Default Fuel pump

Hi there,
I have a 1992 Honda VT 1100C shadow spirit and I would like to know if anybody has bypassed there fuel pump and just gone right to the carbs.

You can do so - but you will experience a shortened range. The reason the bike has a fuel-pump is, part of the fuel in the tank is either below the carbs, or sufficiently low-enough that gravity-flow to the carb bowls is seriously hampered.

If you're having trouble with the pump and/or relay, and the OEM-replacement is too expensive for your taste - look for a "generic" relay or low-pressure electric pump, or replace it with vacuum-powered pump. All the vac-pump needs is a small port between the carb and cylinder-head. Many moto-manufacturers use them - the first-generation Suzuki SV comes immediately to mind.
