ESP Modified Zenoah "G340RC" 34.02cc 4-Bolt Engine - Complete with Clutch
This is a Zenoah G320RC 31.8cc engine that has been ESP Modified with a DDM +2mm stroker Crank and Cylinder Modification to accommodate the longer stroke, resulting in a 34.02cc "Factory-Style" engine.
The Zenoah Factory G320RC engine is an all new design - redesigned cylinder, crankcase, crankshaft, piston, etc for an absolute explosion of power, yet still in the same size package as the original Zenoah RC engines (G230/240/260/270/290RC)) This Zenoah G320RC engine has a 38mm bore, and 28mm stroke, for 31.8cc in its stock form.
This ESP Modified version has a 38mm bore and 30mm stroke for 34.02cc. Includes a revolutionary new cylinder design with closed deck transfer ports (two piece), with removable covers. The release of this Zenoah G320RC engine is the biggest news to hit the R/C engine world in years! We have been testing this engine for the last few months, and the power output is incredible. This ESP Modified version adds even more torque.

This engine's outer clutch housing is available in 2 versions. When ordering, select the clutch housing option you need from the drop-down menu.
BB128C - This is the factory version of the motor - comes exactly as manufactured by the Zenoah factory, with no modifications. Fits HPI Baja 5B/5T/5SC, Kraken Vekta.5, Helicopter, etc. This is the version that will work properly for most applications.
This is also the version that would work with the Losi 5IVE-T 2.0 and DBXL 2.0 models when paired with the Losi LOS252093 clutch housing. The 2.0 Losi models do not require a CY fan cover or clutch mounting plate.
BB128D - This version of the engine has a modified "shorty" clutch housing - For R/C cars that were originally designed specifically for CY engines, which have less total engine width. Fits Losi 5IVE-T 1.0 models, TLR 5IVE-B, Losi Desert Buggy XL (DBXL) 1.0, and Redcat. A CY fan cover must also be used for this engine to fit a Losi 5ive, TLR 5IVE-B, Losi DBXL or Redcat. This is the stock fan cover from your Losi 5IVE, Losi DBXL or Redcat. We also have these fan covers available for purchase separately (see item EG411), also at the bottom of this page in the "related items".
MOST Losi clutch bell set ups also require you to use the CY Clutch plate (see item GT244) and clutch plate bolt (GT249) as the Zenoah mounting plate pushes the clutch shoes too far out. This includes stock Losi/TLR clutch bells.
Note: Aftermarket Billet aluminum clutch housings are available for the HPI Baja 5B/5T/5SC, Goped, Kraken Vekta (see part number GT396) and Losi 5ive/DBXL & Redcat. (see part number SM106SV, SM110). If you plan on using one of these for a Losi 5ive or Losi DBXL, purchase the BB125C and save yourself $5, as you won't be using the stock clutch housing anyway.
Here is a YouTube video that helps explain the clutch options:

Here is a YouTube video that helps explain the clutch options:
This engine is not compatible with most FG Modellsport or Smartech models. The larger crankcase interferes with the input shaft into the transmission.
Fits most all the same applications as the regular Zenoah R/C Engines: HPI Baja 5B/5T/5SC, Losi 5ive, Losi Desert Buggy XL (DBXL), Redcat, Go-Ped(clutch driven versions only), Helicopter, and more! For Go-Ped use - This engine will bolt on and work on existing 54mm clutch models. Will work on spindle drive models only if ADA clutch is used (part gt201). This is a complete engine - including carburetor, air filter, clutch, and muffler. The exhaust port spacing is the same as the original engines, so all exhausts, tuned pipes, etc will remain compatible. The cylinder includes removable transfer port cover plates, these plates can easily be removed for easier access to the transfer ports.

Details
Fits most all the same applications as the regular Zenoah R/C Engines:
HPI Baja 5B/5T/5SC, Losi 5IVE-T, TLR 5IVE-B, Kraken VEKTA, Losi Desert Buggy XL (DBXL)/MTXL, Redcat, Go-Ped Scooters (clutch driven versions only), Helicopters, and more!
For Go-Ped use - This engine will bolt on and work on existing 54mm clutch models. Will work on spindle drive models only if ADA clutch is used (part GT201).
This is a complete engine - including carburetor, air filter, clutch, and muffler. In many applications including in most RC cars you will remove the factory Zenoah exhaust muffler and air filter to use the exhaust and air filter that came with your model. The factory Zenoah air filters are not made for extremely dirty or dusty environments.
If you need a replacement modified cylinder set for this engine that listing is here: ESP Modified cylinder kit for +2mm stroke crankshaft
With the modified cylinder, crankcase and long stroke crankshaft you can increase power output with a few options:
Upgraded transfer port covers. These can be used with the factory Zenoah cylinder as well as any ported or modified cylinders. Bartolone Racing and Turtle Racing/OBR offer some that can be seen here: Bartolone Covers and TR/OBR Covers
The ESP Ported AND modified cylinder (for use with the +2mm stroker crankshaft found in this engine) will increase peak RPM and HP from the original modified cylinder: ESP Race Ported and modified cylinder kit
