Primary Oil Discussion

[Bordsnbikes]

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.

I left out that the website says to use Max Cycle 10w30 in the primary and Max Cycle 20w50 in the engine.

Thanks for the research Bordsnbikes! I'm going to try some royal purple tomorrow.

 

[Bordsnbikes]

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![up]

 

[Bordsnbikes]

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?

 

[captain13ron]

i use amsoil 20w-50 in my primary and 75w-90 sevear gear on my clutch side.

 

[Roccodart440]

I have 20-50 amsoil in both.

 

[06Xb12R]

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?

 

[Phrogg]

I was told from a buddy who races his buell to put amsoil 20w50 in the primary. Which makes me doubt there would be any slipping issues with the clutch.

 

[blackedout]

I have amsoil 20w50 in both and am very happy with the clutch, shifting and engine idle. Very pleased all the way around.

 

[teh Nub]

Amsoil 20w50 in both... I'm happy...

 

[dans03firebolt]

i use amsoil 20w-50 in my primary and 75w-90 sevear gear on my clutch side.

Can you tell me how you do this? You can only put one kind of oil in the primary area so you can't have 2. The clutch is built into the primary as is the tranny and it only holds 1 quart of oil. So please let us know how you are putting oil in 2 different places. The bike only has 2 kinds of oil. Primary oil that pumps the tranny and clutch and then the 20w50 that goes in the swing arm for the engine.

 

[mrdozer2you]

Can you tell me how you do this?

The oils are seperate, one for the engine, one for the clutch. There are 2 drain bolts. The one under the swingarm and one near the front left side of the engine.

 

[Roccodart440]

I think the clutch is actually smoother now with the amsoil

I know this but if you read his post "i use amsoil 20w-50 in my primary and 75w-90 sevear gear on my clutch side. " It states he is putting 20w50 and 75w90 in his primary. That can't happen do you see what I am saying? I know there are 2 drain plugs one for the primary one for the oil reservoir in the swingarm but you shouldn't be running 75w in your primary.

 

[FIDOSOL]

clutch side, would be in reference to where the other drain plug is I imagine...

 

[06xb9r]

I think he is calling the crankcase oil (swingarm) the primary oil

 

[dans03firebolt]

If he is then he is not doing things right. You shouldn't run 75w in your primary.
