Build Your Own SmartCarb

This 28mm SC2 model SmartCarb is designed to replace conventional, spigot mounted carburetors in 65-300cc 2-stroke applications and in 100-250cc 4-stroke applications, offering unbeatable performance and incredible ease of use. It is a direct fit in applications originally equipped with Keihin PWK 28mm and Mikuni VM or TM series carburetors of similar size.

Choose this product only if you cannot find your application in the Selector Tool drop-downs on the Shop page but are confident in your ability and understanding to adapt it to your particular application or if directed to by a SmartCarb Fuel Systems technician or representative. Please review the fitment requirements detailed in the Fitment Information tab below.

The +2 Metering Rods option is recommended for unique applications and adds a one step richer metering rod and a one step leaner metering rod to your order relative to the metering rod selected and installed by the technician prior to shipping based on the application information provided. A technician may reach out for further information prior to shipping.

Every SmartCarb ships pre-adjusted specifically for the bike for which it is ordered. Please provide information in the forms below about any engine/exhaust modifications, how you ride (riding style), and what fuel selection and oil premix ratio you use. Specify which side you prefer the fuel fitting to be (standard, default location shown).

Fitment Information

The 28mm SC2 SmartCarb accepts any throttle cables designed for use with Keihin PWK 28mm and Mikuni VM or TM series carburetors of similar size, whether slip-end or thread-end. Slip-end cables may require moving the throttle cable guide from the stock carburetor to the SmartCarb cap (if possible). The SmartCarb cap or top cover uses industry standard M6x.75 metric threads for cable attachment. A standard throttle cable guide is included with your purchase. A variety of angled throttle cable guides are available to order here.

View the 28mm SC2 SmartCarb Dimensional Guide to assess fitment potential. A, B, C, D, and body width dimensions included below:

A (engine-side spigot outer diameter) 35mm
B (length end-to-end) 82.5mm
C (total height, including clicker adjuster) 144mm
D (filter-side spigot outer diameter) 50mm
28mm SC2 SmartCarb body width – 59mm

28mm SC2 SmartCarbs are spigot mounted and require installation and isolation within rubber manifolds. No hard contact or excessive vibration transfer are permitted. Hard contact between the carb body and the engine case, frame, or shock spring or excessive vibration during operation may cause fuel frothing/aeration resulting in potential engine damage or unsafe operation of the application.

The 28mm SC2 SmartCarb may be tilted up to 15 degrees either side for fitment clearance and up to 30 degrees forward or semi down-draft, but no further.

Rated 5 out of 5

Christian P. – November 2, 2022

Pull the trigger on 28mm Smartcarb for my Honda elite with a built 72cc polini corsa.After sending my build specs carb came in and the tuning was pretty close out the box. Throttle response is incredible smooth all the to full. My fuel mileage went up a ton. Bike runs cooler. I thought my PWK polini was a badass carb. But this Smartcarb blows it away. Well worth it.
