Baya 250cc - full speed not enough gas ?

[brox]

Hello friends,

when I ride my bike and I want to keep my bike at maximum speed (throttle is full open) it dies after a minute or even earlier.

It looks like it doesn't get enough gas when opening the throttle at max.

Any ideas and suggestion what I could change that the engine get's at max speed enough gas ?

thank you so much for any little help.

It may be the tank not venting. With about a half tank open the gas cap and go try it. If it it keeps going your tank is vent is plugged.

Next I would check the fuel lines and petcock for flow.
