| 22. Start the bike on the stand, you may need to adjust the needle if the bike is not running well. Tighten it to make it leaner, Loosen it to make it richer. Once the bike will idle, Hold the throttle wide open and tighten the needle to make it leaner. You should hear the bike get louder as you tighten the needle. tighten it until the bike begins to stutter and bog down. Once the needle is in the correct spot, tighten the lock nut into the bottom of the carb to lock the jet in place |
