I am looking to grab a 2012 BruteForce 650. It is in pristine condition as it only has 307 miles on it. However he has only used regular (not ethanol free) fuel in it. It is not running very well at all. He says he was told it would need a carb cleaning. Which would be expected with this few miles. Is there anything else I could expect to be wrong with this scenario? Maybe a fuel pump? I was hoping to drain all the fuel out, clean up the carb real good, add new ethanol free fuel and hope its like new? Help me know if there is something I may be overlooking? Thanks.
