Build Your Own 36mm SmartCarb Twin Kit

All-new Twin 36mm SC3 model SmartCarbs come in a right-hand (RH) and left-hand (LH) set and are designed to replace conventional, top-pull/single-cable throttled, spigot mounted carburetors of similar size in twin-cylinder applications, offering unbeatable performance and incredible ease of use. They are a direct fit in applications originally equipped with Keihin PE, PJ, PWK and Mikuni VM and TM series carburetors of similar size. In general we recommend replacing size-for-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. SmartCarb Fuel Systems makes no guarantees regarding the suitability of this product for use in unknown applications or in those for which it was not specifically designed for. 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 per carburetor to your order relative to the metering rods 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 application 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 (if applicable).

Fitment Information

36mm SC3 model SmartCarbs accept any throttle cables designed for use with Keihin PE, PJ, PWK and Mikuni VM and 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. Standard throttle cable guides are included with your purchase. A variety of angled throttle cable guides are available to order here.

View the 36-40mm SC3 SmartCarb Dimensional Guide to assess fitment potential. A, B, C, D, and body width dimensions included below:

A (engine-side spigot outer diameter) 46mm
B (length end-to-end) 80.5mm OR 90.5mm – 97.5mm using the SmartCarb Extension Ring Adapter
C (total height, including clicker adjuster) 172mm
D (filter-side spigot outer diameter) 62.4mm
Body width – 74.5mm

NEW: Purchase 3D printed solid models or Download the 3D print-ready .STL files below for mocking up fitment.

36mm SC3 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.

A minimum distance between intake centerlines of 80mm is required for mounting Twin 36mm SC3 SmartCarbs.

SmartCarbs 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.
