I had an idea.... I run that Tudors no-blow copper head gasket in my bike.
Its flat metal, just like the head/cylinder. Because of this, you need to use a gasket maker around the
studs, and basically the entire surface on the top of the jug, and on top of the gasket (for the head) in order
for it to seal like a head gasket should. It doesnt fill in the imperfections in the metal like a real gasket does because its hard metal.
(hence the use of the gasket maker)


My idea: If I can use that gasket maker and make the copper "gasket" seal, why run that gasket at all?
No gasket would increase compression drastically and would require the use of race gas, but it seems to me like it would
work as long as you used that gasket maker on the entire surface, and around the studs. (just like I am now!)

What do you guys think? I know its kind of stupid, but its really no different than using the copper gasket because the copper is hard metal just like the head/jug. (it doesnt really work as a real "GASKET")

CRAP i just realized that I posted this in the Yamaha forum, oops

 

Dont worry about it, Your getting a banshee! banshees will use the head gasket LOL!

RoostKing...

 

Running a thicker gasket or a thinner gasket will alter your head volume. By running no gasket you are decreasing head volume hense more compression. Head gasket widths are very important. Thats the main reason why people run the CR head gasket on the 250r's is because it creates more compression, its the same concept, except your taking it to the extreme

 

Well my Zilla is listed, but I still have it... so it will be my on-going project untill it is sold.
I still love this bike. Its a torque monster, and thats what makes it so much fun in the dunes.
But theres always room for improvement.... and ill continue to ride it (When I can) and play with it untill it sells.

DaBeechMan, I know how that works. Im just asking why it WOULDNT work. (what I said in my post)
If im making metal on metal, on metal work with gasket maker, why wouldnt metal on metal work the same way?

? do it and let me know. Then ill tell you why it would or wouldnt work [img]i/expressions/face-icon-small-smile.gif[/img] This is just me, but id hate to blow water out of my head and get stuck out of the middle of nowhere, or have it spit water during a pass and seize the motor. But...we live and learn somehow right.

 

when im not so liquored up ill give you a straighter answer...

 

HAHA ok Beechman, go sober up will ya[img]i/expressions/face-icon-small-wink.gif[/img]

 

Look at the mid-80's KTM dirtbikes. THey used a paper head gasket. It was no thicker than notebook paper. The cylinder and head were so well machined, that that was all they needed. I guess you need a little something that can be torqued down though.

 

It all depends if your cylinder has been decked and how thick of a base gasket you are running. It does not work I have tried it and it messed up my head. The piston hit the head. There is a fine line on how thick or THIN you can run them. Just thought you might like that info.
