Frequently Asked Questions
What OE number does this replace?
This is a direct replacement for OE# 34906-85A on Evo Big Twin engines.
Why buy a 5-pack instead of singles?
The 5-pack is ideal for shops, fleets, or riders who service multiple bikes or want spares on hand for future rebuilds.

Good gasket, I like these because they are the same thickness as factory, and do not change the end play on the cam and breather

Decent gasket. Sticks out of the nosecone cover a bit at the top as it doesn't follow the nose cone shape precisely. Seals well.
