I used Valvoline dino motorcycle oil on my VStar two oil changes ago. It made a mess of the shifting, so much so that I thought there was something wrong in the transmission. I switched back to Yamalube (non-synthetic) and the shifting is like butter.
I used Castrol Actevo 10W40 in my M109R Suzuki Boulevard and that did wonders for the shifting. Its a semi synthetic which is part regular petroleum based oil mixed with a synthetic, its excellent oil and never had any problems with it in the M109R and I always rode that bike like I stole it. 35000 miles when I sold it and bought the F6B and it still wasn't using any oil.
