Stock suspension

quick question not even bout suspension but how much oil do I add back after I drain it mine has no looking glass so that's all I can think to do is make sure I put the perfect anount in

On side of clutch cover it tells you, 650ml. Be sure it is "Wet clutch compatible" or have no "Friction modifiers" I:I
 
alright thanks guys another oil related question i have had a post up before an i no a couple oils i can use for gear oil... but i was looking at my manule it says yamalube 10w 30 i belive inless i miss read it was a while ago... i can only find yamalube 10-w-40 witch is for 4 strokes its yamalube 4 thats not correct is it?
 
The oil specified is common garden 4 stroke engine oil, it is fine to run in wet clutch situations.

10W 40 will work but will cause clutch drag in lower temps!

Provided it contains no friction modifiers, any cheap 10w 30 four poke oil can be used in wet clutch boxes.

One can also buy specialised oil for motor cycle gearboxes with wet clutches, but it costs more.

Lots of guys here use Auto trans fluid type F in the gearbox.
 
blaaster i sent you a pm. and alright well i was looking at it an i didnt feel comfortable bying the 4 stroke for my two stroke im gonna look into atf type f my bike gets hot whats the best 2 stroke an gear oil to keep it cool?
 
What ^^Blaaster^^ says. I use ATF type F with absolutely no problems.. I like it because it's easier to keep an eye on when it gets dirty, although the fluid should be replace every few rides anyway.
 
I have always used Honda HP Trans Fluid , it is designed for wet clutches in 2 or 4 strokes , doesn't have the friction modifiers and is GTG in any temp , it looks a lot like ATF ( and probably is to a certain extent ) but has nothing that will harm the clutch friction plates .
