2 bolts. 13mm

13mm what does that tell those of us who have been working on Yamahas? Tells me a lot!

 

[snowbeast]

I was sold on them with Husqvarna XP chainsaw mufflers falling off. This or spotwelding was only thing that worked. Later Cannondales which had a "issue"! You can get them at McMaster Carr or a lot of Hardware places like Fastenal.

Ya,whats up with 13 mm stuff anyways,when we were setting my sled up for the drags,every bolt seemed to be 13mm or 11mm,the slider lock bolt nut is 11mm and hard place to get a wrench into,i had to grind down a 7/16th wrench to applicate it.
