I have a problem with galled threads on my lower bolt out of the three. Is this a bolt I can get at fastenal ? Or do I need to buy it direct from yamaha?

Also, is there a way to shine up the airbox?

That bolt is a special shouldered bolt available only from Yamaha.

Here's why the threads are galled: http://www.thumperta...ad.php?t=575367

Here's how to prevent it from happening anymore: http://www.thumperta...ad.php?t=634724

Also, if you find that the threads in the case need repair, be sure you use a Heli-Coil or Time-Sert that is long enough to completely close off the cross hole, or plug the hole as in the second link. Failure to see to this can result in a loss of oil pressure.
