FuelStarvation

There are a few things that can cause fuel starvation

1. A kink in a fuel line.
2. A blocked inline filter or the filter on the inside of the petrol tank.
3. A the petcock on the under side of the fuel tank is turned off or partially off.
4. The petcock on the side of the bike is blocked or faulty
5. If the main jet in the carburetor is too small or blocked. Disassemble the carburetors and remove the pilots, and clean them in carb cleaner.
6. A dirty carburetor, especially if the bike has been sitting for a long time. This can be fixed by cleaning the carburetors, particualrly the float bowls.

All of these are easily fixable with a bit of patience.

If the problems persist try turning the petcock to prime before long, fast trips, or check the GSTwins forums.
