Need help jetting my son's CRF 150. Bought new last month. We live at sea level in central California. We have removed Air box and Muffler restrictors. Have moved needle clip down one notch (Needle up). Pilot jet is out 2 1/4 turns. No other changes. Bike takes an awfully long time to start when cold. Starts and runs good when warmed up. Also what starting ritual do you use? I can start my YZ426F first kick in any situation, but not this little red devil when cold. Thanks for your help!
