New 1000RR owner
Big day today. I remember talking with 74Demon 2-3 years ago about wanting to purchase a 1000RR one day. Well, I bought my dream bike. 04 CBR1000RR!!!! wooohoooo. I got it for a steal! However, it has issues.
The bike accelerates fine, but upon deceleration when the throttle is closed, it almost feels like the engine turns off. It won't stall when I come to a stop, but the bike feels like the equivalent of turning the key off when I decelerate with the throttle closed. It's very jumpy when I give it gas. It jolts forward violently as soon as I crack the throttle open again. I suspected it was a bad TPS and what do you know... someone mickey moused the wiring to the TPS sensor. Basically, two of the three wires are spliced with extra connections leading to somewhere...
My question before I start tearing apart the bike tomorrow is, why would someone do this? To bypass something? Any reasoning as to why this was done?

Glad you got your dream bike!
Sorry to hear you're having issues. Do ypu have any pictures of the wiring? How's it done, butt-connected, wire-nutted, or soldered? Or do you mean, literally just spliced and left open?
It definitely needs all 3 wires to work correctly. Look on a diagram and figure out where that 3rd wire goes. It makes you wonder if the PO was diagnosing it too.

There she is! Just needs a new fairing kit.

Problem fixed?
Well, I took the bike apart last weekend and to my surprise, I found an entire power commander wiring harness that was connected to my bike. However, the power commander computer module was missing. The connector plug was hot glued so that the terminals wouldn't short out. Talk about Mickey Mouse lol. I also researched around and it seems like the symptoms that I have described in my earlier posts is the nature of the beast. Seems like newbies similar to me who have upgraded from a 600RR to a 1000RR notice the sensitivity of the throttle more. Anyhow, one problem is solved. Thanks for the help!
