Valve guide (exhaust)
An exhaust valve guide from the cylinder head assembly, also listed under the older E12226 number.
71-2226 is an exhaust valve guide as listed in the cylinder head and barrel section of the parts book. It sits pressed into the head where the exhaust valve stem rides, and its job is to keep that valve tracking straight as it opens and closes thousands of times a minute, carrying heat away from the stem in the process.

This one shows up under the legacy alias E12226 in older parts books, same physical guide, just the pre-73 numbering style. Our catalog record for it is thin - just the one listing tied to 1971 - so we can't point you to a specific model off what we have here.
If you're replacing exhaust guides, it's worth checking the guide bore and the valve stem together rather than just swapping in a new part on faith. Give us a call with your head off the bike or your model details in hand and we'll help make sure this is the right one before you order.
