At 5200 the graph reads right around 46 HP. Torque in ft lbs. from HP = HP x 5252/ RPM or in this case 46 X 5252 /5200 =46.7 ft lbs
Are 5200 and 66 ft. Lbs perhaps the factory at crank numbers?

Hello Simon,

Do you recommend map #77 or #90 for Motad Shorty pipes? I've read both maps and one better than the other. I was told #77 but #90 appears to show more success paired with high flow pipes whether Motad or SBN. Thanks in advance.

Yes, what DallasNorton said. I'd like to understand this before May. :?

77 is the correct one to use for Commando fitted with after market off road only pipes.

Okay then. What MCC has done with my bike should be sufficient. Thanks for the clarification, Simon.
