The need for that bolt is open to debate. It provides the clamping force for the left front corner of the head cover. Suzuki must have thought it was a good idea to have it hold the head cover down, or they would have just made it like the other 3 bolts.
I gabbed these photos from the Technical Section. Here is a photo that shows the long bolt with the cover removed - and the threads do not run down far enough to allow it to be cut shot enough to put on a nut and have it tight.
And here is the gasket surfce that shows the bolt does provide a clamping force at the front left corner.
It is my opinion that the font left corner should be secured. If you are comfortable that it won't leak or warp with that bolt gone......that is OK with me......I just was not comfortable without having a bolt in that spot.
