I am replacing my sprockets and chain and I adjust chain tension as it says in the manual to 48-58mm (1.9-2.3"). I just read an article in dirtrider magazine where a race mechanic adjusted the tension to 1/4-1/2" slack with the rear shock compressed to the tightest point of chain tension. i.e where the sprockets and swingarm link line up. It seems to me that it is too tight. Is that for race bikes only?
