Okay, I got the Primary Chain Inspection Cover off, checked the play of chain and it looks okay. Couple of questions:
1. They have note in the service manual - As chains stretch and wear, they run tighter at one spot than another. Always adjust the free play at the tighest spot in the chain. How do I determine the tighest spot?
2. To adjust the chain, the manual mentions loosening the top center nut a maximum of 2 turns, adjusting and tightening this nut back up. Now I can handle that. But can someone tell me what the Phillips head screw about 1 inch above the top center nut is? It is shown in manual but NO MENTION OR DESCRIPTION OF THIS SCREW ANYWHERE in the service manual. I just touched it with my finger and it's loose.
