[I need to know whatt to do . My bike will hardly start. It is A CRF 150 I removed the snorkel and it ran fine for 1 day Then The next day I let it idle for like 7 minutes and when I was ready to ride It wouldnt rev. I then shut it off And whenever I tried to Start it It would only run on half or full choke. by the way it is about 40-50 degrees colder than usually.And im working on putting the power up kit in. Ive ordered a thrust nozzle from powroll.
Needs to be richened up. Pulling the snorkel let more air in, and the colder temps mean denser (more) air on top of that. Time to re-jet and adjust the pilot screw on the carb.
