Compatibility Zenoah / Losi 5ive-T:Please note that for installation in a Losi 5ive the fan cover must be swapped for a Losi or CY cover #5341 in order to fit the chassis" bolt pattern.If you want to install a Zenoah engine into the Losi 5ive, you usually have to use a fan cover from the CY engine.However, there is a workaround to maintain Zenoah fan cover.The adjustment is done via the pinion specific mounting plates for the engine. The change always affects only the rear, outer (carburetor side) plate under the fan cover. This is rotated by 180°; so that the embossed number on this plate faces the exhaust side of the engine!18T pinion: use 20T plate, rotated 180°19T pinion: use 19T plate, rotated 180°20T pinion: use 18T plate, rotated 180°On the plus side you gain the opportunity to easily mount a Zenoah engine keeping the original fan cover. On the other hand there will be the disadvantage of the necessity to combine two different sets of engine mounting plates when installing any pinion other than the stock 19T version. Therefore we do not recommend this workaround for everyday use. Nevertheless it works perfectly should ever the need arise.Zenoah G320RC with Walbro WT 1107 carburetor (also available in the ball-raced version through the shop's options menu)With 32 cm³ and 30% more power than the Zenoah G290.Significantly more torque and higher stamina due to larger sized bearings all around, with Racing Carburetor Walbro WT 1107.The motor is supplied with WT-1107 carburetor and spark plug.SpecificationType: Two stroke gasoline engineDisplacement: 31,8 cm³Bore: 38 mmStroke: 28 mmWeight: 2,3 KgOverall Dimension:Length: 167 mmWidth: 215 mmHeight: 196 mmMaximum Output: 4,6 PSMaximum Torque: 2,00 N-mRotation Direction: CounterclockwiseCarburetor: Walbro WT-1107Spark plug: CMR7HStarting: Recoil starterFor all HPI Baja 5 cars the G320RCer clutch housing has to be shortened at the mounting base, for Losi 5ive- T and Desert Buggy XL cars the clutch housings overall length must be shortened to CY size.When installing the air filter you must pay attention to the length of the screws.For use on Losi and HPI we recommend M5x45 screws (like H94763); you can also cut existing screws to length, of course.When ordering with a modified clutch housing we will include these screws!In our shop you can select from Zenoah G320RC engines already modified to fit your HPI or Losi car.The installation of the Zenoah G320RC in other cars (like FG or Smartech buggies / monsters a.s.o.) is not even remotely straightforward, since the layshaft pinion (the small pinion in front of the big differential spur gear) is in the way for the larger Zenoah G320RC crankcase.Compatibility Zenoah / Losi 5ive-T:Please note that for installation in a Losi 5ive the fan cover must be swapped for a Losi or CY cover #5341 in order to fit the chassis" bolt pattern.If you want to install a Zenoah engine into the Losi 5ive, you usually have to use a fan cover from the CY engine.However, there is a workaround to maintain Zenoah fan cover.The adjustment is done via the pinion specific mounting plates for the engine.
