These bikes do not have caburettors as they are fuel injected. or an oil tank....the oil goes directly via a screw in plug into the sump.
I am not sure by what you mean about having a fire in the exhaust.

    • 1 Clean the underside of the motor with soap and water to remove any dirt and oil build-up that could contaminate the motor.
    • 2 Warm your motorcycle to operating temperature by starting the motor and letting the oil warm up or by taking a short ride. The oil will expand slightly and flow better to give you a more accurate reading.
    • 3 Park the motorcycle on a level surface and turn the ignition switch to the "Off" position. Place your Triumph on its center stand, if equipped with one, to provide additional stability.
    • 4 Place your catch basin directly below the oil drain plug on the underside of the motor and remove the drain plug with the appropriately-sized socket. Allow the oil to drain until the flow has reduced to a thin trickle then replace the drain plug.
    • 5 Locate the oil sump drain plug and center your catch basin below it. Remove the drain plug and allow the oil to drain until the flow is reduced to a thin trickle then replace the drain plug. Replace the drain plug. Note that this step is only required on certain models, such as the Thunderbird Sport and older "oil-in-frame" models.
    • 6 Remove the oil filter with an oil filter wrench and discard the old filter.
    • 7 Fill the new oil filter with fresh oil, coating the inner lip of the filter lightly with oil to provide a stronger seal before screwing the filter onto the motor. Tighten the filter by hand until it is secure.
    • 8 Add your engine oil into the oil tank. Replace the cover and wipe away any spilled oil.
    • 9 Locate the engine sump bolt, located at the base of the cylinders and the carburetors. Remove the bolt and add half a quart of oil into the sump. Replace the bolt and wipe away any spilled oil. Note that this step is only required on older "oil-in-frame" models.

SOURCE: tiger triumph 2008 brand new wont start... help

you have a problem with the starter not turning the engine. so we probily not sending a signal to the starter.
you realy confused me when you started talking about gas and choke?
if the engine doesnt turn over none of this even matters.

these new bikes have many safety features .
you have a sensor for netural and you have a sensor for your kickstand and a sensor for your clutch
and all of these have to be workinf right for your engine to turn over.
so with your kickstand up and the bike in netural and the clutch lever pulled in
it should turn over and start.
when it doesnt you need to check your wiring to the switches one might have come loose.
or could be a bad switch.
let us know what you find

SOURCE: My 2006 Triumph America has a problem starting.

I have a friend that has a 2006 Triumph America and the same thing happened to him. Started running on one cylinder and then just refused to start. I did a check on everything and found that the CDI went bad. This is mounted under the fuel tank along the back bone and is about 3 inch square box.
They mounted them with a type of plastic rivet and would vibrated on the mount and cause something inside to break. When you replace it mount it solid and use a piece of rubber between the mounting plate and the CDI.

SOURCE: bike is back firing and has a hard time

Sounds like the carbs need to be synchronized. What you have with a multi carb bike is a multiple small engines attached to the same crankshaft. If one is accelerating harder than the others, it will cause "cylinder fight" as the others either fight to keep up, or slow the faster one down. You need a special tool to do it, or you can get it done reasonably cheap at almost any bike shop. It could also just be a spark plug wire shorting out. And make sure they are in the right order. Good luck.

SOURCE: Are the 12/2007 and 2008 Triumph T100 the same

Then 10th digit in the vin number tells you the year.
If it is a W = 1998
X = 1999
Y = 2000
If it is a 1 = 2001
2 = 2002
So your 12/07 bike is a 2008 and the 10th digit in your vin # will be an 8

Screaching fuel pump! triumph america 865

Ok check your fuel filter first,then check fuel supply, If fuel is restricted the fuel pump will starve for fuel. You should check fuel pressure at intake. It does not sound like a fuel problem. Also does it happen at idle or under acceleration.

2009 triumph thruxton still popping even with power commander installed with d&d exhaust

Yes. take it to a Triumph dealer and get them to install the correct ECU map. They are very good at helping in this way. You didn't really need a power commander as Triumph fit a reprogrammable ECU for just this reason.
