sprocket question

RE: sprocket question
On a 530 chain the '5' designates 5/8" between pins and the '3' is 3/8" sprocket width. The 520 is again 5/8" between pins but 2/8" or 1/4" wide sprockets. So you eliminate mass from the chain and sprockets and that is a good thing. Bad part is you have less sprocket and chain contact area so the parts will wear faster.
