It's possible. In that case it could also be another air leak somewhere, sticky throttle, or bad jetting. Don't let your friend keep riding it like that because it will eventually seize up.

The seal could be bad, but for sure your friend is leaning out as he warms up (normal) which is causing a lean condition (not normal). Seal leak, jetting, etc. Gonna need to figure out why before it's toast.
