My 2002 VTX 1800 has a problem. It does not run

more than likely its in the gas tank

Sounds like you have bad gas/ a bad fuel filter. I know on the VTX1800 models the fuel filter is located just ahead of the fuel pump inside of the tank, If the bike has been sitting for awhile the gas is bad. I would make sure that you have a fresh tank of fuel in it for starters and you might need to replace the fuel filter. First try putting fresh gas in it and letting it run through the system. Let me know how this works, jeff from fixya

if this is a vtx 1800 then you need to look at the fuel pressure regulator, this is faulty and sending fuel up the vacuum hose, they are around £40 to buy and about an hour to fit. they play up any time from 6000miles,even know to one 2000 miles but was changed on warranty.

Have you changed the oil lately? If there is to much oil in the motor the bike will push oil up into the airbox and foul the air filter out. This will cause the bike to run rich. check the oil level and then drain any excess out to the proper level. You will need to clean or replace the air filter in order to make the bike run well.

sound like you just running low on fuel you probably dont have a problem at all don't let you fuel level run so low if it does that turn your fuel petcock to reserve and head for the nearest gas station.

Should be a bolt at the rear of the seat ...

You could use some carb cleaning and sychronizing.

You have electronic fuel injection. The fuel pump may not be working. Check all the fuses and wire connections. Also clean the air filter.

go ahead and run a full tank of 93 octain gas through it and when you get a chance open it up in each gear, it will clean what ever is in it out.
