Hello fellow Fighters!! I'm new to the forums and fighter scene. I'm in the middle of a fighter build and ran into a snag I could use some opinions on. I plan to post the entire build once moved. Life, as well as the bike, are in chaos..

I have a 2005 R1. I purchased it with a K&N, Velocity Stacks, Full Titanium Arata and PCIII..
I stripped her of plastics, rerouted wiring, cut the tail down, recovered the seat, added a different taillight and removed the two Arata cans with under tail pipe. I then cut the mid pipe and added a VooDoo exhaust so that it comes out just underneath the right side foot peg.

I started the bike a few times with NO exhaust and noticed a engine light. Even with the new VooDoo the engine light is still on. The bike seems to be running poorly as well. These are the first mods I've ever done to a bike. Can I fix this using the power commander alone? I'm guessing it's just running lean from lack of back pressure. Would this be correct and does anyone have any ideas to resolve this issue? THANKS!!

did you have the mapping changed in the PC ???????

The PC was mapped for the full Arata, K&N and velocity stacks when I bought it. I even hooked it up to my laptop and re-mapped it for these settings a few weeks after I purchased it just to make sure it was all good.. I have not remapped it since it's recent modifications.

You need to find out what code it's throwing, otherwise you're pissin' in the wind.
On the Yamaha, there should be a way to access the code using the dash buttons, but you'll have to consult the service manual or do some searching on the R1 forum.

Oh btw, got any pics of the bike?????....we luvs some pics.

Did you forget to plug a sensor back in after rerouting the wiring?

Push the select and reset and hold
Till you see Diag then let go and push and hold again. Make sure your stop switch is turned off then using the bottons scroll till number 61 this is the error code number. 62 is how many errors you have. after finding out what is wrong and fixing it switch to 62 and At 62 switch the stop switch on to erase the codes.

I will look up the codes and see what it's throwing.
I have taken pics of its transformation, it may be a little while before I have a chance to post em' up. My dad recently passed and I've been living with my mom to help her out. She's now selling the house so most my time is devoted to cleaning, organizing, selling and packing. Trying to get the bike road worthy again as my truck has issues. I'll try to post them soon.

I'll double check my connections but I'm fairly certain they're all together. The only ones I know that are disconnected still are the headlights/running lights harness. But, I will recheck just to be sure.

OK, I just got home and ran the Codes.. I'm getting a 17 - EXUP Servo Motor Circuit (Open or Short Circuit) and a 30 - Lean Angle Sensor. Are these correct Grey???

30- I understand cause I moved a lot of the (under seat wiring) around and still need to make a mount to hold the sensor level.

17 - I'm confused cause everything has already been deleted with the Arata system before I got it. There was nothing to unplug with the Arata.

 

[GreY2231]

Yup those are correct. The exup motor code. Do you still have an exup system still?

sonetimes light stays on if you mess with the servo motor for the flapper valve. or 02 sensior or IAT.

sometimes aftermarket oil filters throw lights

I'm not sure I even know what that is exactly... I have all the stock parts. I noticed the stock pipes have a cat and a piece that looks like a throttle pull on the side of it. I don't know what was done with all the sensor setup when the previous owner put the exhaust on. Either way, the Arata full system has been on, without all the stock parts, and I've had no light until now. I'm confused how a system, that is already set up to run without stock components, can have issues with a minor change to the physical length of pipe... If it was just a "running lean" code that would make more sense to me... I hope you have more knowledge to bless me with.

The only unplugging/plugging with wiring I did was take the wiring from outside the frame on either side and tuck it within the engine/tank compartment. I did remove a large connector on the left side but I pinned it exactly as it came off after relocating it inside the frame. I took pics as to not fudge it up. The other wiring was all taillight and signals... Nothing major.

The exup is that throttle looking system. Turn the key on, then it should do a self check ( turn onecway then back) then start the bike. Rev the engine slowly up to 8,000 rpm and watch the cables to see if it moves at all if not there's something wrong.

Ok im at work so i looked up some stuff for you. remove the cover on the exhaust that covers the exup. On the diag mode with the stop switch off go to number 53. This is the exup diagnosis setting. Switch the stop switch on. The exup should turn fully open, then back fully closed. Watch it carefully. If this does not happen there are a few options. If it looks like it straining make sure its not stuck or that the cables are backwards. And that the exup motor can freely turn. Then remove the cables from the exup on the exhaust. Test it again on the diag mode. If it still doesn't turn. Check that the cables them selves are moving freely. If yes then check the wire connection to the exup motor. If all is good your exup motor could be toast.

Or through the tuning process with the other exhaust the computer "forgot" how to use it
