I always get a chain with 120 links or more. Link counts that are suggested for your model and year are based on stock gearing. If you have deviated from stock sprockets, you will want some extra links with the new chain, so you don't wind up using any old chain. Of course I always have to break the chain, but I get the axle where I want in the adjustment range. A chain breaker tool is great to have in the trusty tool collection, but the chain can be broken to the correct length with a grinder or heavy duty belt sander and a punch. You just have to be a little more careful that you don't damage the new chain when you break out the BFH.
