Couple of questions

[cass38a]

After you have run your bike in you can use synthetic oil (I have for a year) the synthetic oil will not make your clutch slip. If the oil has friction modifiers in it (like car oil) then your clutch will slip. Just go to Supa Cheap and get some 10w40 motorbike oil (I got 5 liters of sikoline there a few months back).

Its better to keep your mouth shut and have people think that your a fool than to open it and remove all doubt.

the reccomended oil is 10w 40.

To my knowledge the W (weight) value, is the oil's velocity when it is at -25 degrees celcius. The number infront of the value determines the thickness. The lower the number the thiner it is.

The 10W should be used because these engines have narrow oil passages, and you don't want to use a heavy weight oil as it can struggle to get around and can't lubricate the needed spots. (This occurs on cold startup where most damage is done)

The seccond value is the velocity at 100 degrees celcius.

Goose, these engines do run oil pumps.

Technically an oil slinger doesnt pump anu oil ,it just sprays it around by "slinging"it

Yeah, it's not the oil slinger i'm talking about. There's a oil pump aswell. it runs off a gear off of the crank.

alritey just to let u know the oil that comes in ur bike is called "transport oil"
this isnt even oil its a solution to stop the insides of ur engine from rusting while sitting in the warehouse
as soon as ur engine is started this stuff goes like foam

Just to clarify the weight values a bit
In a multigrade oil rated 10-40W
10w is the viscosity rating when the oil is cold
40w is the viscosity rating of a 40w oil when hot (operating temp)

I would deffinatly stick to 40w, or 50w if you have to. Car oils are generally not a good idea to use in motorcycles. Motorcycles have a wet clutch which can be affected by the additives in car oil, which can make the clutch slip. These additives are usually stated as "friction modifiers" on the label.
Its best to stick to motorcycle oils, or oils that are labelled as diesel compatible as these dont normally have friction modifiers. I use Fuchs titan which you can get at bursons

I will stand corrcted if thats true,i was going off info that id come across on this forum but if its wrong,hey i'll eat my words..

yer i dident even know they made 20-60 oil fore dirt bikes i thort that stuff was fore cars i run the 10-40 or 15-40 mabe somethink a little thiker in this 40+ degree heet but wouldent go to thick!

I have changed the oil a couple of times in my china.... and never changed a oil filter... do they even have on? lol
btw, im using 20w50 synthetic... but its the same oil I put in my R1 so i guess its good heh
