Need help. My girlfriend's CRF 150 will not run without it being on half or full choke. As soon as the choke is switched off, the bike will shut off. The plug is white, which means it is lean so I richened up the needle one position and the main one size (112). Still has the same problem if not worse. It actually ran better without the rich settings. The bike runs like crap through all throttle positons. It just started this too. Brand new, it ran fine with it's current settings. It slowly started to get lean. First it was lean on top now it's through all throttle positions. The bike has about 25 hours on it and we live at 6300 ft above sea level. Any suggestions would be appreciated. Thanks.
