I just pulled off my ECM connector and checked the resistance to my TPS. 

I got some suprising results.

Pins 55-53 was 3300 ohms decreasing to 1330 smoothly

Pins 55>46 was 2630 Solid

Pins 53>46 was 1620 increasing to 3330 smoothly

These readings make me think I'm doing somthing wrong, got the wromg pins or something.

Pulled the TPS connector at the front intake and got these readings use two differant meters.

55> 53 Infinite,  55>46=6020 ohms , 53>46=INF.

Bike seems to run pretty good. But sometimes it feels like one of the jugs is running at 1/2 power.

If I  get stuck in traffic and it gets good and hot,  I'll pull out of traffic and go down the shoulder

running at 2K rpm in 3 gear it will smooth out. I have stop at a rest stop before when it was

running poorly , got a drink  and came back out, turned the key on and off a few time tring to

get the "R" to come on (another ?). When it did, bike started up & was smooth again. vary hot day!

Has anybody done these reading of the TPS @ the ECM before. 

Someone on one of the forums said they adjusted it for 1000 increasing to 5000 when you turn

the throttle. There is no adjustment to change the position of the reading on the TPS that I can find .

Its good or bad or confusing.

I'm guess battery cables tight? See if battery is good. Pull plugs and see what they look like. If they look ok switch holes.
Check coil or plug wires.
Spray something up around FI body's when bike is running and see if idle changes if so then you have a leak.
