Stopping spooge

[gwcrim]

One of my pals, an old school two stroke racer, saw my silver pipes with black spooge running down from the heads.  He commented that he used to take string and wrap it up inside the exhaust spigot to act as a gasket of sorts.

Anyone else try anything like this?  With success?

Clean gasket area, manifold and header prior to assembly.

Goop everything up with hi-temp RTV.  I usually use Permatex Ultra Copper.

Wipe of excess, and let cure overnight (at least) before running the bike.

Crisp jetting and timing helps too.

Viton Oring instead of the string works as well

If you decide to use string, use cooking string.  +1 on the permatex ultra copper.

I imagine silicone would stop the leak but wouldn't that make the pipes hard to remove?  Or reinstall?

I've had really good luck with self bonding high temp tape. It's kind of fiddly but holds up real well.

use 'the right stuff'. its expensove but works really, really well.

I used wood stove door gasket material, its heat resistant. I unraveled it to get the size of string needed to make a gasket.

I use the copper RTV and it comes right apart easily, but it's a pain to clean it all off and reapply every time..

I use a worm made out of steel wool drenched in high temp silicone.

Do the regular stock exhaust gaskets not seal well enough to prevent the dripping? Honest question.

[Dxrat]

This is where aftermarket pipes slip fit in to the header flange not the stock gasket location. They work pretty good.

I see. Gracias.

Mark beat me to it, but the right stuff is the the way to go
