A burnt valve will cause the cylinder to either be week or misfire completely. Depending on how much compression is present. Sometimes after reaching
crusing speed it feels as tho the cylinder is pulling it's weight, this is not true.
The only way to correct this is to pull the head and do a valve job. I would
reccomend doing both heads at the same time if applicable.
