Exhaust gasket melting

[Carlos motors]

Why is my exhaust gasket which I got with engine constantly melting?I destroyed 2 pairs of shoes because of that...

I doubt it is melting - more likely it is leaking - be sure muffler flange is flat and you might now need a new gasket if exhaust leaking has burned some of it away.

What mods have you done to your engine? What color is the spark plug?

Well I have installed new exhaust new air filter and new spark plug ngk br6hs I think and I have sanded head a litle bit . I am not sure if it is leaking because I always have little black liquid on outside of cylnder and it is coming from exhaust port.. And when I remove gasket I can see half of that rubber is missing. Also one question about head gasket I had 2 aluminuim with engine but my mechanic told me I need only one. My engine is curently out of work but I will check spark plug

And also do i need to jet my carb because i live on sea level litteraly my house is 30 meters from sea.

everyone needs to jet their carb.
only thing that matters is how much cranking pressure there is. Between 100 and 135psi is what you need. higher causes too much heat and stress on the bearings.

How can I measure it?
Do you think I need better spark plug?
And do I need 2 gaskets or should I make one by myself?

I mean 2 head gaskets.

you need a compression tester

Yes you can buy high heat gasket material and place it onto the head mating surface and with an exacto knife cut out the stud holes and then press along all the edges and remove it and use scissors to cut the internal and external outline. That will seal the head better than an aluminum gasket.
