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.

Genuine Mielke spare/option part. We took a very long time to test this mufflerer thoroughly and to test and compare small changes again and again already in summer 2017 on different vehicles on different race tracks. All experiences were then analysed in detail and combined with the bench tests from last year and, of course also from winter 2018, to the current final product no. 5900.The very good results and the weight optimization (titanium is approx. 40% lighter compared to steel) along with the great racy look should give us a perfect tuned pipe system for 1/5 touring cars.Modified engines, which are widely used, are especially grateful for the low thermal expansion (approx. 40% less) and the high temperature resistance (perfect for exhaust gases).The material used is only 0.7 mm thick and yet very strong.Combined with the very well tested Masterfix connection (3 springs connect the manifold to the pipe) and the Teflon gasket, which has been tested for years, there will also be no problems with the connection to the manifold.Contents:1 piece
