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.)
Does that model have the powervalves?

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.

OK I found the info on SBTs forum:

Post Pre-mix stock oil ratios

If you have removed your oil pump and gone pre-mix, these are the correct ratios you should be mixing to, after the first tank of break-in. These are the stock ratios the factory pumps put out at WOT:

32:1 = 4oz/gal
40:1 = 3.2oz/gal
50:1 = 2.5oz/gal

Sea-doo
40:1

Yamaha
All but 800 & 1200pv 50:1
800 & 1200pv 32:1

Kawasaki
50:1

Polaris
40:1

Tigershark
40:1
