when you press your throttle, you'll feel like there is 2 stages.. this is true for progressive carbs (hitachi 306). only enter the second stage/secondary jet at rpm above 3000... so press the secondary according to the speed below

1st gear >22.203kmh
2nd gear >35.945kmh
3rd gear >56.604kmh
4th gear >78.000kmh
5th gear >95.003kmh

so only activate the secondary barrel after the speed above according to the gear position respectively. I got a table of the 60A gearbox's gear/rpm/speed in excel format.

5th gear >95.003kmh


is that the optimal speed for 5th gear??

but what if we go slower than that?? or go faster??

as i know..it will only go more on fuel consumption if lower or higher...

:unsure:

:unsure:

that is the best time to change gear la... you can go below or higher. at 93kmh, the 4th gear is at 3400 rpm, the max torque for A15, A12 engine
