Bolt (1 1/8 in. U.H.)
A 1 1/8 in. bolt used in the cylinder head and rocker box assembly on the top end.
This is a bolt used in the cylinder head and rocker box area, specifically length 1 1/8 in. under the head. It's one of several similar fasteners called out across the cylinder head and rocker box figures in the parts books, where these hold the top-end castings together.

Catalog appearances run from 1970 through 1974 across eight entries, which tells you it's a fastener that got specified more than once as the top end evolved through those years, but we don't have specific model-year fitment tied to this listing beyond that. If you're rebuilding a head or rocker box assembly and need to match original hardware, this is worth checking against what's actually on the bike before you order, since head bolts in this length range aren't all interchangeable position for position.
We don't have more detail on this one beyond the length and the general area it's used in. If you're not sure this is the exact bolt your rocker box or head needs, give us a call and we'll help confirm before you order.
