Did you guys and/or gals find that switching to synthetic helps the tranny shift smoother?
I drained just the tank and put in sythetic yesterday, just as an experiment, and it sure seems to shift alot smoother and quieter.
I think 20W is too heavy for the bike. I worry about the bearings and cams not getting enough oil quick enough when cranking. Also, I think BMW ended up changing recommendations to 5W oil so that enough oil gets to the clutch to keep it adequately lubricated.
Man, the shifting is a dream compared to dinosaur oil. I just click the shifter up with my big toe, after preloading, and it usually goes in with very little or no noise. Life is good, and so is the bike.
I have filters on the way and am going to try 10-40 syn. with filter.
