So I had an interesting question I wanted to pose......
I have been working on cars for 35 years now. Every car I have touched with a a carburetor had a gasket between the intake manifold and the carburetor, and also one between the intake manifold and heads. The old carbed muscle cars also suffer from vacuum issues when leaks occur similar to the bike.
So that got me to thinking, why the o-ring on the intake boots instead of a high quality heavy gasket. I have made my own gaskets from the Fel-Pro thick gasket material more times then I can remember and it has held up even on the toughest of applications..... such as my supercharged big block with twin 4 bbl carbs and no vacuum leaks, and even high pressure coolant in a thermostat housing where if the gasket is not perfect, it will without a question fail and of course you all know what happens then.
What do you guys all think? Anyone know why motorcycle manufacturers went with an o-ring rather than a heavy duty gasket? The gasket material compresses when torqued down between two milled surfaces.
Was just curious as it does seem like gaskets would work wll there too but of course are limited lifespan as well and definitely wouldn't hold up to multiple removals and reinstalls like an o-ring might.
