Did a complete dyno test run on my 06 K12S with 7.0 SW.
(146,6 [email protected]
at the rear).
The CO, CO2, O2 and HC values (from the exhaust) was interesting (at least for me).
I just want to share this with you.
CO = 2 - 4% (normal/typical: 5 - 7%) - the purple line
CO2 = 11 - 13% (normal/typical: 10 - 11,5%) - the green line
O2= 1 - 2% (normal/typical: 0,8 - 1,1 %) - the blue line
HC = 20 - 50 ppm (normaltypical 600 - 1200 ppm) - the yellow line
The conclusion is that this bike is running EXTREMELY lean and clean. Normally the HC value (i.e. unburned fuel) should be 600 - 1200 ppm. Lower values will normally make the exhaust too hot. The guy that did the test has never seen such low HC values.
The high O2 values indicate that the engine could burn more fuel (and create more hp). The high CO2 and low CO indicate a very very effective combustion.
This beast could easily create more hp just by adding a little more fuel. This engine is screaming for more fuel ;-)
