2011 961 - rich mixture at low end of rev range.

Hi,

I took my 961 for a slow run using between 1500 and 2500 RPM. The engine is quite uncomfortable at those RPM. I ran for about 30 minutes on twisties. At the end of the run, I turned the engine straight off and didn't let it idle at all.  I wanted to see what the fueling was like in this rev range. I removed a spark plug to find it very black and sooty. It has NGK iridium spark plugs. 

Now, the 961 is fuel injected so mixture is out of user control. The question I have is "does anyone know of a reason for the ECU to get the mixture so very wrong"?

Has anyone direct experience of hole-sawing the baffle out of a 961 peashooter exhaust?

I have watched a few youtube videos of people removing fixed baffles from silencers by using a metal hole saw to detach the central baffle from the exhaust and then pulling it out the back of the exhaust.

Has anyone done this on a commando 961?

I am worried that it may leave something loose inside the exhaust that cannot be removed. I would really hate yet another rattle.

Low opinion of the 961

I do not own a 961 just a Rotary and a 650 SS, on FB today there was some typically negative comments concerning the new Norton's (Atlas etc) from one who admitted to not owning or riding a Norton and another who is a sales person for a well know dealer who stated that every 961 he has sold has had to go back to Norton to get sorted, following are some of the comments:

"Their current bike has a pretty terrible reputation for build quality and reliability"

This may not be the correct place to put this , but how many other 961 owners have received an invite to look at the new 650 next Tuesday night down at the factory. I don't know if it will be on show at the NEC in the coming weeks but I am still thinking of going to the factory next week to have a gander as I am extremely curious , but if the weather is too bad I will just wait a couple of weeks and look for it at the NEC.
