Exhaust Manifold Nuts

[Jvheli]

So I just picked up a new 2018 Rocket and have already lost an Exhaust manifold nut with less than 300 miles on it. I checked the other manifold nuts and there were loose as well. Can someone with a service manual tell me when these should be torqued to? Should I just remove them all and loctite them?

Any advice would be appreciated.

Locktite might work, but they loosen as the copper gasket seats and they come loose. Ive found a couple of retorques and the stay put just fine.

Ive put lots of exhaust systems on various bikes and it holds true for all of them.

Does anyone know where to get replacement radiator shroud bolts, I guess they need to be checked often. It looks like its about 3/4 inch long, large button head.

As I've worked on my motorcycle (all of them, in fact) I find missing bolts -- a product apparently of widespread practices in the consumer repair business, "If the customer can't see this, the fastener is optional."

On the Rocket specifically, I like for all the fasteners to be present the manufacturer thought important enough to include in the costed configuration, and found all available from Hermy's in Port Clinton, PA.

I have went with titanium exhaust manifold nuts.
They remain tight much better.

I’m not putting JB weld on my nuts!

A GOOD AMOUNT OF JB WELD AND WAIT FOR IT TO GET HARD (permanant) sorry caps

I use copper anti-sieze on mine when I remounted my header and just torqued them down. Haven't come loose on me yet, but I didn't want to deal with the gunk of threadlock or seizing of dry bolts.

Ti nuts are great, light, and strong. And those colors are some cool bling on the engine. They can be brittle if not fabricated properly. However, the biggest issue with them is cold-weld. They will seize, so another good place to use the copper anti-seize.

I hope you know those are titanium alloyed not full titanium. Titanium is added to refine grain structure. Smaller interlocking grains stronger and tougher metal.
