I have a 1984 200 ES Big Red...Can any one tell me how to adj timing chain guides ?

If so thank you...

 

There is a cam tensioner on the side of your cylinder. I do not know how it works. I think you might just screw in the top screw on it. there are two bolts holdin it on to the cylinder and one in the middle. I would say turn the middle one see if it helps. But I think it would need changed and they are dirt cheap to buy... I would change your cam sproket too.
