Question about 2002 Yamaha V Star Classic
Posted by Anonymous on
Hi, Anonymous it should be noted I am not allowed to use the word "SCR*W" as Fixya considers it profane. The carburetor throttle shaft wheel has two cables the cable closest to the right side of the bike is the throttle cable and the one closest to the left side is the idle cable. Right about the middle between the two is the idle adjustment bolt. It faces out towards the air filter end of the carb . The engine should be at operating temperature with the enrichener off to set the idle between 950-1050 rpm. Turn the bolt clockwise to increases idle speed and counterclockwise to decrease idle speed. If you have access to your air fuel mixture bolt you may adjust it as well if not there is a video below on how to gain access, make sure you start with clean or new spark plugs. Gently turn the bolt clockwise until it starts to bottom out "STOP" do not over tighten as it will damage the taper on the bolt, now back it out 2 full turns to establish a starting point start the engine and check the idle rpm's and adjust the idle bolt accordingly for 950-1050 rpm if necessary, adjust the A/F mixture bolt 1/4 turn at a time and let the engine settle for about 10 seconds, clockwise for a leaner mixture and counterclockwise for a richer mixture you are seeking the highest rpm your A/F bolt can acquire without going past 3 full turns from bottom then readjusting the idle bolt back down to 950-1050 rpm If you can not detect any rpm change and can not stall the engine by turning the A/F bolt all the way in then your pilot/low-speed jet is too big. Final adjustment should be made with a clean air filter mounted to the carburetor.

under the left side of the gas tank you will see i black knob/screw at the end of what looks like a hose. the knob faces the rear of bike. that adjusts the idle. its real easy to find and the only adjustment you can make to the carbs.
