rincon 680 oil drain plug.
Thank you all for your info & advice. I did the oil change today and it seemed to go well. I only got the Rincon a couple of months ago, and decided to change to synthetic oil. I have never done this before because this is my first ever ATV!! I wanted to do it myself, but not cock things up, so I asked you for advice. I did find it difficult to use a socket wrench for the drain bolt because I couldn't get the wrench on the socket once the socket was on the bolt head. There just wasn't enough room because of the skid plate, so I used a regular wrench, as I didn't want to remove the plate.
Anyway, I manged to do the job, and can't see any leaks!
I used Mobil1-4T racing, and it took around 3.5 quarts. I'll take it for a run when the rain stops, and check it out.
PS. Honda Tinkerer, What do you mean by the washer sliding down the bolt??
