I took out the active intake solenoid on my '09 1125CR and installed the Buell resistor. The job was cake aside from getting the breather line hooked back up.

I was going to zip-tie the throttle bodies together like most here have done, but I didn't see any way to do. I did a lot of playing around, and I'm convinced that on my bike, they both are linked. Even if I press on one or the other with my finger, the other will move as well. I looked long at hard at the linkages and watched how they looked and I can't see anywhere that could be tied together.

Has anyone else done this on an '09 and noticed anything similar?

On a side note, the heated grips are GREAT. Tonight I'll built the plug for the GPS to go into the other accessory socket, and I might mess around with putting on the new turn signals. I'll have to drill a couple holes in the flyscreen to do it. Fronts will be cake. I'm worried about the rears for clearance issues with my hard bag setup.

The front and rear butterflies ARE linked together.
What isn't a direct link is the throttle cable and the butterfly shaft.
That's where you tie them together.

Open the throttle and then pull the solenoid cable.
Watch the 2 plates move independently at the butterfly shaft.

Hmm... I'll have to take another look, then. The solenoid is gone - hope i can remember where it hooked up to!

There are some pictures on this thread that might help.

Ya know the clunky on/off throttle transition at low rpms? How much does the 'noidectomy help that?

Zero as far as I know.

Pri - I noticed the same thing - it's amazing to me how much smoother it gets by revving the engine up another 1000 rpm.

The 'noid has nothing to do with that, though.

BTW - I was AMAZED at how much the friggin' thing weighed, and how big it was.

if u move the throttle it goes towards the down and to the front in a circular motion(do'oh right) but the part the gets moved by the soleniod when operated moves the opposite way. it took me a second myself. but thanks to the great people and pics on this site i zeroed in on the silver bracket, that the soleniod operates.
so story short the part that u have to tie moves in the oppposite direction when in use.

The idea on the low speed stuff was that the vacuum pulses are strong and pronounced at low speed.
With the spring coupling of the 'noid, there was a possibility of the butterflies fluttering with the pulses.

Tying them together gives you a direct connection and you'd feel any fluttering.

Loretta is almost as smooth as silk, at 100/100AFV on the 0505 flash.
Can't wait till she learns, about 400 miles since flash and ECM reset.
