Missing bolt?

[swampfoxsc]

There seems to be a missing bolt on the right side of the cylinder head on my 450R. There is a threaded hole but I can't find a picture that clearly shows a view of this area. It's not on any parts schematics either. It's located on the right side in the center of the head right behind where the exhaust attaches to the head.

Can someone check and see if their 450 has a bolt or some other fastener in that location? I don't want to ride it until I know and I want to ride real bad so please hurry! LOL!:D

Mine is the same way.

It's a drain hole for the spark plug tube that runs through the head. It just allows water to exit from around the spark plug.

No bolts or plugs go in it.
