Title: What is oil leaking out from?
Post by: kneeslider on March 26, 2016, 10:02:42 AM: Hello.

Just noticed my DT200 is leaking out some engine oil.

Here is the pic, so what is leaking out off? Easy fix?

I saw it has an o-ring . Since it would be a big story to source one, I just used gasket maker.
I did it at night, so next day it was ready to ride.
Easy peasy !

That big screw cover is access to the 19 mm bolt on the end of the crank that holds the alternator rotor. Oil vapors and droplets will gush out this hole if open while engine runs so don't do that! The only reason to take that cover off is to turn the engine to adjust valves.

Karl could you use that nut to hold the crank when you torque the variator nut, I could not find torque value for the crank nut, should be the same or higher for it, that would be for people who does not have a holder for the variator,.

Not a clue here on this bike.....but I'm thinking that the torque required for the clutch and variator nuts is pretty large and would not want to put even some of that stress by holding something, somewhere else. I'd wait and get the holding tool ($12 eBay, or make one ??).
