Last year i picked up a 2004 wr450 with a supermoto conversion. And today i was cleaning it and noticed that two wires were not connected. Im not sure what its for or if it needs to be connected.

it's the plug for the throttle position sensor (tps).

some people run with it unplugged, some with it plugged in. it is "supposed" to help smooth out the engine when running constant throttle settings from what I understand, and some have success with it and some don't. once removed the adjustments that it makes based on the throttle position are not there anymore.

ride it like is. see what you think.

plug it in and ride it, see if you notice any difference for better or worse.

there is also a procedure in the manual to set the adjustment of the sensor if it's ever been removed from the carb.

ALso, what kgsloan said is correct. People who do a lot of street riding usually prefer to have the TPS unplugged. The TPS changes the timing map according to the position of the throttle, and that sometimes makes the RPM's feel and sound weird while riding street...at certain throttle position, you can feel the timing change back and forth like it cant decide between the two.. It isnt noticeable really on dirt.
