In this category you will find all the reconditioning packs to put back your balance shaft of your motocross HONDA 4 strokes. These packs are composed of the best quality bearings on the market so that you don't have to dismantle it regularly. It is very important that it is mounted and in good condition. It allows to avoid all vibrations of the engine movement which could lead to inconvenience during the driving but also break the engine support or even worse damage the engine. We advise to change the engine every time you reassemble it (gasket, crankshaft change etc...). This could avoid bad surprises and therefore have to start all over again.
