Oil Mix

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 don't know for sure but I think 40:1 is the way to go. 32:1 seems too excessive

Since you have already undone oil injection (????) not sure why, but until you know the mix is right I would go 40:1. It may be smoky since at an idle oil injection is about 100:1, then changes the ratio through out the power band. So by premixing the only time you are at the right ratio is at WOT. Which most two stroke engines are a 50:1 ratio.

Good luck with trying to balance it for all speeds without fouling plugs. You may want a gas mask for start up. They invented oil injection for a reason......

Everyone that is familiar with this unit knows that one of the main problems is the oil lines come loose & many have blown their engines.
I've done my homework & talked to a few owners.

So instead of replacing oil lines we go backwards in technology and emit more pollution??? Bummer Yamaha

Anyhow,back to my original question.
Would 40:1 be the right fuel/oil mix?

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

Your 2000 GP1200r is a powervalve motor so run 32:1 Now I know why my 98 GP1200 just barely sipped the oil. It ran at 50:1. Good info Ernest.
