I have a rs200 2016 model, when the bike goes into gear-3 & 4 or rpm[protected] this is a big missing problem.
I was go to Bajaj Service Center, they replaced the fuel pump, then it did not respond well.
After that the mechanic replaced the throttle body and then they did not work. I do not know what the major problem is, please help me,
If you have no choice, please give me the real value of my bike and the chance to replace it.
