Bisrollnaa Exhaust Gasket Installer Tool for Harley-Davidson — Black Anodized 6061 Aluminum, Fits Tapered & Flat Seals

If you service or upgrade Harley-Davidson exhausts, installing the gasket squarely in the cylinder head matters. This installer tool is machined from 6061 aluminum, anodized for durability, and designed to guide both tapered (H-D 65324-83B) and flat Screamin' Eagle (17048-98) style seals into the port without deformation. It removes the guesswork of hand-pressing gaskets and reduces rework from pinched or uneven seals.

How does this tool ensure an even gasket seat?

The Bisrollnaa installer centers the gasket as it enters the exhaust port so the sealing surface sits flush against the cylinder head. Its tapered profile and precise diameter match common Harley gasket dimensions to prevent folds and gaps.

• Machined to fit tapered and flat gasket profiles used by Harley-Davidson
• Guides the gasket concentrically into the port to avoid pinching
• Prevents compression distortion that can cause exhaust leaks

Which Harley models and gasket types is it compatible with?

This installer supports a broad span of Harley platforms and the most common OEM and performance gaskets. It fits Evo Big Twin and Twin Cam engines from 1984 onward and XL and air-cooled Buell models from 1986 onward.

• Tapered gasket H-D No. 65324-83B compatibility
• Flat Screamin'Eagle 17048-98 performance seal compatibility
• Suitable for Evo Big Twin, Twin Cam, XL, and air-cooled Buell applications

What materials and finish does the installer use for durability?

Constructed from high-grade 6061 aluminum, the tool is sand-blasted and finished with black anodizing to resist corrosion and wear. The surface finish minimizes friction while protecting the gasket during installation.

• 6061 aluminum for strength with lightweight handling
• Sand-blast texture to reduce surface glare and improve grip
• Black anodized coating for corrosion resistance and long service life

How does using the installer change the exhaust installation process?

Using the Bisrollnaa tool speeds up gasket placement and reduces the chance of redoing the job due to leaks or misaligned seals. It’s a simple addition to a mechanic’s toolkit that yields more consistent results than pressing gaskets by hand.

• Speeds initial gasket seating for faster assembly
• Reduces need for gasket replacement caused by damage during install
• Helps achieve even torque and proper sealing when torquing the exhaust flange

This tool is for motorcycle mechanics, DIY Harley owners, and performance shops that install or service exhaust systems regularly. If you work on 1984–present Evo Big Twin and Twin Cam engines or 1986–present XL and air-cooled Buell models and want repeatable, leak-free gasket installs, this installer reduces wasted time and parts. It’s particularly useful when fitting tapered H-D No. 65324-83B gaskets or flat Screamin' Eagle 17048-98 seals, and for anyone who prefers a durable, anodized aluminum tool made to withstand shop use.
