Why would i be getting all indicators on when i turn the right indicator on and where is the indicator flasher relay
its not that simple. be systematic, use a multi meter and try isolate where the problem is crossing of thing you know is right 100%. to be honest your problem is likely an easy fix but u should learn the bikes wiring because I promise u more problems will occur.
Have you just changed to LED? If so, sounds like you're getting "feedback" current (that's what I call it anyway) because the LED's aren't rated to the current normally supplied by the circuit for the old bulbs. It means the current is too high for the LED circuit so they all sorta go a bit haywire. Resistors will fix it or a replacement LED compatible flasher unit... try thirdgear.
Depending on year etc, usually up near the rear of the seat on the left side CBR250R has a flasher up under the left side of the dash, it has 8 wire's going to it
