Frequently Asked Questions
Will this fit my Evo Big Twin?
Yes — this is a direct replacement for Harley OEM part #34906-85a used on Evo Big Twin engines.
Is this a one-time-use gasket?
Cometic gaskets are reusable if the mating surface is clean and undamaged, though OEM practice is to replace at each service.
What's included?
One gasket per pack — enough for a single inspection or derby cover installation.
Do I need sealant with this gasket?
Gaskets seal through compression only. A small dab of assembly lube on the bolt threads helps prevent seizing, but no RTV sealant is needed on the gasket faces.

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.
