Does that model have the powervalves?I have a 2000 GP1200R,& just installed a oil block.
What is the right oil mixture?
32:1(20oz to 5gal.)or 40:1(16oz to 5gal.)
I'm pretty sure that the recommended ratio for non-PV Yamahas is 50:1, and for the PV 800 and 1200s it is 32:1. I've seen this info someplace, but can't put my finger on it right now. You should be OK if you do not have the PVs to go 40:1 as a good starting point, then try 50:1 if all goes well.
