Hi guys, I am new on here and was wondering if anyone knew how much oil I put in the crank case of a 1979 yz 125 2 stroke. Please any info would be appreciated.
You will probably find a level screw on the front of the clutch cover near the end of the crank (the only screw not on the edge of the cover) and after you put in your 650 cc or 0.65 of a litre you sit your bike upright and level and should get a few drips out the level hole. If none comes out you may need to add 50 ccand let the extra dribble out.
