Default Obviously I'm Stupid

Hi everyone,
I've only built up one bike and am always tinkering with it....so far it has NEVER failed me ....but....the kit I'm using is the Zoom Black 49 slant head.....and it did not include an intake manifold gasket which I didn't even know was supposed to be there....or is it ?....do most kits include one and if I'm not using one is it going to f#*k up my motor ?...I have almost 1000 miles on it so far.....I'd appreciate any feedback y'alls


Thanks!
Salty

I went to a automotive parts store and asked for gasket material for small motors. They showed me 3 rolls of different thickness's. I chose the middle one and it has worked fine. I made an exhaust gasket which is holding up well. I'd guess its about the thickness of a cereal box. The gasket that came with the motor lasted no time at all.

Thanks Mart!
I really appreciate your response......what I'm not understanding is....are these kits SUPPOSED to have an intake gasket ?.....bottom line is that's neither here nor there ....but if they ARE supposed to have one why wasn't mine ?......


Thanks,
Salty

these kits do include intake and exhaust gaskets,mine came with extra gaskets.
but they get old and you have to replace them and i just make my own out of a roll of gasket material.

Thanks Cabin........I reckon I'll go down to the auto parts store and see what will suffice.....the thing that perplexes me is....I've not had an issue with no intake gasket.....so I'm thinking that adding one will increase the performance.....is that right ?


Thanks again,
\ Salty

Mart....do you know if the same material will work as well on an INTAKE ?.......



Thanks, Salty

yeah, you shoulda got one with your kit. if your bike doesn't have an air leak, you're lucky. it won't mess up your engine if it's sealed, and you'd know it was leaking. it'd be revving high, or sputtering, or not even running at all.

just go to any auto parts store and ask them for the grey gasket maker stuff. they'll know what you mean, and give you a roll for a few bucks.
