Simple mechanics add much needed boost.
  
The first and one of a kind 3-valve per cylinder, 4-stroke SOHC engine displaces 109.15cc. The 10cc upgrade is derived by increasing the bore to 53mm with stroke length retained at 49.5mm compared to the previous 99.1cc unit with a bore size of 50.5mm increases max power to 8.9bhp (at 8500rpm). Though the 0.4bhp increase in power over the 8.5bhp of the older unit may not seem significant, the new engine develops this power at a lower 8500rpm compared to the older unit where power surges at a higher 9000rpm. This results in generation of a greater 8.34Nm of torque at just 6000rpm. Higher torque at a lower rpm essentially translates to reduction in downshifting to call on requisite power. An added advantage should be lower fuel consumption, which will be delved into later. This time around LML has sacrificed top end grunt for increase in mid range power to improve driveability. Further, the 3-valve configuration allows better combustion than any 2-valve unit by improving power and increasing efficiency. A Keihin carburettor with the same 18mm venturi improves overall Performance. The frequent stalling of the engine in idle could primarily be due to a lean burn setup.
  
The gearbox on the Energy FX involves an all-up shift pattern as opposed to the older unit. While the Adreno FX makes do with the universal one-down four-up pattern. The increase in ratios matches the power curve of the engine. The shift quality is slick and slotting into any gear requires only a gentle tap. There was never a false neutral encountered in over 300km. Another plus for the LML siblings!
