Features:
- Complete carburetor Jet Kit: The package includes 6 main jet, 6 idle jet, 5 cleaning needles, and 5 cleaning brushes, all packaged in a small plastic box. Each jet is engraved with a number. The round main jet: #170, #175, #180, #185, #190, #195. The slow pilot jet: #38, #40, #42, #45, #48, #50.
- Function: The primary jet mainly controls the fuel flow in the main oil circuit and regulates the concentration of the mixture. The slow jet is mainly used to control the idle fuel supply and maintain stable combustion. When your motorcycle emits black smoke from the exhaust pipe, has high fuel consumption, carbon deposits on the spark plug, lacks power, overheats the engine, or backfires, it is possible that the high speed jet is blocked or damaged. When your motorcycle experiences unstable idle, easy stalling, difficult cold start, excessive mixture (emitting black smoke), and increased fuel consumption, it is possible that the low speed jet is blocked or damaged and needs to be replaced in a timely manner.
