Question about Triumph Thunderbird Sport Motorcycles

Open Question

On my 2000 Triumph Thunderbird Sport, I recently changed my fuel filter and main fuel line into the carbs. After about 10 minutes of riding, the bike suddenly lost power and the exhaust note became very flat and thuddy sounding. In changing the main fuel line, I removed the fuel tank and disconnected the wiring harnesses for the spark plugs that are fastened to the motorcycle frame under the fuel tank. I double checked everything after I cut short my ride and everything seems to be connected right. I checked everything else out...no fuel leaks, no disconnected air hoses, etc...I had also recently done an oil change, put in a K&N air filter, and changed the spark plugs. The bike was running fine after that. Any assistance you can provide will be greatly appreciated. Thank you, Brian Colebaugh

sounds like the throttle cables need to be looked over .( he get everything back to where it was before the lubing?)as one may be out of sync with the other. the oil change has NOTHING to do with the sputtering and surging ,stall .it would only apply if the clutch was slipping and that would make the bike rev with the car oil.

SOURCE: Air box and crank case fuel flooding problem

Well there only one way the fuel can get into the crankcase and that's from the fuel tank. The petcock must be draining and the float needles are not stopping the fuel flow. Do you have a prime position on the petcock? If so do not run the bike in the position. Try topping the tank off with gas and letting it sit for a while and see is the gas has gone down and then check the crankcase and see if there's fuel in it again. i still say its got to be your petcock.

Check fuel filter and air filter, then spark plugs, not necessarily in that order.

SOURCE: fasten car stereo to motorcycle

Hi
Ive seen many different ways of attaching stereos to bikes, the most successful of these were hidden from view & therefore difficult to access (to change discs etc). Most of the others were the cause of various types of damage to the bike, inflicted by opportunist thieves who fancy an easy steal (no car to break into!!)
Depending on the size of your units, the player may well fit under the rear panel (tail light housing) & the speakers will fit in the panniers. This will ensure that extra wiring is kept to a minimum; small holes can be drilled in the sides of the rear panel & the back of the panniers, for wires to the speakers
The speakers can be fitted to the inside of the drop-down lids or high inside the back of the panniers.
This would be mainly for entertainment when parked up.
For music on the move an MP3 player would be better, this could fit into any pocket or a docking bracket on the handlebars, sending music to your headphones via bluetooth.
With high end systems 'direct ipod control' gives you the power to control your ipod from your head unit or visa versa, JVC KDR models can also be controlled by an iphone, have a remote control unit included & detachable fascias

Ride safe

Please mark this as very helpful (if it has been!!)

I can start my bike up, with full choke on, but after a few minutes it will die. Also, whenever I give it gas with the throttle, it immediately dies.


Something has to be fubar with the main jet circuit of carb. That explains why it starts and then shortly thereafter shuts down. Also explains why when you give it gas it cuts out cold.

U have ignition but NO engine will run without proper fuel flow.

2001 Triumph Legend TT engine oil flooding with petrol


Hi, Malcolm you're getting ready to go riding you pull out the dipstick to check your oil level and are greeted with the unmistakable smell of gasoline. What happens next depends on the following:
1. You have experienced this before and do not start the engine but do change your oil and filter leaving it 1 quart low until the engine reaches operating temperature then top off as necessary.
2. The amount of time your bike has been sitting since the last time the engine was running.
3. The amount of gas and contaminants in the tank.
4. The oil pump location, exterior or interior.
5. The condition of your petcock gasket/seal/diaphragm.
If your gas tank was low and you start the engine probably nothing you would notice but if your gas tank was full and you start your engine the oil/gas mixture can blow into your air filter, come streaming out of your crankcase breather hose, and launch your oil tank cap followed by a blast of oil. The mess can be minor or you need to call a Hazmat team for assistance. This will also happen if you overfill your oil tank.
Next is the how and why gas can get into your oil tank/system:
a. The vacuum petcock rubber/diaphragm fails, which allows gas to flow from the fuel tank through the petcock, through the vacuum line into the intake manifold, then into the combustion chamber, where it seeps past the piston rings and into the bottom end.
3. Nonvacuum petcocks that are not turned to the off position will patiently wait until contaminants from the gas tank build up in between the carburetor needle and seat breaking the seal thus inviting gas to enter the combustion chamber eventually finding it's way into the bottom end and the oil tank.
4. Bottom line if you're not going to ride your bike for a while turn off the petcock.

I have a 2000 Triumph Thunderbird with low miles. The last time I ran it was in Jan 2010. I turned fuel switch to on and fuel started running out. I turned off and stream stopped. I turned it on again...


I assume that this bike is carburetted. Most likely the float needle in the carburetor, (or carburetors if equipped with more than one carb), stuck when you first turned on the gas. If the gas has stopped flowing when you open the petcock, you should be OK to start it. If the problem persists, you will probably have to pull down and clean out the carb(s). Pay special attention to the needle and seat. Make sure the needle has no corrosion present, You can use Scotch-bright to clean needle and seat.

Bike sputters with no throtle when trying to start. If any throtle or choke is used bike will not sputter at all. If starting fluid is used bike will start. I've changed plugs ,new gas and cleaned air...


Hi
Check/replace inline fuel filter. Put a fuel injector/carb cleaner fluid in the tank and run it through, this will clean any build up that may be in carbs/injectors.
If problem is still persisting then you'll need to get carbs/injectors removed for cleaning and resetting. Hope this helps, let me know how you get on.

Leaking fuel from carberator overboard drain


the float is stuck in the open position, this is common after sitting for a period of time. You will have to remove the carb and clean it out.

Broken throttle cable


This may be a real hard job. You will have to remove the fuel tank, If your bike has a large air box under the tank you will have to remove it. Now you should be able to see any cables to the carbs and any clips or brackets that hold them in place. You may have to remove the carb's also - reason will be to gain access to the cable ends, they have a ball that fits into a slot on the carb linkage and can be very tight or hard to reach. First things things first, disconnect the battery. Hope this helps you get started.

Engine cuts out


It sounds like something is preventing the bike from getting fuel. Check fuel filter, fuel tank vent, air filter too. If you have vacuum building up in the tank, letting the bike sit for a few minutes slowly releases that vacuum allowing the pump to pull fuel easily again for a bit. Next time the bike quits open your fuel tank. If you hear a whoosh of air being sucked in look for a plugged vent line. A plugged air filter can have a similar effect but the only way to check that is change the air filter or look at the one you have. It would have to be really, really dirty or plugged with some debris to cause this problem.
