chain slack

Not anywhere near as clear a picture as whoops's but here is what i measured after verifying the rear wheel was in line;

Inside measurement on right adjuster;


Inside measurement on left adjuster;


Measured the inside to flat space and also the flat to outside of bracket measurement, both showed the same discrepancy of the left arm flat being 1 mm shorter than the right arm flat, the markings on the brackets seemed to be the same on both and have 5 mm intervals.


Here are the pictures of left and right combined which show the 1 mm difference;



My swingarm was made in 2010 so the newer ones may be a lot better but it pays to check this, the difference is a bit more than 1 rotation of the adjuster bolt.

And agree with jfro, provided your swingarm is the same length on both sides, i.e. better than mine.
