Hey guys, I recently bought a 2012 crf450 and absolutely love it. However, there's an issue with the throttle bogging when you snap the throttle wide open (completely closed to wide open). This isn't normal I don't believe, or from what I have seen with my friend's crf450 EFI his wont bog whatsoever. Does anyone know what this could be or could tell me a good place to start? Bike has a Yoshimura RS-4 exhaust only, and I don't know of anything else that would effect throttle response. Lastly, the previous owner had adjusted the revolver throttle cable on one side tightening it up an1/8th inch, but I checked free play and it seems to be in spec and correct. Any help is appreciated, I am new to the EFI bikes! Appreciate it guys!
