Air filter low KY - A 140 D40

Low air filter, 40 mm connection; KY-A 140 series. The filter's job is to keep dust and sand out of the carburettor and cylinder: a clogged filter chokes the draw, and without one the piston and rings wear out fast.

• Connection diameter 40 mm — the rubber sleeve slips onto the carburettor spigot and is tightened with a clamp; the clamp is in the set
• The housing is low — fits where there is little room behind the carburettor
• The filtering element is a mesh: it can be washed and used again, and after washing and drying it is worth oiling with air filter oil (it is in the "Oils & care" category)
• When to change it: when the element stays grey even after washing, when it is torn, or when the rubber sleeve has gone hard and cracked
• The same filter is also made with 38 and 43 mm connections — you'll find them right next to this one, in the same list
• An open filter instead of the standard housing lets more air through: the mixture goes lean and the main jet usually has to be taken a size up — jets are in the "Carburettors and their parts" category

To be straight with you: the maker gives only the connection diameter — not the body dimensions, nor which engine the filter is for. The filter sleeve is measured on the inside and the carburettor spigot on the outside: measure the outside diameter of your spigot or send a photo — we will tell you whether it matches.
