S&S Cycle 84-99 BT 1-7/8in 410 Manifold Conversion Kit - 160-1658

S&S rigid mount manifolds are designed to improve intake tract air flow. These manifolds may change the way a stock carburetor and air cleaner assembly fit. This means that these components may require shimming and/ or a slight change in mounting bracketing.

S&S manifold conversion kits for Harley-Davidson® Evolution® are designed to fit stock displacement engines.

Series #16-1600 manifolds included in Manifold Conversion Kits are machined with a 17/8" throat and will fit stock Keihin® butterfly carburetors, all S&S 13⁄4" and 17/8" carbs, and any other carburetors with the same mounting bolt pattern.

S&S style o-rings must be used with these manifolds. S&S o-rings are slightly thinner to accommodate the larger S&S port diameter. Use of stock o-rings may damage the manifold.
