Has anyone replaced their carb with a different unit? I have a 2020 Raptor 90 with a no name carb on it and have nothing but problems with it. I am really disappointed in yamaha right now. I purposely didn't buy a chinese quad because I wanted a better quality bike for my son.The carb has been cleaned, rebuilt, and cleaned again. I only use non ethanol fuel. I am at my witts end with this thing. Any help or advise is appreciated. Thank you.
