i no this probely is the most stupid question anyone has prob ever heard but what gear oil do i use for my DT 125R

cheers

Hi, You dont want anything too thick, Or it will clunk like mad when you put it in gear, especially when cold. 20w 40 should be ok.

If 2 stroke (and I think it is), then either EP-80 or EP-90 grade, depending on where you live (one is slightly lower temp than the other).

(20W50 etc for 4 stroke engines)

(Not a stupid question)

I use this http://www.lgracing.co.uk/productdetails.php?productid=1517

Works great for me been through 3 or 4 oil changes now really feel the smoothness in changing gear when new so nice
