Well what comes to that bike and engine trouble that while running at Closed loop it does not matter too much as ECU will sniff data of the sensors , but on closed loop it will lean out a lot.. as much to destroy engine.. who knows, but there are lots of bikes what has after market slip on and there is not epidemic of blown engines.. :)
Slip on cans are commonplace in the west, but then reprogramming the ECU is also common. Most western dealers have specific programs for each system. Change your Triumph or Honda to an Arrow slip-on or Akrapovic system, yep there's a program for that.

OK, let's say for sake of argument Triumph are wrong, in fact that modern bike's ECU can adjust for any lack of fuel in the mixture. Then there's an unrelated engine problem within the 2 year warranty, your dealer and CFMOTO have then got their escape clause.

In fact there have been lots of cases of engine failure both with CFMOTO and Benelli bikes in China. There is also a massive culture of wacking on cheap unrestricted mufflers for show pony 'individualism' and a nice loud noise, unrelated?

I agree that it probably doesn't cause engines to get blow up, but premature valve and ring damage possibly. Bike runs hot enough without pushing it to be more lean.
