20 Most Recent 2004 Triumph Triumph Bonneville Questions & Answers

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. http://www.bikebandit.com/aftermarket-parts/motorcycle-fuel-and-air/2004-triumph-bonneville-t100-carb-kits-parts-accessories-universal/pb9?m=147325&f=3

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

better chec complete wire system for flaws-titen all screws n look for corrosion

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?

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.

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.

First of all, why would you? Where are the keys? Are you the owner? What make and model?

Yes they are plugged if they have any ethanol fuel in the fuel system and the fuel system had no stabilizer added. The fuel system will need cleaning

Under the seat

It could be worn rings ( especially if it is an older t120 60's-70's ) that is allowing compression into the crankcase and blowing the oil out the breather.
