Is ok for an oil to change his colour after changing, but depends in how many miles. There are a couple of causes for that. Keep in mind that you can't drain totally the old oil from an engine and that way your new oil will receive some black colour from the old one. Also, the oil is going to the cylinders where are extreme temperatures and residues. Maybe you had a to used oil in the engine or a bad one and you have deposits inside and the new oil washed those and received some black colour from them. Next time before adding some new oil use a motor flush to clean it, but be carrefully when chosing it.

What settings?Points?Plugs?Clutch push rod?Clutch pressure plate?Clutch cable?Valves?Brake cables?Throttle cables?Primary chain?Rear drive chain?Also, a MODEL YEAR would help!

Look underneath on the bottom of the sump and you will see a plug with an allen key socket.To remove the filter is very difficult without the correct triumph tool.(T3880313)

Sounds like your battery is dead.

Which model triumph have you got please?

Most likely cause is the battery. The other problem could be in the charging system.Start the bike and measure the voltage at the battery with the battery fully charged (charged the battery with a trickle charger like battery tender)Should read in the 14 v or higher range. If it doesn't the problem is probably the stator or voltage regulator.

Ok not much to go on but is it in neutral? go check. I spent a day trouble shooting because I left it in gear. On a Triumph Sprint you need to pull the clutch in also.

Your Sprint has no choke as its injected and fuel is controlled by the ECM. So this said there are a few possible things to check.1 TPS throttle position sensor voltage.2 Barametric pressure sensor (MAP)3 Do you use fuel containing ethanol, injected bikes hate the stuff, makes them hard to start. Number 3 is an easy thing to try, 1 and 2 you will need to look at the ECM with a computer. Its very easy and the cable to connect to your laptop is about $14. OBD2 to USB cable.

sounds like valves

Problem is that you have got blocked breather on tank causing a vacuum stopping the flow either drain some fuel off or have the bike running without cap on

Sounds like something has clogged one of the pilot jets in the carburators. You can figure out which one by feeling which pipe is cold after running for a short time. Probably best to clean all 3 carbs while you have them off.

Left side is #1, Right side is #3.The firing order is 1,2,3.

SOunds most likely to be a connecting rod lower end bearing.

With a fault like this it could be a failing coil, a blocked fuel filter or a failing fuel pump. Try the fuel filter first as it is the easiest to replace.

the wiring is probs stuffed

possibly a loose connection, or bad ignition component. sometimes they are hard to diagnose without actually listening to the problem.popping at high RPM would indicate a valve spring problem, or lean mixture. popping at low RPM could be a lean problem also.

Do you have power on the bike, do the lights work, horn work, does the battery have a good charge.

check oil level,, sounds like you need to set cam gaps/tappets.

Try the fingers from a marigold glove. cut them off and use them to protect the plugs and caps.
