Help on Y125Z

[CoStar]

there is something wrong with the engine i think as the sound comes from there. it sounds 'deeper' than the usual 125z sound..

when i try going at 120km/h before this, it is easy to reach and the engine feels ok.

but now i restrict to 100 as when it reaches 120, it sounds like under a lot of stress and the rev is higher. it is hard to reach 140..which is possible before..sounds like engine going to xplode. i occasionally go this fast..not always. plus.. there sounds like something loose in there.

 

any experts can 'diagnose' for me?

 

 

i went to mech to repair..they change cdi and full service but still same. my fren say i got robbed.

 

pls help.

When you say your revs are higher in order to reach 120km/h from 100km/h.

Sounds like clutch slip to me, or incorrect engine / transmission oil?
