How do you adjust the camchain on a honda vt250 1983?

Question

Or is it automatic ?

Answer 1

On the rear of each cylinder is a flanged (built in washer as part of the bolt) bolt with an additional washer.
Sitting on the bike, they're on the left side of the "rear" of each cylinder.
While the engine is idling, loosen the bolt.
After a few seconds, when the noise quiets down, tighten the bolt.
Then do the other cylinder.
