Once I can see, twice... ok. But between all the posts and forums I've seen this mistake almost a dozen times now.

There are two bolts on the bottom of our engines, ONE is the oil drain plug, the other is the cam chain tensioner. The oil drain is a nickel plated 17mm, the cam chain tensioner is a chrome 14mm. Removing the cam chain tensioner bolt releases the spring that keeps tension on the cam chain (hence the clever name) and if the engine is turned over or started with this bolt/spring out it could cause serious damage.

For you graphical types:

Protip - a chunk of 2x4 under the kickstand will level the bike making the oil change much easier if you don't have a swing arm stand.

Why not just make the tensioner bolt tamper proof, a security Torx, or some other means so as not to remove it.

Sooner it later someone will remove that bolt and destroy their engine.

Just popped the drain plug for the first time after consulting the Maintenance manual and confirming by your photos.

Oil poured out as it was supposed to. Thanks for the heads up!! Emoticon Yellow Smiley Smile Icon

Just an FYI, With the kickstand already on a 2X4 to bring the bike upright, I grabbed the front brake and leaned the bike over to the right side after the oil stopped flowing and a good bit more came pouring out (~half a cup).

Dang!! Look what came out with my OEM oil (first change)!!

My first change was at 150 miles (today).

Owners/service manual FTW. Useful pics for those who don't like reading.
