Question about 2004 Honda VTX 1800

1 Answer

I checked the valves on a 2003 Honda VTX 1800 fuel injected model. The valves seemed to be a little tight, escpecially the exhaust valves. They were adjusted using the recommended feeler gauges for intake / exhaust. Everything went well with the valve adjustment. Bike was started, idled for four minutes and driven about two miles when it died. Now the bike won't start. It seems during starting when the starter is turning the motor, it slows and then basically stops the starter motor from turning. Valves were rechecked and everything looks good. The plugs are new and have lots of spark and there is fuel on them when pulled. It seems like the timing is off, but I don't know how that happened with a valve adjustment. Any ideas?

Hello, my 2004 Honda VTX 1800 after heats up on low speed the engine shuts down. What it could be?

Hi, Martynas and the usual suspects are:
1. Engine oil level and SAE weight are too low or not circulating.
2. Insufficient or blocked air flow over the engine.
3. Heavy combustion chamber carbon deposits.
4. Ignition timing retarded due to faulty MAP, CKP, or CMP sensor.
5. Carburetor jetted too lean.
6. Leaking intake or exhaust valve.
7. Water coolant old or low change every two years.
8. Water pump failure.
9. Radiator clogged, cap loose or malfunctioning.
10. Radiator fans not coming on.
11. Clutch slipping, brakes dragging, heavy load, towing a trailer etc.
12. Idling too long without moving.
13. For constant hot weather temperatures, mountain, or desert riding conditions consider adding an oil cooler and or cylinder head cooler.

How do I check the fuel filter on a 2006 honda vtx 1800

  1. Engine
    • 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.
    Fuel System
    • 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.

Fuel injection..Hard to start will not idle and pouring gas out the exhaust.2003 vtx

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.

How do u adjust the idle on a fuel injected vtx 1800 honda

should be an adjuster between the cylinders. Looks like a threaded knob. Sometimes you have to pull it out a little first.

2003 Honda VTX keeps blowing the fuel fuse when I make a sharp left or right hand turn or his a good bump in the road. What is causing this to happen

You have a short circuiting cable that are hitting or touching a metal part. Check all your wiring cables.
Good enough?

I have a 2002 honda vtx 1800 will not idle but loads with gas

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.
