Here you will find all the heads still available in the market to style your large kits diameter of your Peugeot 103. When installing a cylinder head high compression, please always ride with the SP98 (admittedly more expensive but you can also make more km and offers more performance), be sure to check your carburetor settings to not ride with a lean engine (white candle). The ideal is to control its squish order not to ride with a tight squish. Most experts also can control the volume chamber and deduce the best for exercise with fineness of seal used. On our 103, there are heads decompression with or without decompression, the decompression valve turns off the motor and starts the easier has the buggy by simply opening the room and sending all the gases in the exhaust directly without the compress. For the performance, the best is to take a version without decompression and install a universal neman turning on and off the moped, the tube pierced in the exhaust pipe and the strain in the head caused by decompression are not friends with performance! The tightening of the group cylinder head / cylinder ... sure if you ask a good head to take a high quality cylinder head gasket. Opt for stud game MALOSSI reinforced as well as a cylinder head nut game reinforced BIDALOT or MALOSSI. You will shake your head staggered little by little and for this to be the perfect couple 18nm if you have a nut / bolts original group, and from 22 to 24nm if you have the group studs / nuts MALOSSI / BIDALOT.
