I have a 2002 honda vtx 1800 will not idle but loads with gas
Bike began to run excessivly rich,ask honda mechanic about problem.he said i didn't ride the bike enough becausee it has only 3000 miles on it.and that the fuel injectors were gravity leaking.so i replaced both injectors.replaced plugs and bike still runs rich on the low end and loads with gas until it dies,
do you have any ideas ?

Check for a blocked airbox vent, sometime we put things under the seat that will cover the airbox inlet which will automatically make the bike run extremely rich and all that needs to be done is to remove the paper or gloves or whatever there is blocking the inlet snorkel. You may also want to check for tight intake valves too. That is classic Honda, tight valves will cause a rich mixture all the time if it is the intake valves making the problem. Please let me know if this works, if not give me more specific data and I will better assist you.

The Honda VTX 1800 cruiser boasts a monstrous 1,795cc
liquid-cooled V-twin engine, with three valves per cylinder and a
nine-to-one compression ratio. It has a bore and stroke of 101 by 112
mm, making it an undersquare, or long-stroke motor, meaning it's tuned
for low-end torque. With a curb weight of 800 pounds, you'll need all
that low-RPM power to get off the line. The bike does not have a
tachometer, so you'll have to shift the five-speed transmission by feel.
The bike is fuel injected, with an automatic choke. Fuel
injection helps the VTX 1800 ride more smoothly than carbureted V-twins.
The tank carries 5.3 gallons of fuel. In reviews, the bike had an
average range of 194 miles on a tank of gas.
Performance and Handling
This is a massive and massively powerful motorcycle. It
corners wide, and is really meant for highway cruises rather than city
riding. The bike gets a remarkable 100 foot-pounds of torque at 3,000
RPM. The suspension is rough, and you will certainly feel bumps in the
road. Honda, however, has put a lot of effort into minimizing engine
vibration, so the gigantic V-twin won't rattle your bones the way you
expect it to. The engine makes a solid, satisfying thump without
chattering your teeth.
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.
Your fuel petcock is in the rear of the tank. At steep downhill angles all the fuel flows to the front of the tank and not in the petcock. Meaning at steep downhill angles with low fuel level . . .your bike doesn't get any fuel.
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.
Your carb idle pins/needle valves are either fouled or worn/damaged. Or floats that control your equilibrium for gas distribution throughout the carb array are not working together with valves/pins. Has this bike set a spell, at least once for too long of an interval? I'd pull the whole darn carb setup and inspect/clean, then reinstall exactly to specs. Ask for the very best teardown/rebuild cleaner for carbs at the parts store! Betcha a little elbow grease and a perfect dismantle and clean, then rebuild is all you need! Been there----Did dat!
