Skid Plate Install Question

[LuvMyWarrior]

Hi Guys,

I am at work so I cant check myself. Does anyone know if an Attak GT has pre drilled holes on the belly pan for a Skid Plate? I ordered one and want to get it installed - just dont know if I need to drill any holes - hopefully Yamaha did this for me.

Thanks!

4 holes to drill

You will have to drill 4 holes. The locations of the four holes currently have rivets installed that you'll have to drill out first. Then you use a 25/64" bit to make the holes the correct size for the inserts. Using the supplied insert tool is a pain... I borrowed an air insert gun to do it. Good luck!

Also, if you haven't checked this out already, do a search for "skid plate rivnut install" and among other things you will find a suggestion to use inserts with the body length being 17.27 mm long. The inserts that came with the kit in the past, are 14.73 long(not including the head) and are in many opinions, not long enough.

I've found many people don't understand how they go in. Drill the hole, press in the rivnut (tap flush), insert the threaded installation tool, tighten the nut (on the threaded bolt installation tool) until it is very hard to turn (this flares the rivnut against the thin aluminum tightly), then remove the bolt, and screw in your regular screw. Just like a hollow wall anchor, but they must be tightened so the inside portion flares and squeezes the metal. Most don't go far enough with this part making them loose, or not flared and they fall out.

I also got a bunch of good ole 'murican threaded ones from Fastenal.

It is true that the rivnut inserts are designed to expand filling the hole, but equally important and what keeps them from falling out is, that they form a backside flange on the metal they are installed in. So, if they are not long enough, they simply will not work.

Yep great thread you did there. Look in the FAQ section, I put a link to your thread, you will see it at or near the top.
