Fauzan,

 

I can only reply from my side being the CVT. We never came across this kind of noise that was CVT related.

I would think of torsion damper (between engine and CVT), do you hear anything when foor on brake standing still TM shifted to D?

 

Best regards

Hi Kristof,

I hope you are doing well and enjoying your weekend. I have a question bugging me about my Saga FLX SE 1.6 (8 months old).

There is apparent, loud, (not whining sound, but quite rough) noise when I press pedal to around 2500rpm. The range for the loud noise is very narrow, when I release pedal a little, the noise goes away. Or I step beyond 2500rpm to around 3k, the noise goes away as well.

This also happens everytime when I floor the pedal. does this has something to do with CVT mounting?

looking forward for your answer.

Thank you.

Regards,
Fauzan

Advantages of the CVT

'Engines do not develop constant power at all speeds; they have specific speeds where torque
(pulling power), horsepower (speed power) and fuel efficiency are at their highest levels.
Because there are no gears to tie a given road speed directly to a given engine speed, the CVT
can vary the engine speed as needed to access maximum power as well as maximum fuel
efficiency. This allows the CVT to provide quicker acceleration than a conventional automatic
or manual transmission while delivering superior fuel economy. '

why i cant feel the fuel economy now?~ T^T
rm50 half tank 140km only~ owh Gosh~
