So I picked up this 04'' 600rr less than a week ago....I knew it had some minor work needed but since then I've found out the TPS was unplugged and that seemed as though where my power loss was coming from.

After plugging in the TPS my gas mileage went from the 35mpg range down to about 8-10 MPG.....i made it maybe 50 miles shooting flames on Decell and slow revs. The bike pulls HARD...VERY hard...runs like a raped ape after a banana as long as the tps is plugged in....but I cant deal with the bad mileage..and the flames dont seem to safe heh.

So im guessing before they sold the bike they had unplugged the TPS knowing there was some sort problem before I purchased it.....with the TPS un plugged the bike runs fine but lacks throttle response and any sort of power over 10,500 rpm's.

Only visible mods done to the bike are mostly visual....and Two Brothers slip on....and pipe replacing the Catalytic converter. I've pulled it almost completely apart and found nothing else has been disturbed...even the air filter had'nt been replaced.

The Bike has 15k miles on it, shows no codes nor does it burn oil or have ANY prolems other than that forementioned.

Anyone heard of a similar problem before I go dumping 300$ in to a power commander and some money in to getting it diagnosed at the dealership......I dont even know if a power commander could lean it out that much to keep from burning soo much fuel....Any help would be appreciated. Thanks.

A power commander wont fix your problem if TPS is malfunction.
You need a new or used working throttle body.
You should be getting 50 mile per gal with a working TPS.

Bad TPS or unplugged TSP will throw a code. So if it doesn't throw a code when its unplugged, They might have jumped a wire or soldered in a resistor to simulate the TPS being plugged in.

I would look closely at the wires to it to make sure they wern't tampered with.

And a PC won't fix it. I get 41MPG, I would like to get 50 but I ride like 85 MPH everywhere so maybe that drinks a bit more fuel.

it does set the code off for TPS when it's unplugged....I also checked the ohmz on the tps and it doesnt seem to have any dead spots in it... im not sure exactly what the range should be though....adjustment might or might not help if i've gotta replace it anyways I might just mess with it a bit

Unless you have a speedo healer, your MPG won't be right cause your odometer is incorrect. Sorry to go off topic from OP.
