Running lean concerns
Hi, I have a 2008 Tenere and recently replaced the exhaust with a single aftermarket can, my standard air filter was replaced by Yamaha with a DNA stage two filter with the DNA stage one insert. I am concerned that my engine might be running to lean. I have installed my own DIY KEVMOD (thanks kev), but instead I have measured the resistance to drop the temp by more or less 5 � 6 degrees and soldered a 470 ohm resistor inline with the airtemp sensor. I have also removed the stage one insert from the DNA filter and now running stage two. Although the bike is running fine I am still concerned that I might be causing engine damage by running to lean? I will post some pics of my sparkplug colour later.
