Just had 5k service done went with Mobil 1 V-twin for crank, Redline shock in the Trans, spectro primary chaincase in primary for now. Gonna try spectro 6 speed trans oil per Glider on next service. Must be something in it special. I had Lucas 20w50 in crank, Lucas gear oil 75w145 in trans, spectro in primary for 1k to 5k.
