hmmm, it sounds like you have done most stuff already. so i'll just suggest some things that i have seen cause "Phantom" problems.
one check your regulator rectifier. make certain that you do not have ac bleed threw. it can cause some weird symptoms. (but i have never seen it cause what you are describing)
two check the ecu, i have had ecu's fail and cause similar symptoms.
So I checked the TPS. The resistance is within spec. But when I check the voltage it was reading 4v. It's suppose to read .65-.75. Adjusting the TPS will only vary the voltage by .5v. So i'm thinking this is pointing to the ECU (I believe it is sending the wrong voltage to the TPS and possibly other electric on the bike).
My thought is that the ECU reads the difference in voltage going to and from the TPS. So its reading the right potentiometer (TPS) postion, allowing it to give the right reading in Diag mode.
I have a ECU off ebay coming and I will be swapping it out as soon as I get it. Keeping my fingers crossed. If that doesnt work im thinking ill get a new tps.
Does this make sense?
Ill keep u guys posted.

so it's reading 4v at idle? that's backwards. normally, a TPS starts at .65 approx. and as you move the TPS from Idle to WOT, the voltage slowly increases up to around 4v. does it have 2 or 3 wires hooked up to the TPS?
usually with a 3 wire TPS, if you hook your black meter lead to bike ground and probe the wires on the TPS, you should get 1 wire is nothing (ground), 5v which is your battery input, and then the last will show the variable voltage.
keep us posted....
