My 2001 yamaha raptor has a fuel leak from the bottom of the carburator can you help?

There are two possible reasons for this - firstly there may be a crack in the carb. bottom. On ly solution is to drain carb, remove bottom of carb and replace with new one (that is if they are available singly), the other problem might be that the gasket is leaking that seals the bottom to the carb body. Check the screws / bolts that hold this bottom part on and see if any are broken, missing, or just loose. If the anwer is no to these questions, the gasket might still have failed. Drain the carb after switching off the fuel tap or disconnecting the fuel tank, once drained remove the carb bottom and check the rubber gasket for swollen areas, breaks or even a small nick. Replace as necessary.
