Anyone have ideas on fix for these problems?

1) My bike at idle is anywhere between 1020 and 1250 rpm, and is constantly hunting up & down.
2) At any constant rpm, the is a very slight miss at irregular intervals. It is anywhere from every second to 3-4 per second, with no regularity. It's very slight. Not noticeable on accel or decel. Don't know if it's so slight that it's impercentable, or it's not there on accel and decel.

Any ideas?
On number 2, my idea is a coil going bad. Number 1, I don't have a clue.

The reason for asking is that the bike is under warranty, and been in the same Triumph dealer 4 times for these issues, and nothing has changed. But, they put on a new chain at 2500 miles, which had no effect. I might add that each time I drop off or pick up the bike is a 150 mile round trip. So, I need some ideas on these problems.
Thanks in advance.

What year, mileage, mods (airbox, exhaust), tune #?

This info may be valuable for help.

I wouldn't call myself an expert on the matter, but isn't the K & N filter designed to allow an increased air intake into the engine? Isn't this mod supposed to be carried out only in conjunction with ECU-tune/exhaust mods?

Also; 2900 miles in two years would indicate that the bike hasn't been used 23 out of 24 month of its life. Could these problems have been caused by old petrol leaving the usual slimy goo inside the fuel pump and/or fuel injectors?

Lacking as yet any better suggestions of someone more informed than me, how about:

- replace the K & N filter for the stock filter.
- if that doesn't help (and the tank being removed already anyway), remove the fuel injectors and clean them in an ultrasound bath (any optometrist and most wearers of glasses have one of them). NOTE: use new o-ring seals on refitting the injectors.

I once got a dirt-contaminated tank-load of petrol in the French hinterland that caused exactly the same problems that you are now having. In my case the injectors were badly clogged with that dirt and the ultrasound cleaning did the trick. In your case the "dirt" might just be the goo forming if old petrol is left for too long a time in a carb or fuel injection system.

Hi, It’s not very common for a coils to fail on a 1050 so early from new,
Not sure if you bought the bike with the concern you have mentioned, or if this a problem that’s just started to develop,

Miss-firing symptoms with spark plugs and ignition coils are sometimes noticeable under engine load, but you state it’s not noticeable when accelerating,

I would try the simple opinion first,

Try a force adaption to see if it helps,
1. Ensure the coolant is at ambient temperature
2. Start the engine and allow it to warm WITHOUT TOUCHING THE THROTTLE until the cooling fan comes on.
3. Leave the engine to idle for a further 12 minutes.

Job done, may take a few runs with stop starts to smooth the bike out afterwards,

Hope this helps,

Thanks for the replies.
Tried the adaption, no change.
Bike is one year old from new. Left over model.
Have been using different brands of fuel, all 93 octane, no change.
Stock air filter, no change.
Added +6% on the fuel map, no change.
Had it in the Spring Hill Triumph dealer for 8 days. Said they changed the map sensor and it was fixed. (I believe they didn't do anything). No change. Previously they said it was the chain that had a tight spot. (***?) Replaced chain under warranty. No change.
Added full bottle of Seafoam to tank of gas. No change.
It is slowly getting more pronounced. Trying to get it to a point of obvious need of repair to take it to different dealer. The bike is under warranty for 9 more months, so I would rather Triumph fix it, if it is their responsibility.
Just checked front sprocket and it appears to be tight.

i agree with you remap, it suggests a lean condition at idle/off idle.
the 6% did nothing? did you try a little more?

Yea, Iscoot, I tried 7% and there wasn't a noticable change. Haven't been riding the Tiger much lately until yesterday. Last 2 days I have put 130 miles on it and the problem is getting worse as miles pile up. After a few hundred more, I will take it to a different Triumph dealer.

Hi, I think trying to richen the fuel mixture is only trying to mask a problem and not fix it,
You need to find out what’s causing the fault,

If your bike is still under warranty then you should find a good dealer to find and fix the problem,
If not, and you have you have Tuneecu, I would start by checking if the Idle speed control valve voltages are within the + or – range, and also check if the throttle bodies are in balance,
These checks are usually for much higher mileage Tigers,

Instructionson the link below;-- I would only use this to check only if bike is under warranty ---

These checks are usually for much higher mileage Tigers,
Good Luck
