pretty much any modern day bike comes kinda lean from the factory, for the usual variety of reasons mostly relating to the federal regulations we all know and love.

lately i'm reading that the M8 is NOT lean from the factory.. does anyone know just what AFR and compression these things are actually at, stock?

I'm looking at air cleaners which means since i already have slipons I should probly get one of those autotune gadgets or just get it done properly on a dyno somewhere. but i need to know what kind of animal i'm working with, first =D

Yes he has . I've seen the DK Customs video claiming that TC's run leaner than M8's but they both have very close lambda/afr targets.

 

they run 14.6. 13.7 is as lean as they should be so ya they run too lean.

 

Cruising any size engine can run 14.6 in the cruise area. 13.7 is open loop.
