Try to take part in the Asian Grand Prix FIM Asian GP aka Ibn Sambodo make different preparations. Chief mechanic Kawasaki Elf Team IRC NHK Rextor M-Tech is kudu prepare appropriate regulatory machinery Asian GP. Admittedly, Blitz machine Hadi Wijaya besutan that will fall on the 110 cc Underbone later spec-down of the modifications in Kejurnas or Indoprix (IP).

"Although the spec-down, this machine better than that used in IP Series 1 Sentul. God willing, with the support of work and prayer, to give the best for the Red-White till the finish. My standards of dynotest results. 19.1 dk obtained for Sepang, "said Ibn be accompanied by two other mechanics of the team.

Regulation requires that the Asian Grand Prix, 115 cc engine capacity. Rules are similar Kejurnas. But, Blitz can only 113.3 cc. Because you had a piston diameter of Ibn only 53.4 mm. "A maximum of 53.75 mm based regulation. If we had a piston So much, can add 1 percent more power than they are now, "said Ibn.

For the valve, the same rules, a maximum of 29 mm. But Ibn pake suction valve 28 mm, and 23.6 mm exhaust valve. This valve Ibn modification results, rather than foreign goods. Because even though he promised not to use foreign components. Except for the part that can not be modified themselves.

True size of the valve is not ideal. But, forced by the piston bore Blitz was not enough for maximum valve width. "If forced most to lose. For the record, 28-mm valve was almost close to the ideal needs 115 cc engine, "said Ibn.
Comparison of compression for the engine fuel Pertamax Plus or Petronas, is 12: 1. Kalo pake in Kejurnas Elf, 12.6: 1. Said Ibnu, a decrease of compression is also nurunin power. Because, with the spec Kejurnas, Ibn estimates, Blitz can reach 21 dk.


Kem always be part interesting. Moreover, if this machine made the 'Begawan 4-stroke'. Blitz Camshaft duration is set 280 degrees, measured at 1 millimeter of the valve opening. The elevator was made 9.4 mm, both in and ex. "Sorry, another thing that became a secret workshop," honest ibn whisper.

Oooo ... so! Honestly, yes?

Asian Grand Prix once again have a somewhat different regulation. The challenge for Ibn, he had to enlarge the mouth of eliminating the carburetor. Therefore, the regulation forbids the Asian GP changes in the carburetor venturi diameter of 24 mm.



Unfortunately, Ibn do not have the engine performance data with the prepared fuel committee. So take time to jeting day at Sepang, 10-12 April. Cilakanya, this affect engine durability. Ibn tactics, will be considering the circuit. Starting from humidity and temperature. "Yes, should see the weather forecast on the local television and local people said," Ibn relaxed.
