Anyone running their bikes without one? Or what's the thinnest stuff available? The gasket material I've been using is too thick and robbing my kit of its better performance capabilities.
Here of people using aluminum foil and some stockers running no gasket at all.
Running a polini e50.
Ive made base gaskets out of binder paper and printer paper with good results
A lot of people have traditionally run two gaskets on 2-strokes to effectively raise the exhaust port w/o porting.
you can use a really thin peice of solder wire, bend it the shape of your flange... then crank her down... atleast thats what the pocket bike guys do to get around running a base gasket. but i hear you have to use really really super thin solder, like the stuff you use to solder on circuit boards with.
Would copper rtv work? It's an aluminum block on an aluminum cylinder.
Gonna experiment over the weekend with that and some other options.
copper rvt sould seal.
i run 2 sometime 3 base gaskets for better porting, i take it you looking for higher compression? its better to lose the head gasket than the base...

True that. mill your head so if you want to raise base gaskets for timing you can.
my doppler motobecane high comp uses a silicone o-ring so you don't need a head gasket.
You need some sort of a base gasket.
On many bikes running a thinner base gasket will increase compression but actually reduce overall performance by making your port timing less desirable. On some bikes you may actually want a thicker base gasket than they give you stock. Either way you need some sort of sealant or gasket, otherwise your asking for major air leaks.
I would much rather run a base gasket, so I'm gonna try and find something thinner than what I've been using. Pulled the cylinder last night and it's clear that the gasket never squished as tight as I thought. The carbon lip in the compression area has an extra millimeter at least in comparison to when I ran the polini base gasket. Definitely the source of my weaker compression I'd complained about close to a month ago. Ring seated perfectly with absolutely no signs of blow by.
