OIL INDICATOR SPRING
Oil indicator spring for the oil pump and release valve assembly, also listed as E2788.
70-2788 is the oil indicator spring found in the oil pump and release valve assembly on the engine. It sits with the release valve and manifold, part of the oil pressure system that keeps the pump doing its job correctly. The catalog also lists this one under the older E2788 form, so if your parts book still uses the legacy prefix, know that it's the same physical spring.

Our records show this one turning up in the oil pump and release valve figure for 1964, and it's a single-appearance part in what we have on file, so there isn't a lot of extra detail to pass along. If you're rebuilding the oil pump or chasing a release valve issue, this spring is a small piece worth having on hand.
Give us a call if you want to confirm fitment before ordering, especially if your bike falls outside the year we have listed for it.
