What kind of fuel can I put in a crank case?
I dumped about 4 qts of fuel/oil (mostly fuel) from the crank case, and the fuel tank was empty. Clearly, fuel has been getting from the fuel tank to the crank case. After putting in fresh oil, I got it running but after about 5 minutes it quit and wouldn’t restart.
What’s the best way to drain a fuel tank?
Unscrew the drain plug and let the fuel drain. This will take a long time, up to several minutes per gallon, so you should keep an eye on it. Make sure to have more than enough drain pans to catch all the drained fuel and to make sure no fuel is spilled onto the ground.
What to do if you have gas left in your tank?
Place a pan or receptacle underneath the drainage plug. If you have several gallons of gas left in the tank, you need to be prepared to catch it. This is easier said than done, so try and gauge how much gas is in the tank before beginning and have the appropriate number of containers on hand before starting.
How does gas get into the carburetor bowl?
Generally a small vacuum line is attached to the number one cylinder vacuum port. Every time the piston goes down, it creates a pulse of vacuum to allow gas to enter the carburetor bowl. Therefore, if your engine is not running due to a crash or being stored, no fuel should get from the tank to the carb.
What should fuel valve be in when bike is not running?
When the bike is not running, the fuel valve should only supply fuel in the prime (PRI) position. When in the on or reserve positions no fuel should be supplied. If fuel is flowing freely, your petcock has been either altered or has internally failed.
What should I do if my fuel valve is leaking?
First, remove your fuel supply line from the petcock. Then unplug the vacuum line at the back of the fuel valve. When the bike is not running, the fuel valve should only supply fuel in the prime (PRI) position. When in the on or reserve positions no fuel should be supplied.

What happens to the crank sensor on a GMC?
The crankshaft sensor on GMC vehicles is synced to the powertrain control module, or PCM. When the crank sensor is replaced, it must be resynced to the PCM. Without resyncing, the PCM cannot properly determine the position of the crankshaft.
How to relearn a procedure on a GMC after changing?
Without resyncing, the PCM cannot properly determine the position of the crankshaft. The proper procedure for resyncing or relearning the crankshaft position is called the “CKP Variation Learn.”
