Here is the answer to the age old question
I pulled the 2ndaries to get rid of the herky jerky throttle response on the bike. it worked for that:up:
I drilled them out of the rail. The rail is still in the bike, the servo is still active so No FI codes to deal with or jumpers to disable. In other words, the bike thinks they are still there.
The bike was custom tuned prior to the removal and re-tuned after the removal, by the same tuner on the same machine.
Here is a plug for Wayne at Power-Tripp performance:beer:
The yellow line is before removal, the blue line is after removal.
As you can see there is a drop in power and torque from 4-8k the performance is identical (lines overlay each other) in all other RPMs
the worst drop is maybe 4 hp and 2.5 lbs or Tq. To get rid of the jerky throttle response it is worth it to me.
P.S. Wayne played with the mapping in this area to see if he could make any gains. In the end, we stayed with the map from the pre-removal period as all other changes were detrimental to performance
