the link doesnt work the name of the oil is
15.5
15W50 - synthesis
specs
Semi-synthetic lubricant recommended for all motorcycle types.
Avantages :
-Viscosity of 15W50 grade gives very good stability over time.
15.5 offers excellent shear stability, and is ideal for traditional machines in regular use.

if you lost power it was probably the clutch slipping.

other opinions???

[YFZ450R-DEN.]

Yamaha recommend 5w50 max 10w50 oil and 100% synthesis

[Tilits]

do you think this oil hurt my bike?

[nickmell]

It shouldnt have hurt anything except maybe the clutches. Go get you some shell rottella 15w50 and change your oil. run it for a couple minutes and change it again. See if that helps.

thanks nickmell and YFZ450R-DE for your opinions. others opinions from other guys?

If you are changing the oil and want to use another brand, then make sure all the oil is out off the engine and maybe tillt it to left side so it all can run out, so you don´t mix to brands

thanks for this good advise.but the thing which concerns me if this oil hurt my bike . my mechanic put this oil 2-3 times and i visit the website of the oil and it says is ideal for traditional machines in regular use. and my machine is a racing bike and that is which concerns me. also another website says is good for racing bikes of 50cc

I believe the oil could have possible hurt the clutches, but without being there it's hard to say. If your not comfortable with tthe oil just change it I don't think you have anything to worry about especially if you changed the oil in question often.

I have not heard bad things about motorex, but it depends on the SAE numbers. (10w 50 or 15w 50) you know.
right now i see in the owners manual that it can run on: SAE: 5w 30, 10w 30, 10w 40, 15w 40, 20w 40 or 20w 50.
But I think it depends on where you are riding, you know the tempearature.
I´m from Denmark, and Yamaha said that I scould run on 5w 50 or 10w 50, because theres not so hot here like in Amerika. In the last days i have raced in -2 degrees;)

i am from cyprus ,winter is approximately 15 degrees and summer 35 degrees and i am thinking for 10/50 in the winter and 10/60 in the summer. what do you think?

[nickmell]

I have heard some bad things about the atv motorex oil. Do a search for rottela have never heard one bad thing about it and its cheap.

If you look on page 10-2 in the owners manual you can see wich oil you can run compareded to the temperature you are ridin in. according to that you schould run 15w 40 or 15w 50.

my opinion if i go with 15/40 i will lost some power because is thicker oil than 10/50.do you agrre?
the other thing i didnt found any good oil in cyprus which is 15/40 or 15/50

You will not lose power if you are running on a thicker oil.
When oil gets hot it will get thinner, so now i know that you are racing in hot temperature campared to me, so if you are running a thin oil you will lose lubricate effect, but when you run a regular thick oil maybe( 15w 50) you will result in a better lubricate effect because you are racing in hot temperature.

Remember when oil gets hot, it will fill more;)
