Suzuki DRZ400S Not Getting Enough Gas
This bike is known for running lean and having to have the carburetor adjusted to run richer. But before you start working on the carburetor, look at the fuel supply first. These bikes are also known to have fuel petcock valve issues which cause the Suzuki DRZ400S not getting enough gas.

If your motorcycle is running lean, and that is any model bike. Look at the fuel supply first before tearing into the carburetor. I have seen many people start turning screws and trying to make all sorts of adjustments to the carburetor when in fact, it was not getting the right volume of gas to it.
You want to check your fuel flow first. If it seems restricted, check your fuel filter screen that is built in most petcocks. If that is clean, look to see if the bike has a vacuum operated shut off valve built in the petcock. This type of valve is most common. First ensure it is getting vacuum to the valve. If so, using a vacuum pump or just use a hose and suck on it with your mouth, and see if the gas flows out of the fuel line properly.
So if your Suzuki DRZ400S Not Getting Enough Gas, follow the above steps first before messing with the carburetor. It is fact, motorcycle engines take more abuse and are under more stress than a car engine is. This will fatigue the rings faster. As the rings weekend, the compression lowers, thus causing you over time to have to make adjustments to the carburetor. However, ensure that you are getting adequate fuel flow first.
