are you meaning from new ? as in from the factory ? I've had a 125 that I've rode approx. 45 mins with no issues, then another 15-20 mins and piece of what appeared to be "welding slag" was found in the slave piston area, seal was toast, and it beat on that end of the slave cylinder...enough to warrant replacement... I am trying to understand how anything could be in there from the factory ! I've never heard of it before on a new bike anywhere...
