could someone please tell me because i dont know were is the oil drain plug on the bottom of the engine i cant find it

 

If it's like my 250sx it's right in the middle of the skidplate under the engine. It looks like it's a bolt to hold the skidplate on but it's actually the drain.

 

On the 185 and 200 series the drain plug should be on the left side of the engine below the pull start
The drain plug and filter screen is same
I looked in manual the only other refrence was a 200X is different
Thanks
Ray
