I suggest you do the valve adjustment again. Here are a few tips to help you with the fuel tank.
Go to your local auto parts store and get some 1/4" vacuum caps. The following package contains 4, which are red in color.

Work on the right side of the motorcycle.
Place an old blanket behind the fuel tank before you remove the bolt which holds the fuel tank in place.
Remove the bolt, and lift the rear of the fuel tank. Slide the blanket under the rear of the fuel tank.
Pull back on the tank to remove it from the frame. Rest the fuel tank on its left side on top of the blanket.
Disconnect the 2-pin connector which attaches to the fuel gauge.
Using a flat screwdriver, pry open the buckle connector which attaches to the fuel pump.
Remove the two hoses from the fuel tank.
Press the two buttons, and remove the fuel hose on the nipple which is pointing upward. Let the small amount of fuel drain from the loose hose. Place one of the 1/4" vacuum plugs over the nipple to seal the fuel tank.
Turn the fuel tank on its back. Press the two buttons, and remove the fuel hose on the other nipple. Let the small amount of fuel drain from the loose hose. Place one of the 1/4" vacuum plugs over the nipple to seal the fuel tank.
Remove the fuel tank from the motorcycle, and set it aside in an upright position. Now you will have enough room to adjust the intake valves.
Set all four valves to 0.08 mm. A little too loose is better than a little too tight.
After the valve adjustment is done, replace the fuel tank by following the steps above in reverse.
