what can be done to lessen or better yet, eliminate the clunky up shifting of these Ventures. I, however, shouldn't assume all lst editions have clunky shifts. My last 88 was fairly smooth. I have brand new fluid in the clutch master and completely bled out all the air; lots of handle. Brand new 20/50 Yamalube oil. I know that isn't the best but I didn't want to put $12 Amsoil or something equivalent right away. I intend to put a few hundred miles on this dino before changing to a better oil. But sure seems like this oil would be conducive to smooth shifting. Any advise would be highly appreciated.
