To all those who are facing missing issue, it is mostly related to mixture setting.
The stock setting of YBR from factory is lean , dont know why they did it. If anyone of you visit Shareef auto's he will tell the same story to everyone, that petrol isnt of good quality, use high octance , this and that. However after many time complains he still wont change your mixture setting, dont know why.
If you continue forcing him after repeated visits then he might adjust your mixture setting.
To all those who are frustrated from missing, This bike has a butterfly carburetor and mixture is on air.
There is a small screw at the bottom of the carburetor,
If you want a Rich mixture, turn screw clockwise (Less air, more fuel)
If you want a Lean mixture, turn screw anticlockwise( More air, Less fuel)
My suggestion is to turn the screw clockwise just (1/4 turn) and check, if problem is there , turn more (1/4 turn) (Total 1/2) turn with a small watchmaker flat tip screw driver.
Hopefully it will remove the missing issue.
Also Check your air filter, it should be dust free and cleaned
