HS42/061-45 Alloy Manifold for Evolution Models (Rubber Flange not included)

Description

This manifold is for use on all Evolution engines with stock length cylinders and when fitted with the purchased here separately, either HS42/062-42 Rubber Flange for 42mm carbs or the HS42/062-45 for 45mm carbs will position the HSR so as not to protrude out any further than stock with the benefit of better carburetor heat isolation, more secure mounting and a 2 to 3 HP gain over the standard item.

On pre-1989 models still fitted with the rubber compliance fittings on each cylinder head, the purchase from your local accessories shop of OEM manifold to head o-ring gaskets and metal mounting plates will be required to complete this upgrade.

It is always recommended to replace your manifold to head o-ring gaskets when fitting a new manifold. Sorry not available through Mikunioz
