xr650r Spark Plug Wrench

[PigRider]

I seem to have "misplaced" my old spark plug wrench that I used for the xr650r. A standard plug wrench is not thin enough to get the plug out (the cylinder gets in the way), and the hardware stores carry wrenches that are too long to reach the plug without loosening the tank. Anyone know of a source for a wrench that will work? The simpler and cheaper the better.

I use a standard spark plug socket and put a box end on the head of the socket to turn the socket
