MODIFIKASI Yamaha Tzm 150

The first motor out capital range of Rp. 20 million has exciting story, one of the owners are in the region Deny Khacif Perum Wiguna, Surabaya. "The year 1993 was the height of the battle type of motor sport.

At that time, Yamaha RX-Z compete with Honda's stringent NSR and Suzuki RG-R and winer NSR in the arena of road race, "Deny the light that follows the history of TZM.

"But That's when playing at the Sentul circuit with a typical high speed, because NSR has been equipped with the RC-Valve or the extra ports to maximize power in gasingan top," said Bambang "Kancil" Sumadji from Audi Motosport Balongsari Tama region, Surabaya.

"While market dominated senggolnya RX-Z and RG-R," he continued. By the end of 1994, a sports competition hotter. "Because, in the year it also launched a variant anyarnya ie Yamaha TZM-150. Suddenly, in that year TZM be king sport, tracks and high speed senggol markets remain TZM warlords, "said the Kancil which happened to the time greeting probe TZM riders racing drivers Jingwan '94 era.

Until finally 150 cc sports class tune up closed in late 1996, owing to strong political control of the organizers manufacturers, "said Daniel Tangka who was then also fell in Sentul together Dwi Cahyono, Selly Momo, Dian Kampret, Momo Harmono, George, Jingwan and Asep Hendro spur TZM.

Necessarily so since the year '95, TZM enthusiasts racing. For a real alternative to buying a sports bike is not much choice, after the NSR and the Ninja. In view TZM has a rich and luxurious features. Front disc rear, delta box frame, full fairing, tank cap moge model, Enkei rims.

"While the sector supported the radiator and the engine is equipped Yamaha Power Valve System, a technology assistant exhaust hole with electric mechanical principle is similar to the RC-owned Valve NSR," explained Kancil. Then what is necessary, replacement at 16 years old tread?. Just follow the narrative they are!. | Pid

Clutch lining
Equivalent to those used Yamaha YZ-125, this is one that causes attraction of TZM responsive. cool again, the number of brake clutch that is used seven layers. Thus the brake skid so minimal. But in practice, the brake clutch 125 YZ-known expensive.

So, the trick to replace the clutch home should be done to save on maintenance. "The alternative could be to use the clutch home or RX RX-Z-King, and then riveted with secondary teeth orsi TZM. That way, the replacement of brake clutch can wear or RX RX-Z-King, "trick Daniel.

Balancer Weight
Breakthrough latest innovations at the time, Yamaha claimed a larger engine capacity 2 stroke, the vibrations generated also increased. In addition, the large torque required to launch a high speed when the engine power, which tends to decrease torque value.

In its use, Balance weight frequently experience bearing sector deviations in the normal method. Therefore, weight bearing on the nature pounded Balance kept by a single drive gear shaft with the primary teeth, as their driving force.

Besides a higher position than calter bottom, making it even more minimal lubricate engine oil. "If until the hissing sound or mbenging arise when the 5000 rpm, check the bearing balancernya," pointed Kancil.

Final gear
Embrace comparisons 16-49 428 chain type, the problem with the contour of gear behind other conventional motors. For a larger hole in its center, here used to adjust the space side of the swing arm.

So in replacement gear behind the rear gear can man-eater RG-R or RX-Z approached 49. Then the mall with a hole in the middle seat orsi TZM rear gear, including bolts of his hole. MODIF making this rear gear, better order it in the shop lathe to ensure the resulting balance is zero.

Double reed valve
One drawback second machine did not, because the experience of dependence with reed valve or membrane. As the operating opening and closing when the entry of fresh gas into the hole and rinse the cylinder, in accordance with the principle of vacuum.

Specification deviation occurs frequently causes membrane leaves no precision or mullet, considering the article is made of Teflon processed. Negative impact when it leaves the membrane was not precise, the engine during deceleration look impressed. Engine Brake so obtained minimal.

"To menyiasatinya type of competition must be replaced, like the V-Force III which has the same dimensions. Also embraces a double reed valve, "Deny suggestions.

Piston
Typical embraced over square engine, piston diameter 59 mm and 54 mm stroke. Here there is no term measures oversized piston and piston size TZM just side adheres AB. Tolerance limit of 0.035 mentioned standard. Why his clearance piston-cylinder big enough? TZM apply for a cylinder type electrofusio n, where it has a cylindrical surface pore in the micrometer scale.

Expansion points generated is almost equal between the piston with its cylinder. But the case of worn piston could also be avoided, even if it could RX-King of the piston 100 over size (59 mm) piston metal profile feared RX-King is different from TZM.

From this consideration, ideally cylinder liner wear pretentious conventional systems. Ported continued with the addition of seven holes and two extra rinse port and a main port (exhaust). "Here the thickness of liner also has a limit. Because if it's too thick, the profile of the steel liner would be difficult stabilized temperature by the radiator, "explained Kancil.

Karbu
Low compression ratio 6.0: 1. Thick with the smell of durability which are prioritized and TZM, a quick review of the comparative figures if the compression is still lelet. But try to trace the teeth ratio, istimencos. Dental 1 (34-12), 2 (29-16), 3 (26-19), 4 (24-21), 5 (23-23), 6 (21-24).

Jadi concept of the engine, the compression ratio low alloy gear haul light ratio, this should be used as a guide nih a tuner tuenr drag and road race. Teeth 4 and 5 thick with speed, was used as the successor tooth 6 cuman.

"When viewed from the acquisition of graphics power at top speed then the determining factor of the fresh gas supply of the Mikuni VM30 SS. Age 16 years was also not easy for TZM and karbu like experienced replacement. More sip if replaced with skepticism Mikuni 30 mm oval sizes too, "Daniel has ever aplikasi details.

Radiator
For the lattice-lattice must digurah with wire, to remove scale and mucus. Continue rinsing with hot water. Therefore, this section certainly more ngendon crust. After ensuring a good radiator grill lines, continue to check the thermostat function.

In accordance with the specifications, the thermostat valve opens TZM while at 65 degrees, to the needs of the radiator water circulation. In accordance with the physical and mechanical thermostat, the deviation is common in the gasket began to crack. Causing leakage of water circulation.

Special gaskets must be made alone, because of gasket wearing leather and there's no market. For ingredients, can car garage. "This type is usually used as gasket sheet pan gasket calter car engine," explained Kancil.
