So i am looking in thebook for the specsfor the properchain slack.The top of the chain lays flat on the guide and you can take the lower part of then chain and touch the frame. I don't think i can make up the slack.So what would a good brand of chain be?

 

Update: I found some writing on the chain. AFAM 5200S6. I take it that's a 520 type of chain right? Also i counted 45 teeth on the rear sprocked. That's not stock is it?

 

Not sure about that rear but contact this company and ask for Brian, he is great at geting you what you need. www.sprocketcenter.com
