About the Honda NRX1800EB Valkyrie Rune
Find the source of an oil leak before deciding which Rune gasket to replace.
Honda’s 2004 U.S. parts catalog identifies the NRX1800EB4 Rune with chrome wheels and a pullback handlebar. These details help distinguish it from the other Rune versions when checking a used or restored motorcycle. Confirm the model identification as well: wheels and handlebars can be changed after manufacture.
Oil can travel across an engine surface before it drips. Identify the highest fresh trace and the actual leaking joint before choosing a rear-case, breather-plate or clutch-cover gasket. The appearance of oil near a cover does not by itself prove that cover gasket has failed.
