Stupid header donut

Anyone notice how annoying it is when the donut gasket on the rear header disintegrates? I knew my hawk was getting louder and eventually it became motogp loud. I repacked the mufflers but then realized the donut was also gone.

The hardest part is getting the inner stud nut off the stud, but then also the clamp bolt head broke off and its impossible (so far) to get that clamp off. I will probly have to cut it with a dremel if I can reach it.

Weird how all this happened and the headlight bulb blew all on Thanksgiving.

I am thankful to have a bike to wrench on.

I've replaced all the exhaust gaskets about three times now... and its not like im taking the headers and cans on an off monthly so "wearing" them out.
But after a year or so Thats all year round riding like you, Texas Hot to Texas cold (high 20ths at worst and more commonly mid 30s for a few weeks)
So yes, I too have found the gaskets dont last.

That's sort of good news. At least I am not alone in the struggle. Gotta say the can repacks are about the same interval. Even tried different brands of packing, ceramic, etc. They all disintegrate about the same.

My bike also begun this back in September. I had to tighten the header to remove the space from the lose of the doughnut. And this after only 6000 km of riding after putting a new one in.

My thought is to put 2 instead of 1. This will also take care of the little loose in the rear header that was there even after having put a new one in last Spring. Perhaps there are other solutions to this problem, like the use of another gasket from an other brand.

Any ideas are welcome...

So Jack for me the issue was the donut or whatever Honda calls the gasket that goes on the other end of the header, not at the cylinder. The one that connects to the exhaust. Its a thick fiber donut that must absorb a lot of vibes and jarring from bumps, thus pummeling it.

I always keep several on hand for this issue. I have always used them.

Personally on my Hawk i have never had an issue with the gaskets

But where i work we have a long time customer with a XL Varadero and like you guys i have replaced that one gasket on the rear header 3 times

And a Varadero is a bitch to work on alot more needs to come off before you can get to the exhaust

Maniac, how many miles (or kilometers in your case) does your bike have? They just wear out over time and really bad roads make it accelerate. Keep an eye on them.

I don't have one, just liberal amounts of high temp silicone gasket goo.

No leaks at this stage but link pipe not standard either and a very snug fit.

Hahaha nee klopt, die Varadero heeft meer op de teller staan

(That varadero has more miles on it but also more weight)
