Product Details

The Mikuni N102.221-70 is a precision-manufactured main jet designed for fine-tuning fuel delivery in high-performance carburetors. This #70 jet features Mikuni's small round design, engineered to provide accurate fuel metering for optimal engine performance and throttle response.

Key Features:

  • Jet size: #70 orifice for precise fuel flow control
  • Small round main jet configuration
  • Direct replacement for stock Mikuni jets
  • Precision-machined brass construction for durability
  • Compatible with SBN 38, SBN 44, and SBN 46 carburetors

Main jets are critical components in carburetor tuning, controlling the fuel flow at mid to wide-open throttle positions. The #70 designation indicates the orifice size, allowing tuners to dial in the perfect air-fuel mixture for their specific engine setup, altitude, and performance requirements. Proper jetting ensures maximum power output while preventing lean or rich running conditions.

Perfect!

Please I need the piece asap

The ordering process has been quick and easy.

good

Shipping is too expensive.

Made a hard to find part easy.When I received the part it looked like a return from the tape job on the box. Part looked new but handled in an attempted install way of appearance. I'm sure it'll be fine.

so far so good

Great price, free shipping and offered Amazon payments!!

Found what I needed at a price that was better than any other I found in my online search. Ordering was easy. I will definitely access your website for products as I continue with my car build process.

This was my first order with Autoplicity. I was pleasantly surprised when my order showed up quickly and was exactly what I wanted. I will be buying from this company again. Thanks for the quick service and fair pricing.
