I have decided to extend my swing arm 6 inches, and was wondering a few things about the chain. I feel completely comfortable changing the swing arm, but the chain worries me a little. I have done some research, and it seems that the best grade to go with my stock bike is the 530. The length is a little confusing, but from the mathematics I would need a 132 link chain, only problem with that is the chains are sold in 130, 140, and 150. Would I just need to grind the rivet off of a link, and then press it out? Also the chain is a rivet style, but I have never worked with a rivet style chain. I have reviewed the photo's provided by pashnit, but the pictures are very clear about what the chain looks like during the master chain link process. Does any one have a few photos of what the link looks like before being riveted, and what a properly finished rivet would like? I know the idea is a little silly, but the fact is that I performed the chain installation improperly really........ really ...... bad things would happen.
