Specification index

Every number Snowbum states, pulled out of the prose and gathered in one place, each one linked back to the sentence that qualifies it.

This index is a finding aid, not a specification sheet. Values here are stripped of the conditions that govern them — model year, whether threads are oiled, which of two supersessions you have. Never torque a fastener or set a clearance from this page. Open the article and read the sentence.
