Yamaha Jupiter-Z, Balancer Lightest

  Jupiter gacoan Diaz Kumoro Djati not overtaken in MP1 (125cc) MotoPrix Series VIII, three Circuit Week at Expo Kemayoraan JI. Although at the end of the second race but still won mbrebet 2. The key, all-round light machine setup.
"Settings light adjusting circuit Kemayoran ago, which made rolling speed," said Heru Hardianto, the head mechanic at a Yamaha TDR Federal Oil NHK FDR Yonk Jaya.
Rumble in the balancer mild example. Made only 375 grams. According to the mechanic called Heru Kate's well-known, including the lightest size that much. In order to increase the engine turns faster because the track circuit is dominated corner rolling speed.
Straight tracks can be said only 170 meters short. Do not need a heavy pendulum already quite accomplished. Provided that the compression ratio is also contrived low aka lightly.
To play in Kemayoran yesterday pegged compression ratio 12.8: 1. Though usually can be up to 13.2: 1. But in order to compensate for it the way a light balancer to lap down, compression must be made low. Surely that top-speed is also achieved.
Magnets are also made lightly. Because abis turner. "Weighing at only 400 grams," said Heru is headquartered near Stadium Maguwo, Sleman, Yogyakarta.


Apparently this is what makes Jupiter mbrebet in akir lap. Rupture due to the magnetic turner too thin. Shouted the machine would not like a gasoline shortage.
Other settings on the ratio remains the same for each circuit impromptu. But the difference is only on the sprocket. This time using a 14/43.
For the choice of using a size 29/24 mm valve. While the duration ranged kemnya 273 degrees. In the valve open approximately 35 degrees before TDC (Top Dead Point) and closes 58 degrees after TMB (Bottom Dead Point).
Kemnya made twin. To adjust the track live set itself forward-pullback. Made clear its duration remains the same.
According to Heru, from the beginning of this bike so, setingannya same. Most adjusting circuit only. For holes in and ex also remain the same.
Elevator KemOr high lift valve opening is determined by a ridge or bump on the back. Some mechanics do have the opinion of each of the lift valve.
As a mechanic Kate Heru-Yamaha Jupiter Z geberan Diaz Kumoro Djati of FDR's Federal Oil Yamaha TDR Yonk Jaya's NHK. He's got his own benchmark.
Although the same duration, Heru peg back exhaust lift higher than the suction. This theory is the opposite of some other mechanic to fix it even higher suction valve lift.
Heru pegged back suction elevator while the elevator 9.4 mm 9.5 mm dump valve. "Lift the higher exhaust valve 0.1 mm," explained the mechanics of the original scholars of Agriculture of the University's Veteran Yogyakarta.
According to Heru anymore, made that there must be intent and purpose. Namely, in order not to wet the engine settings. So that the breath machine becomes longer. Rpm engine capable of long shouts
