The design of the KOSO flat slider carburettors is based on the KEIHIN PWK series and includes many of the advantages of the original. They stand out thanks to their compact design, are fitted with a chrome slider and a CNC milled intake duct. Thanks to the power jet, the engine can be tuned more leanly in the middle rev range without making it excessively lean at full load.

We stock the KOSO 28-39mm carburettors for the 39mm engine connection. We can also offer the specially revised KOSO 28-32 in the current 36mm connection width.

A connection rubber and a corresponding clamp are included. To adjust the carburettor optimally to the engine and purpose, working with a complete jetting kit is recommended, however.

Conclusion: Unbeatable price-performance ratio and therefore a genuine alternative to MIKUNI and co.

SIP-TIP: Order a suitable air filter (e.g. part no 40338000) at the same time. Jetting kits (e.g. main jet part no KODB0010 and idle jet part no KODC0010) make the tuning easier.
