【KLX250/LX250S】噂の12穴インジェクター(15710-21H10)流用！極上の「もっちりトルク」を手に入れる

車両: Kawasaki KLX250（LX250S / インジェクションモデル）

今回のカスタム: 純正インジェクターから、スズキ純正の「12穴インジェクター（品番：15710-21H10）」への流用交換。

カスタムの狙い: インジェクション初期モデル特有の、低回転でのドン付きやトルクの薄さを解消するため。

結果: 燃料の「霧化」が極めて細かくなることで燃焼効率が上がり、アクセル開け始めから粘り強い「もっちり」とした極上のトルク感が生まれました！

Vehicle: Kawasaki KLX250 (FI model LX250S). Topic: Improving low-end torque and throttle response via a fuel injector swap. Details: Many early fuel-injected 250cc models suffer from a jerky throttle and thin low-end torque due to lean emissions tuning. Today, we applied a well-known, highly effective trick: swapping the stock injector for a Suzuki OEM 12-hole injector (Part No. 15710-21H10). The increased number of tiny holes creates a much finer fuel mist (better atomization). This allows the fuel to mix more thoroughly with the air, significantly improving combustion efficiency. Verdict: The result on the test ride was incredible. The bike developed a rich, tractable, “sticky” torque at low and mid-RPMs, completely transforming the low-speed rideability. A highly recommended mod for KLX250 and D-Tracker X owners!
