What is a code 17 mean on a 2005 r1

There is a malfunction in the EXUP(exhuast control valve) system. Suzukis do this when the operating cables are out of adjustment. You should see a qualified dealer or other technician for this adjustment.

Your EXUP is the butterfly / valve that is in-line between your center muffler/Cat and the stock exhaust can. It is controlled by cables from a servo motor under the tail / behind the rear shock.

The EXUP errors (17 and 18) are because:

1. you removed your EXUP servo and/or valve when you installed your exhaust.

2. your EXUP valve is stuck / cables are seized up

3. your wiring harness is disconnected from the servo motor.

The rev counter goes from 0 to 7000 revs then back to 0

that is the indication of the exup valve malfunctioning. it tosses the code of 7000 rpm for a few seconds on start up to let you have an indication that there is a problem.

Does anybody out there knows anything about R1's I'm having problems with code error 17, and Exup motor not working.... Is there a way maybe connecting the wires to the lil motor that control the intake...

If the code is coming up then your exup valve is probably stuck open or closed and needs to be removed and greased. when you turn the ignition on the bike will do a exup check and preform a cycle which is the noise you can hear so watch the valve cables and see if they move, if they dont then the exups deffinately stuck!

I have a thunderace and the rev counter keeps jumping from 0 t0 7000 revs

7000 rpm is a self diagnostic code that either your exup valve is not being detected or the valve is locked up and not moving. If you put a header on your bike and took over the exup valve servo motor, you are going to have to put it back on. It also changes the mapping of the ECU and will not let it rev to redline when the Exup servo motor is missing.

The error code 17 means you have a malfunctioning EXUP exhaust valve, or EXUP servo motor. It could be that your servo motor has fried, could be that some wires got loose, or it could be that your exhaust valve just needs a good cleaning and lubricating, if it's had a hard life.

Yamaha 2001 r1 been stood for 2 yrs ;got back on road ;rev needle keeps going from 0 rpm~~7000rpm all the time;bikes runs but must of lost half the power of the bike ????

Hi There,
Got this from my copy of the Yamaha workshop manual for this model

The YZF-R1 features a self-diagnosing system for the following circuits:
1. throttle position sensor
3. fuel level indicator light
if any of these circuits are defective their respective condition codes will be displayed on the tachometer when the main switch is set to "ON" (irrespective of whether the engine is running or not)

1. throttle position sensor a) Disconnected b) Short-circuit c) Locked 0 - 3,000rpm
2. EXUP a) Improper connection b) Short-circuit c) Servomotor is locked 0 - 7,000rpm
3. Fuel level indicator light a) Improper connection 0 - 8,000rpm

It looks like you have a problem with the EXUP Valve on yours, probably seized or maybe cables not moving freely
Hope this Helps
