Question about 1998 Suzuki VZ 800 Marauder

1 Answer

2003 Suzuki vz800 Maurader suddenly went down to half power as I was ridingon the highway. It allowed me to get home at 50 mph but was unable to accelerate. Now I can start the bike with the choke out with no problem but if I give it any gas at all it stalls out, with or without the choke on. Fuel pump is pumping out gas, the carbs are clean and the floats are working and I have spark to the plugs but I am unable to ride my bike. Tony

Please check your exhaust pipe or the silencer. It must have been chocked with carbon and you have to remove the carbon deposit to run your motorcycle.

Also clean your fuel tank as it could have dust deposits at the bottom chocking the fuel flow once it is in running condition.

Please change the spark plug as recommended after covering a distance specified.

I have a 2001 Suzuki maurader vz800,it runs okay at idle but doesn't have a lot of power at load


Have the timing checked first. It may have slipped because of a worn timing belt. The engine control module can be in the limp in mode if it has failed .

How do you change the plugs on 2000 Suzuki maurader vz800


pop the seat, and unscrew the two screws you see at the base of the tank. Slowly lift up and pull towards the rear of the bike, the tank will pop up enough so you can pull the wire and thenuse a deep well socket on the plug. Do one then rotate tank the other direction and do the samething for the other
