Replaced the transmission oil with Royal Purple Synchromax at 56K. It was getting pretty notchy. So far, shift feels smoother.

Any GP2 changed their transmission oil yet?

 

It is on my things to do list, when I am under there adding a short shift.

I am feeling the same notchy shifts as you are describing and was hoping to improve a bit.

Synchromax is the product I was looking at as well.
