20 Most Recent 2004 Triumph Triumph Bonneville Questions & Answers


Hi, Gregory love that first name, and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
6. A faulty ignition coil or electronic control module.
7. Faulty pulse coil.
8. Faulty CKP, CMP, or BAS sensor.
9. Faulty ignition switch.
10. Faulty run/off switch
11. Tilt sensor needs a reset.
12. Security alarm failing to disarm needs reset

Here is a link to a bike parts outfit that I have had good luck with. This link should take you directly to the Carb kits you can get. These are the things you need to do a partial or complete rebuild. It's sometimes better to replace with new, as they are cheap, as long as you are tearing it apart to clean.

I had an 05 Bonneville and it had carbys, so has your 04 model. Fuel injected Bonneville came out a few years after this.

Water is getting into your ignition coils.
Trace the spark plug lead up to the coil.
Get some ignition sealer spray and spray loads of it on the leads and coil.
When a bike is new, it is sealed. After washing with detergents it gets washed away. Spray the leads and coil once a week to keep them totally dry.
An immediate way to get round when wet is to spray wd40 on the leads and coil, it should start straight away.
But, don`t spray ignition sealer on until it is totally dry.
Hope this helps

depends on what and where you are measuring ... if you are measuring rpm of the crank shaft ... there should be no change baced on different drive sprockets. The speedo will be different and the RPM will not match the expected speed because you changed the size of the drive and driven sprockets.

Chances are the carb slides are out of synchronization. Remove the air filters and look inside the carbs ( with a mirror if need be ). With engine off, crack the throttle and see which slide begins to raise first. Adjust the other carburetors' cable to make the slow carb raise to match the timing of the other carb.
Put in some new spark plus as well.

fuel filter or fuel restrected.a line bent or cloged or the screen it tank?

2004 Triumph... | Answered on May 28, 2009


Your bike's alternator probably isn't recharging the battery. You can check output yourself if you have a VOM or have a shop test it.

2004 Triumph... | Answered on May 11, 2009


Probably a loose or dirty connection in the wiring. Pull the gas tank and check all connections including the spark plug connection. You may want to put a more waterproof spark plug cap on the bike. If you can find it, get a can of LPS 1 and spray all wire connections, ignition coil and even inside the flywheel.

LPS1 is a di-electric. It will not harm electrics. Sprayed on ignition points, you can run a water hose on them while the motor is running and it won't miss a beat. I didn't believe it so I tried it. Works great! Google ' LPS lubricants ' for a source. Yes, I know it says lubricants. It is a di-electric lubricant. Try it.

Please rate this solution. Thanks!

Hello
Sounds like a lean fuel problem
i would check the fuel content and see if you have a plugged fuel lo\ine.

Hi, Bobhamilt790 if you have changed your engine size, compression ratio, fuel delivery system, air filter size or flow rate, mufflers or exhaust system or a significant change in altitude your carburetors need re-tuning and if your fuel system (gas tank, filters, fuel valve, and carburetor) is contaminated with ethanol sludge, varnish, rust, dirt, water, etc. or your bike has been sitting for months or years without running these components must be "PROPERLY" cleaned and reassembled "CORRECTLY" before any adjustments can be made. Tuning your carburetor is fairly simple once you understand the basic principals. Your engine is a simple airbox sucking air in and blowing it out, it is finely tuned at the factory for maximum performance once you upset that delicate balance by changing air filters, camshafts or exhaust systems your performance may go down the and the engine may run poorly, you need to compensate the air-fuel mixture in the carburetor in order for the engine to run smoothly and at peak performance. If you are running multi carburetors you need to sync them first and make sure your air cleaner element is clean and dry for paper elements or lightly oiled for foam and meshed elements and properly installed. Here is how and where you compensate trouble: "TIP" if your engine "BOGS" you're not getting enough fuel.
1. Close to 1/8 throttle is managed by the air screw and pilot/slow jet.
2. 1/8 to 1/4 throttle is managed by the air-screw, pilot/slow jet, and throttle slide.
3. 1/4 to 1/2 throttle is managed by the throttle slide and jet needle.
4. 1/2 to 3/4 throttle is managed by the jet needle, needle jet, main jet, and air jet.
5. 3/4 to wide open throttle is managed by the main jet and air jet.
6. A wide open throttle is managed by the main jet.
If you are running lean, spark plug electrode color is white, the engine runs hot and feels like it is starving for fuel you need to go up on the jet size or move the c-clip down one notch. If you are running rich, spark plug color is black or dark grey, the engine runs cool, and bogs down when accelerating you need to go down on jet size or move the c-clip up one notch. When your carburetor is properly tuned for maximum performance your spark plug electrode will be a light tan color like coffee with cream. If you prefer fuel economy over performance you can go down on main jet sizes until a satisfactory level of lower performance is acceptable versus MPH, your spark plug color will be whiter and your engine will run warmer. These tuning adjustments will only make improvements if your intake and exhaust system have no air leaks or sealing issues and the entire electrical system is in proper working order and you have no mechanical issues.
