Has anyone had trouble with the bike running rich on yamalube? I had been running maxima synthetic with no fouled plugs and bike ran good started 1st kick everytime. I switched to yamalube with the same ratio, 42:1 and have got 2 fouled plugs within 1 tank of gas. It just seems to be running richer. Any thoughts?
Thanks

I have ran yamalube 2-r synthetic in my bike since purchase and love the stuff. Just put piston and rings in the bike after 2 years of heavy riding and internals were very very clean. On top of that I have never fouled a plug in my bike. Nothing buy thumbs up on Yamalube 2-r

What is the difference between the Yamalube products 2-R and 2-S? I realize the 2-R is the good stuff, but I was wondering what exactly is different in the formulas.

When I first bought my bike (in 2003) I ran Yamalube. I fouled plugs like it was going out of style. I switched to Amsoil and I haven't fouled a plug since. Now that I've learned a lot more about these bikes I know that the proper solution would have been to adjust the jetting, as the bike comes pretty rich for trail riding. Now, even with my jetting adjusted better, I still run the Amsoil though.

I don't get it. I ridden a yz125 for the past two years and have never once fouled a plug, and I don't even ride it that hard. I've used both Yamalube and Bel Ray H1R both with great results. I don't understand why do so many people seem to complain of 2 strokes fouling plugs.

yamalube 2r 50:1
I tryed 40:1 and 44:1 and was way to rich for me. The owner of my yz was running it at 40:1 and said he fowled a couple of plugs so I went with my previous experience. I went with yamalube because he was running it. After this I may go back to amsoil. Also I ride single track and try to keep fresh packing in my silencer.

Should I not be running the 2S kind? Thanks for all the replys.
What kind of bike? As the poster said above, 2S is for oil injection systems, though I have run it as premix in a pinch.
2R is their "high performance racing" oil and is the one you should be running if you are premixing, and definitely if you are running a modern bike with power valves.

I run it at 32:1 without any issues. Never fouled a plug and it don't spooge. Proper jetting and head squish is the trick.

I have a 2004 YZ125,a 2005 YZ250,a 1977 YZ100,and I run Yamalube 2R in all three of them at 32:1.None of these bikes have ever fouled a plug.Not even once. Running 2S may be at least part of your problem.

Try 2S at 32:1. 42:1 puts more gas into mix making it run cooler. Nothing wrong with 2S in a pre mix bike.

Then why does 2R cost more than 2S?
2R claims to be more suitable for power valve equipted bikes at least according to Yamaha's advertising.
I would really like to know the facts though. What, if anything, is better about 2R. Surely this info must be out there somewhere.

Eh, a 2S torn down motor is not messy and the motor does not blow up when 2S is being used. Use 2R if you actually race.

???
Are you saying that motors that use 2R are more messy and blow up more that those that use 2S?
This seems completely backwards. Why would anyone use 2R then?

No. I am saying there's nothing wrong with 2S for purposes other than racing.
