  1. When doing valve clearances I know you have to allign the marks of the stationary pointer and the mark on the rotor, but what marks do I allign them to? Mine has 4 visible marking on the rotor. Looks like this >> | • | | <<

    The piston has to be top dead center ( tdc). check out the pdf service manual made available for download by @vixy in yzfr125 general discussions. Page 3.3 explains valve clearances and alignment marks.
