Can anyone tell me what exhaust this is? I’m asking because i have a air/fuel ratio issue that causes my bike to hesitate in 1st gear but only when going up a hill. I don’t know if my ECU has been flashed but my thoughts on sorting it it out are 1. Buy an unflashed ECU 2. Buy a stock 06 exhaust. Or 3. Send me ECU off the next matched to what my exhaust is.
