I left out that the website says to use Max Cycle 10w30 in the primary and Max Cycle 20w50 in the engine.
So I called Royal Purple this morning to find out the final word from them what you want to put in your primary.
They guy recommended Max Cycle 20w50 or XPR. From the website,the Max Cycyle appears to be the best for our tensioners. No pictures of the rest of the primary for reference. However if it protects plastic like that, I would think thats a good sign for the rest of the materials also.

He very specificly said to stay away from anything with anti-slip additives or anti-wear additives. Anti-slip is for the diff in a truck, they have wet clutchs in there that are designed to slip. If you get that crap on your clutchs they are also going to slip. The anti-wear will do the same thing. What he's saying is DO NOT USE ENGINE OIL in there, not even (perhaps especially not) anything synthitic. They have the anti-wear additives to maintain the life of your engine.
On a side note, not flame anyone, a lot of people are passing around technical info that may not be qualified to do so. Please everyone, stay in your lane or at least do some serious research and say "this is what I've found" as opposed to "this is how it is". I really like this site and have gotten a lot of info from it. I think the responsible thing to do is to make sure we are putting out quality info instead of what we think we know. For the most part I do believe we are putting out quality info, but the lesser stuff can really lead someone down the wrong road. When you surround bad intel with good intel, it looks that much more credible.
Now please, discuss at will. I am anxious to hear what other people are using and why.

Thanks for the research Bordsnbikes! I'm going to try some royal purple tomorrow.
Anyone want to share? Come on folks.
I run the 20w50 in both holes...no problems.
i'm a fan of AMSOIL myself, it's faily easy to find test results online to veify that royal purple, moble 1, or amsoil is the best for your buel depending on where you look. but the point is any fully synthetic oil is far better than your standard oil. when i went to synthetic on my dirtbike i noticed it didn't break down (turn dark) between changes which i did every 3 hour's engine time. i i've convinced myself i get 3 to 4 mpg better gas mileage on my buell. as far as extra cost for this type of oil if you do the math it's my opinion that it cost less per mile and you don't have to physically change you oil near as often. im sold on synthetic!
I totally agree on synthetics in the engine. It creates a better coating to protect your metal parts that makes them run smoother which equates to better MPGs and longer engine life. What do you put in your primary captain?
i use amsoil 20w-50 in my primary and 75w-90 sevear gear on my clutch side.
I have 20-50 amsoil in both.
So i have been thinking about switching my primary to 20w50 amsoil, i have it in the crankcase....is there any clutch slipping issues with this?
