| 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!

Accessories / Spare parts
To ensure the required cooling for current 1/5 and 1/6 engines the flywheels have fins on both sides. Therefore the fan housing has large openings on the crankcase side for the required air supply. However, the risk of foreign objects (grass, sand, or even stones!) entering here Is very high! As a result, broken fins on the flywheel occur frequently. This leads to reduced cooling efficiency and - even more critical vibrations from a flywheel which is out of balance due to missing fins. Therefore, this kind of flywheel protection is highly recommended, especially for offroad use. The product video explains the handling in detail! Note:It is essential to thoroughly clean and degrease the crankcase prior to attaching the hook-and-loop tape (OKS2661)!For installation on Chung-Yang and Zenoah engines in FG cars, the crankcase cover must be slightly modified in two places where the engine mount is attached (see Figure 6 and 7). Furthermore the fit of the fabric must be as tight as possible in the region of the layshaft pinion (in front of the differential ring gear!) (see Figure 8).Set includes:Special tailored fabric with sewed on hook-and-loop tapehook-and-loop tape for installation to the crankcaseAdhesive for securing the hook-and-loop tape

Fully synthetic oil, available in three blends. 1-liter bottle.The optimal 2-stroke oil for 23-30 cm³ engines/cars Motul Racing Oil is available in three different blends: On-Road for high revving onroad cars Off-Road for cars with high torque enginesMixing ratio for 1/5 & 1/6 applications: We recommend a mix with about 4% oil, which means 200 cc of oil to 5 litres of gas (1:25 ratio). With one litre of Motul oil you can mix about 25 litres of optimal fuel for your 1/5 or 1/6 car. That's enough for well over 20 hours of driving fun!

Now with the "K&N" version the engine mount has been changed to eliminate this discrepancy. However, all aluminum engine mounts available on the market share their dimensions with the previous plastic engine mount. For the installation of a G320 Zenoah in a "K&N" -DBXL two possible combinations exist in order to obtain the correct hole pattern:When using the standard (new) plastic engine mount a shortened clutch housing is required as in a 5ive-TWhen using an aluminum engine mount a stock length clutch housing is requiredSeparately, it is recommended to enlarge the cutout in the body panel in front of the K & N air filter for about 2 - 3 mm to ensure that the panel cannot chafe on the air filter.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.

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. Attention! We recommend to run exclusively fully synthetic 2-stroke engine oil, like y0813 Motul 800 racing oil.
