Re: How important is this Bolt?
That is the left front engine mount bolt, there is one just like it on the right side. Those two bolts are what suspends the front of the engine from the frame, so they are extremely important. However, nothing can happen if the bolt does not come out, as it is in a rubber bushing in the engine support mount, the engine hangs from the frame.
If you make sure the right bolt tightens, the engine cannot move left/right, and if you can insure the bolt cannot work out the bike should be safe to ride.
It would be a pretty good job to replace the left engine support, but that is what should be done if the threads in it are stripped.
I do not remember whether the bolt screws into the bushing or the support bracket.
The bushing is part number 46 51 2 332 110
The support bracket is 46 51 2 332 863
