Hi, Anonymous 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 idle adjustment 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 air fuel mixture bolt clockwise until it starts to bottom out "STOP" do not over tighten as it will damage the taper on the end, 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 adjustment bolt accordingly for 950-1050 rpm if necessary, adjust the air fuel 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 air fuel mixture bolt can acquire without going past 3 full turns from bottom then readjusting the idle adjustment bolt back down to 950-1050 rpm If you can not detect any rpm change and can not stall the engine by turning the air-fuel mixture 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.

5. Carburetor jetted too lean.
6. Leaking intake or exhaust valve.
7. Water coolant old or low change every two years.

9. Radiator clogged, cap loose or malfunctioning.
10. Radiator fans not coming on.
11. Clutch slipping, brakes dragging, heavy load, towing a trailer etc.
12. Idling too long without moving.
13. For constant hot weather temperatures, mountain, or desert riding conditions consider adding an oil cooler and or cylinder head cooler.

Running bike just shuts down (dash goes black too) for a short time (0.5 - 2 secs) then all comes back. Would a bad contact on the battery connector have this effect ? Or is it more likely a bad contact in...
