Triumph Tiger 800

[Shep]

Took my Road model out for its first proper ride today, about 200 miles of mostly local backroads in the sweltering Midwest head and humidity. Coming from a 1200GS, I am very happy so far. Heading to Louisville in the morning to have the shop mount the Arrow slip on. I have them on my Street Triple and knew I wanted it on the Tiger as well.

Right as mine turned 2000 miles it was hit by the stalling problem.

What octane gas is everyone using with the stalling issue?

I'm sorry, but Welcome to The Club!!!

I've been running 87 this past weekend. And coincidentally, this weekend is when my stalling started. It's not really related to 87 in my opinion. Last month, before I took mine in to the shop, where it stayed for 25 days and got a new throttle body assembly, I was running both 91 and 87. No issues with stalling before I took it in for its 500 mile service. Just a 2000 rpm idle. ..

I've been using 87 octane gasoline exclusively. I don't know if it matters, but my stalling also started sometime after the 500 mile service.

Many of the GS guys just yanked the canister. End of problem
But since the Tiger stalling is world wide the canister most likely isn't the problem. Well except maybe the rider who stalled running through deep water.

I think I'm the lucky rider that stalled in the stream crossing that you're referring to? Anyway, the water was not that deep. It was however deeper than the canister on my XC. I'm convinced that it choked and died in the water because the water got sucked up through the tube with the right angle bend in the photo below.



So, the location of the charcoal canister on the Tiger 800 is right below the gear shift lever.

Always using premium, which ranges between 91-93.

You may have a point. That vent is very low.
It's my understanding that vent serves as a air intake to equalize negative pressure in the fuel tank caused by the fuel pump. If water temporarily blocked it, maybe a sensor that controls the system sent an error message to the computer..

Does seem a bad place to mount a canister on a dual purpose bike. The BMW one is up around the cylinder heads.

You could test it by starting the bike then blocking off the vent

Disclaimer: I'm just speculating, I really don't know much about this technical stuff..

Me, I would reroute that hose intake up ......... and I'm noting this as well, for when I do buy one .....

And my dislclaimer: I too, know really nothing about this stuff .....

G-

I know the same. I'm thinking that right angle hose is an overflow. Meant to drain the canister when/ if it fills up w/ whatever it fills up with. I hope Triumph figures out all this stalling, idling, poor running bullshit by the time you are ready to buy one. If not, don't buy one yet.

I'm totally frustrated with my bike. Want a replacement or refund and told the Customer Relations Manager at Triumph so. He's not responded since...

I'm gonna try the test- blocking it off while running- in a bit....

Use a T piece to route another hose high up because that thing might also be an overflow ...

A simple check valve would prevent backflow, but since the majority of the people having the issue are having it without fording a river I would say you are chasing ghosts if you focus on the canister. This at least is easy to test. Stick the tube in a cup of water while it is running to see if it sucks it in

Brilliant!!

If the Tiger is indeed in closed loop mode at idle, I would try to disconnect the O2 sensor and see if that makes a difference.

This should force the bike to operate in open loop mode all the time which is no big deal.

When engine breaking on the Tiger, there is a lot of noise coming from the cat. This is unburned fuel igniting as it hits the very hot cat. Maybe the computer is reacting to all that excess fuel in the exhaust and leaning the bike out causing it to stall. It starts again when the throttle is opened a tad because the ECU sees that the throttle is no longer in the idle position and moves to a section of the map that is open loop.

Just a thought.
