Yamaha YB125Z Issues Discussion

[studbr00d]

AOA brothers,

I am starting a new thread so that all YB125Z issues faced by everyone can be discussed here:

I am from Karachi. Recently purchased YB-125-Z. I am facing the following issues:

1. Agar bike ko open parking main kaafi dair khara chor dou tou start hotay k sath hi off hou jaatee hai. RPM keeps dropping and it gets off. After about 4/5 attempts and applying manual throttle for one minute, the bikes RPM get stable. What shall be done?

2. Bike slips on applying rear breaks. I am still in Break-In period. So in any case, I don't go above 50 Kms/hr and 4000 RPM. Still, on applying EMERGENCY breaks, the bike always slips. Is it the rear tyre that needs to be replaced or something else? By default, Service tyre is installed. I am maintaining the Yamaha recommended Air pressure in both Tyres.

3. Karachi main tuning kahan se karwai jai? I went to Huzefa Autos opp. Alladin Park Gulshan for an oil change at 350 Kms. They seemed just like any other normal mechanic.

I noted my bikes fuel consumption at 336 Kms and it was 48 Kms / L while riding at a maximum of 50 Kms / Hr and 4000 RPM in City.

I went to Huzefa Autos (Karachi) for the issues resolution. They said that the rear wheel needs Wheel Through done. The rim is not in shape.

Does this make sense that a new bike needs wheel through? Its slipping from day one.

I purchased YB-125-Z. I am facing the same issues which are mentioned above following issues:

Raat mai bike park kerdo or subha start kerney ki kosish to start hotay k sath hi off hou jaatee hai but I adjusted RPM as per my own it is working fine but I went to the service center they adjusted as per company so issue is starting again.

Bike slips on applying rear breaks. I am still in Break-In period. So in any case, I don't go above 50 Kms/hr and 4000 RPM. Still, on applying EMERGENCY breaks, the bike always slips. Is it the rear tyre that needs to be replaced or something else? By default, Service tyre is installed. I am maintaining the Yamaha recommended Air pressure in both Tyres.

Kindly give suggestion(s) and advises.

I copied question from above because I am facing same two issues.

Idle recommended RPM is 1300-1500, but when you will start in the morning it will start at 1000. So for first 3-5 minute hold your accelerator for a bit and as soon as you feel it is now stable leave it, it won't turn off hopefully.

I am also in break-in period and never experienced slipping. You are either pressing it in a panic mode, if so it's normal the bike should/could slip. Try using front and rear both break gently and maybe this won't happen.
