I was using a left-over bottle of Bel-ray 75W that I had laying around, but it made the kdx feel like shifting gears on a big rig. My foot was sore at the end of a 3 hour ride. Yesterday, I put some cheap napa 20W-50 oil in just to see how it would shift. Well, now it shifts like a dream. Tuesday i'm going to get some full synthetic 20w-50 cycle oil. Until then, the bike sits. Thanks for replying everyone. I did a search on transmission oil in the forums and was suprised by how much info I was able to gather.
Thanks again everyone!
