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
