Securing the header pipe to the cylinder.
04/11/08 at 07:03:36
 
I am not convinced that my header pipe is sealed securely enough to the cylinder.  I have tightened it within my strength, but I'm not convinced the connection is sealed enough.  Is there a sealant or gasket or something that we can use to secure the header?  I'm not getting NEARLY as much crackling and popping as I was before I found the exhaust leak, but I'm a bit paranoid about the header pipe connection.

The gasket is a Crush gasket.   It's somewhere around $4 from the dealer.  

If you are " paranoid " replace it.

be careful on using your strength to tighten it. The Head is Aluminum and the bolt id steel... not a good combination. I found out that the last guy that worked on my bike had stripped the threads in the head. I coulnd't really replace the bolt with a bigger one, so I bored it out and put in some Heli-coils. Worked like a charm... just a little advice from someone elses mistakes. Replace the gasket!!!!

Most motorcycle problems are caused by the nut between the seat and the handlebars. Make sure yours isn't too tight or too loose.

A fifth grader with a sore arm could strip those threads, be careful getting rowdy there.

Replace the gasket & add a thin film of high temp sealant then just seat it snugly.  The sealant probably isn't necessary with a new gasket, but it will add to your peace of mind.  

I have to pull the front header from my vstar with every oil filter change.  I throw a thin film of sealant on each time just to get more life out of the gasket and hold it there while I'm trying to reassemble.
