High performance Keihin PWK / OKO

Main high jet valid for PWK type carburetors, from manufacturers Keihin, Oko, Koso, Stage 6 R/T, Vicma, Voca...

If you need to adjust your motorcycle's carburetor, the high jet is one of the elements you should not overlook. To select the appropriate high jet, we should start with a larger one to avoid damage caused by a lean mixture. After driving at full speed on a straight road, we should check that the spark plug shows a "café con leche" (coffee with milk) color with a dry electrode. If it shows signs of overheating, it means we are using a jet size that is too small. Conversely, if it is wet, we are using a jet that is too large.

Sold individually, available in various sizes, choose the one you need.
