I 100% agree on it and I want to do it.
However, the stupid guys in the Yamaha service shop have told me that; if
I do so, the bike will run out of warranty.
The explanation of this in reality is, they are lazy as hell and don't want to
deal with it. I already don't know what happens, if I need something within
the warranty in the future.
Honestly speaking, I really don't trust them either; because, as you said there are rarely New Teneres on the streets. They just know the engine;
because it's a 660. I started to see new ones; but just very few.
