gear lube test

[03wr250f]

Found a pretty good comparison of gear lubes, while it may only be 75-90 and 80-90, and does not include 75-140 I think that conclusions can still be drawn, and lots of interesting information is in the study. If you are into reading college thesis style studies it is great, if not you might just grab your insurance policy for a good read, or skip to the end and look at the last chart...
