I just got this 06 Sprint and it has the TOR silencer and I have verified at the Triumph dealer that it has been remapped for it.
Is it common for these bikes to run rich?
First of all, I can smell it, secondly when I rev it, a cloud of black smoke blasts out the back like 3 cannons.
It does it when I gun it going down the road too.
I'm thinking of bringing it in for a checkup but I wanted to find out if it was a common thing before. I havent checked the fuel mileage yet. I've just been riding it without paying attention to it.
I will check that in the next day or two.

Check your fuel mileage as soon as you can. There are things that can go wrong (Rarely) that would cause an over rich mixture, leading to ring failure. Check out the clocks computer, it displays average fuel mileage ..

Why will running rich cause ring failure? I've seen plenty of valve, piston top, land and broken rings running lean but never ring failure running rich.

If the SAI solenoid fails, air is permanently drawn into the exhaust, the lamda sensor sees a very weak mixture and tries to adjust the mixture to compensate. Fortunately the lamba sensor is only used in closed loop control at idle on the 2005-2007 (8?) Bikes, but I believe it's used on more than idle settings on the later models. Far too much fuel washes the bores, wearing out the rings. It tends to be the centre pot that loses compression first. It is rare, but been at least two I've read about on the boards. Reports that the Bikes get more and more difficult to start. Compression tests showed the centre pot with practically no reading. One of these Triumph did an out of warranty repair at their expense with the express instruction that the person concerned wasn't to post about the SAI Failure (it didn't flag a yellow engine management light either)

Ouch.
I will know what the mileage is tomorrow.
My fuel light came on on the way home from work.

If there is anything wrong with this bike, its as good as gone.....or salvage motor....

Just had a thought, the TOR tune needs to be the right one for your Bike. If you upload a non SAI (Secondary Air injection) Map to the ECU it leaves the SAI fully open all the time. You can run a non SAI tune, but you need to blank off the SAI solenoid.

I had to read up on what the heck you were talking about.

Now I understand.
For a U.S. sprint 1050 with the TOR can, you would need the 20106 (aftermarket pipe WITH secondary air injection) This is good info.
I will bring it back to the dealer and ask which tune exactly is on it.
My question though is why would a US dealer have the ability to disable emissions controls such as this anyway?

I'm not an expert on the 1050s, but I think the SAI is still a Cali thing on an '06. My '04 is definitely an SAI-free 49 state model, as was my '96 Trident.

Emissions control regulation vary from Country to Country, so Triumph taylor their models to each market. Hence if someone picked the TOR map without SAI and accidentally installed it on an SAI Bike it would cause problems. Capping off the SAI and using a non SAI map reduces the popping and banging on the overrun to a minimum. Personally I like the noise. In the UK Triumph have to supply the Bike with SAI to meet UK(EU) Emissions, but after that there's no further checks ever done, so it's a popular mod along with an afermarket pipe. With an Aftermarket pipe and SAI the Bike sounds like a cannon on the over run.
On the 2008 on 1050 models, Triumph recommend and install a non SAI map along with a blank for the SAI and a different mid pipe without the first catalytic convertor in it. For off road use only ...
