y1419 Sintered steel clutch for Zenoah and many other engines from 23 cm³ to 32 cm³
Sintered steel clutch for Zenoah and many other rc-car engines from 23 cm³ to 32 cm³.Note: The sintered steel clutch needs a break in period of at least half an hour run time after their first installation. Only then the clutch surface reaches the desired grip and provides the necessary friction. After that the clutch will show consistent operation and extremely low wear!With 80 grams the weight of the clutch is about the same as the usual OEM clutches.As with all non-adjustable clutches a periodic monitoring of the clutch spring is recommended. By changing the spring, it is also possible to match your car to the track conditions, i.e.: the harder the spring, the higher the stall speed of the clutch.If not on hand, for installation of the sintered steel clutch a clutch spring, the Zenoah screw set # 7318 and the original Zenoah clutch mount # 7315 are required!

y1610 SPEED TEC Expert 7-port Zenoah G320 modified engine
The SPEED TEC 7-port genuine Zenoah engine is optimized for performance by hand with sophisticated craftsmanship and guarantees, besides greatly increased performance, excellent workmanship and stamina. More power and torque through the three additional transfer ports.SPEED TEC V 7-port version modifications: Cylinder:Cylinder bottom modified for higher compressionenlarged and flow-optimized transfer portsmachining of three additional transfer ports raises number of ports from 4 to 7intake and exhaust ports optimized and matchedport timing modifiedCrankshaft:is adjusted, aligned and balancedFlywheel and ignition:Weight reduced and checked for run-out.Gaskets:Premium quality gaskets installed. Cylinder gasket installed using elastic gasket sealer.With the new "K & N" version of the Losi DBXL there is another detail, which need to be considered.From the very beginning the hole pattern for the engine installation in the DBXL chassis plate was no precise match to the hole pattern of the engine, even when delivered in stock form with standard engine. 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.For 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 a Zenoah G320RC in a Smartech C5 onroad car is possible without modifications. However, due to the engines performance aluminum engine mounts (set # y0189) are mandatory!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. 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. Attention! We recommend to run exclusively fully synthetic 2-stroke engine oil, like y0813 Motul 800 racing oil.
