How do you adjust pilot screw on Yamaha Venture?
This will fix your problem. The complex way to adjust the pilot screw is to use an exhaust analyzer probe on each cylinder and adjust for 2 to 2.5 % CO and 600 to 800 PPM hydrocarbons. But since the factory gets it close, but too lean, the 1/4 turn method will work fine for you. Pilot screw locations.
How do you put a Yamaha Venture back together?
Notice the path they follow so you can put it back together right. Remove the vacuum advance hose from the left front carb holder and bracket. Unscrew the choke cable retaining screw enough to free the cable (Figure 2, A). Slide the cable housing out of the retainer.
Where is the ventilation hose on a Yamaha Venture?
Loosen the crankcase ventilation hose where it attaches to the crankcase in the near-center of the engine’s V (Figure 1, A). This is best accomplished from the right side. Slide the pinch-clamp up beyond the crankcase vent-pipe contact area. Wiggle it enough so it floats free. Loosen the four airbox boot clamps, one per carb.
How do I open the airbox on a Yamaha Venture?
Slide the pinch-clamp up beyond the crankcase vent-pipe contact area. Wiggle it enough so it floats free. Loosen the four airbox boot clamps, one per carb. Unscrew the clamp almost all the way (screw not completely out of the clamp) so the clamp is floating freely. Work the base of the boot free from each carb individually.
