I bought new parts for a camchain swap on my R65GS from motorworks. The sliderail I recieved appears crooked on the sliding part of the rail - does anyone have thoughts on this? A cheep sliderail to be thrown in the bin? I haven't done a cam chain swap or looked at these parts before so I don't know if the original slide rail is okay for a reuse and also if the crank sprocket is worn or not? Please enlighten me on wear patterns on cam chain parts.
