Dear team
Greeting of the day
My Bike is CT125 x, purchase on March 2023 and my bike only run 10000 but my bike engine is open 2 time.
on 2nd service of my bike service center employee open my engine to install new wall and then 10 days after 3rd service my bike will not working on the mid of the road so I tow the bike and send it to the same service center, now they change my timing chain.
