AIR-cooled cylinder kits CYLINDER KIT Wash all the components of the modification system with petrol and blow them with compressed air, making sure in particular that there are no foreign bodies in the ports of the new cylinder. Use engine oil to lubricate the cylinder liner, the big end and the roller cage after having carefully checked the latter and replacing it, if necessary. Some cylinder models have a reinforced roller cage;... - Page 4 2) Inserting the CYLINDER and aligning the PISTON Fit the base gasket and feed the piston without rings into the cylinder. Push it down to the crankcase making sure that it goes right in without any friction, leaving a minimum of play in its crankcase housing. If there is any friction look for the causes of resistance and remedy them. Then secure the cylinder to the crankcase using the relative nuts, inserting spacers in place of the head.
- Page 5 1.2 Kgm. N.B. Malossi heads supplied with O-rings must be assembled directly onto the cylinder without the insertion of any other gasket or sealing grease. 3) CULASSE d’origine Nettoyez les résidus de la combustion sur la culasse d’origine;...
- Page 6 YAMAHA CT - 31 6901 HEAD Fig. 1 Kit includes a union and a threaded adaptor to be fitted to the head as shown in the Fig. 1. The components, along with their relative screws, are included in the kits and are for securing the forced cooling air feeder casing (art.

LIQUID-cooled cylinder kits CYLINDER KIT Follow the instructions given in points 1 and 2 under the heading Cylinder Kit - AIR-cooled version (pg. 3-4). HEAD Carefully clean the bottom of the cylinder and use compressed air to blow the O-ring slots. Fit the thermostatic valve with relative gasket and bleed pipe, where envisaged, as shown in the figures on the following pages according to specific application (pg.17). -

If you wish to retain the original carburettor you will have to replace the main jet, if included in the kit, or else position the needle on the fifth and final notch from the top (basically the pin must be fully raised). With this method performance will be good, but not comparable to that of a scooter equipped with a specifically designed Malossi fuel supply system. - Page 9 Pour les modèles avec pompe à débit variable, étalonnez la pompe suivant les instructions indiquées, à l’aide de la vis de réglage du câble de transmission. HUILE LUBRIFIANTE Nous vous conseillons d’utiliser de l’huile de synthèse MALOSSI 7.3 et en cas d’utilisations sévères de l’huile 100% synthétique MALOSSI 7.1.

Contrôlez que les bagues d’étanchéité ne sont pas bloquées et vérifiez-en l’usure dans le point d’union. La lumière ne doit jamais dépasser les 7-8 dixièmes de millimètre, sinon remplacez les bagues avec des anneaux spéciaux d’origine MALOSSI. NOTICES GENERALES Si le groupe thermique est démonté, remplacez les joints de culasse et de base du cylindre par une nouvelle série, afin de garantir une... - Page 11 TECHNICAL FEATURES cylinder kits CAST IRON CYLINDER -- Technology - Material: special self-lubricating, wear-resistant, highly refined cast iron alloys, obtained by Shell Moulding gravity die-casting. - Machining: on numerically controlled high precision machine tools. - Recalculated heat exchange surfaces. - Exhaust and transfer ports designed and tested for maximum thermodynamic performance. - Shape and surface texture dimensional checks.
