The undersized are for builds that have had an align bore/hone on the mains. If your build hasn't then....?

I like my timing set on the tighter side as early run time usually loosens it up.

Mine was align bore/honed. My timing chain set hasn't loosened up in 4 years. I'm going to check my slack again this spring..and may swap my other set in.
