Question about 2001 Triumph Legend TT

1 Answer

Smokey exhaust When I fire the Legend up in the morning (on Choke) the R/h exhaust emits noticeable exhaust fumes - enuf to be noticeable, albeit not like an E-boat be honest I would not even have thought about it as being unusual - except that you can't see any exhaust fumes from the L/h exhaust! (I usually have a ciggy whilst the bike warms up a bit / I drop the choke down - so have time to notice these things ). I had noticed it before it started getting a bit colder here in the mornings - but certainly now looks more pronounced due to the chill.....I am sure (hope!) their is a logical explanation........

Nothing to worry about. On mine, I can really see the difference when the temperature is below 20 degrees (F). There is a ton of water vapor coming out of the right hand exhaust but only a little bit from the left.

I believe I burnt a exhaust valve on my Harley missing real bad stinks of gas exhaust fumes and exhaust is a lot louder

Richard, the next step is t do a compression test on both cylinders.
Much more likely that you have a spark plug fouled or not firing...

Triumph Legend 1998 same as Thunderbird 900motorcycle running badly.

Was the bike working okay after the overhaul? Mis firing due to bad setup or very bad fuel.If it has not run right since the work was carried out ask the repairer to take a look.
If it only started to go awry after using wheap fuel, (it should still be of uniform quality with other fuel,)
I would drain the tank and refill with premium. Try not to get any air into the system if you do this, makes life easier

Starting problem wont start on choke

You need to explain a little better... do you mean it will only crank properly when the choke is open and the throttle is closed ??? Has the battery been properly charged and tested ??? ( be honest here because we can't help if you don't ) are the battery cable connections is good shape ??? Have you tried spraying some carb cleaner into carbs when cranking ??? I have the same engine on my Triumph

NSR 250 timing

Just a hunch. Clearly there is a fuel issue on one of the cylinders. Although you cleaned the carb, please confirm that the intake valve is clean and/or reed valves are working properly. It is possible that the 2nd cylinder is only firing occasionally even at the higher RPM but it's less noticeable because of the engine's inertia at that speed makes it "seem" to be running smoother. The clue lies in the fact that the engine runs smoothly at idle when the choke is applied and starts to miss when choke is open ... this is indicative of fuel starvation. And yes, on a 2 cycle, a lack of fuel means a lack of lubrication.

Out of curiosity, take both spark plugs out and crank the engine. Do this outside away from an open flame. Compare the amount of misted fuel that comes out of each cylinder head with the choke closed and then again with the choke open. If it isn't even then the cylinder that is blowing less fuel is being starved. This should identify the problem cylinder and help to narrow down the elements left to troubleshoot and replace/repair/clean. Good luck and hope this helps

My 2003 yamaha yz450f will back fire the whole time when i stop giving gas, with choke on or off and if i put choke off it dies

there may be a problem with the exhaust valves first check and adjust the clearances,

another reason can be leaking inlet or exhaust gaskets

2006 TTR250. Bike will not idle unless choke is fully engaged. After a minute or less of this the head pipe (the one that comes right off the block, I don't know if I have the name right) becomes glowing...

two things you have to oberved. Choke is only applicable if you experience hard starting in the morning,If yes then use choke for a while till you got your motor idling stage.the glowing red hot indicates that your engine is flaming hot, this means your choke is steadily on.( never stay your choke steadily on.).Try to clean your carb , carb cleaner will do. even without dismantling your carb from the engine manifold.Rev your throttle and spray through the air intake, you'll notice a foul sound bcoz the cleaner is mixing with your gas,it's fine.also you'll notice a black smoke while doing a full rev. it's also fine , thats the carbon that need to push out from your carb. take it from there my friend ...let me know the result.observed your bike

I want to change my motor oil which is the drain plug, i smell exhaust fumes untill the motor warms up?2000 ultra clasic

The oil tank is on the bottom of the transmission. There are two drain plugs. The drain located about the center of the oil pan is the transmission drain plug. The drain plug nearest the front left of the oil pan is the engine oil drain.

A rich smell to the exhaust fumes when the engine is cold is typical. The computer on your bike (and your car) senses that the engine is cold and requires a slightly rich mixture to run. When the engine warms up, the computer leans the mixture back out. This is why you don't have a "choke" on your bike, the computer changes the injector dwell time to richen the mixture instead of you having to use a choke.

2003 honda vtx1300 back fires when cold or hot choke open or not

hello and welcome
backfiring is common associated with a lean condition. if the bike has a stock exhaust and air cleaner setup. most likely the pilot jet or main or both jets may have developed a builup. this is very very common. for this will produce the lean condition and cause popping. you may notice this more on decelleration. if slightly holding open the choke helps this a little bit. that will verify the lean condition. the carb float bowl should be removed and the jets removed and cleaned thoroughly.
if this bike does have aftermarket exhaust it is a good possibility that the jetting needs to be adjusted richer for the lean condition that the exhaust causes. thank you.
