Very low-cost intake manifold for derestricting the inlet port. This increases the size of the opening to 21mm. This is a must when using a larger carburettor. Even when used with the original carb, acceleration is increased. A sensible purchase if your manifold shows signs of wear or becomes porous. Good simple intake for SR50 Carb conversions!
Fits Dellorto 17.5-21mm and Polini CP 17.5-21mm. Will fit most stock carbs.
New reed cage gaskets included
