Description

Dial in your 2-stroke carburetor with confidence using the Naraku 5mm Main Jet Tuning Kit. Whether you're compensating for altitude, an aftermarket exhaust, or a performance air filter, having the right jet on hand makes all the difference. This 10-piece brass jet set covers a wide tuning range in a compact, organized storage case — so you can test, swap, and find your perfect fuel mixture without waiting on individual orders.

What's Included


  • 10 Brass Main Jets in the following sizes: 90, 92, 94, 96, 98, 100, 102, 105, 108, 110

  • Naraku Branded Storage Case with individual foam-lined slots to keep jets organized and protected

Features

  • M5x0.80 Thread: Fits Dellorto carburetors that use a standard M5 main jet — typically found on 19mm carbs and larger.
  • Wide Tuning Range: Sizes 90–110 cover lean-to-rich jetting for most 2-stroke performance tuning scenarios.
  • Precision Brass Construction: CNC-machined brass jets for accurate orifice sizing and consistent fuel delivery.
  • Compact Storage Case: Keeps all 10 jets organized, labeled, and ready for trackside or garage use.
  • Naraku Quality: Trusted European performance brand for 2-stroke scooter and moped tuning.
