side of the chain
