well i got a kx 80 today, havent got to ride it yet though since it has no chain on, i will be buying new chain and sprockets for it, maybe coil. there is a dent right at the header of the pipe blocking air flow about 1/3 to 1/2

what is all i need to know about these bikes? what should compression be at and what is the flappy thing in the exhaust port. its a 1993
