Hi all,
I'm slowly becoming very active in this forum which I guess is a good thing. After seeing the error 26 I've finally gotten the time to take the plastics off the side and get into the internals (still waiting to get the airbox off).. I have seen that the clip for the knock sensor is pretty much rooted and the wires have some exposed areas and it looks like a previous owner has heat shrinked their own job onto it. My question is would it be reasonable to cut the old sensor off and solder a new one onto the existing loom? And is there a way I can test if this wire is even connefted IE turn the bike to accessories to see if there is a reading with a multimeter or does the bike need to be running for the sensor to activate?
Cheers
Shaun

The wire goes to a connector on the ECU, so it would be possible to test for continuity between the ECU and the sensor. This would involve a bit of circuit reading and manual dexterity.
Repairing the wiring would be possible if you can locate a new plug, suitable wire and crimping tools. to simply splice in a new bit of wire would be a challenging task, and word need specialist knowledge and skills.
The right Knock sensor failure indication is fairly common, not sure if a solution has been found.
Sensor connector available here..

There is a high likelihood that the ECU is damaged. It is worth replacing the plug but the most common result is that the error continues because of the ECU.

Ive pulled the fairings off the RHS while I wait for parts (Cracked my fuel joiner hose and my Honda shop thinks it will take 3-4 months to get one in from the states) and Ive noticed that the previous owner has done a touch up job previously but haven't insulated the wire/area correctly and has burnt away some of the wires sheath leaving parts of the wire exposed, so I will be ordering a new connector plug pigtail and splice & re solder the wire with some heat shrink. Ill probably look at added some exhaust wrap to kill some of the heat getting into that area. I had a look at the ECU as well and looks like the previous owner has already installed another ECU from a wrecker in victoria (Business markings) so Im hoping that that ECU isn't faulty and it could just be the exposed wire causing some issues (Possibly damaged in other areas)

Hi all I have the dreded F1 code and a parts bike Is the ECU a simple swap to eliminate this

You need to check the cause of the F1 error and find if it is a code 25/26 first.
You need the key(transponder) from the donor bike as it is programmed into the ECU.
I would also swap the knock sensors if the ECU fixes the problem, as they will kill the new ECU after a while.

Code comes up as 26

Swapped the knock sensor and the ecu the knock sensor was not the issue but the ecu
Now to do some new keys AGAIN

Well done Timbo :hatwave

F1 code 26 rhs knock sensor
I have a spares bike i bought thankfully i did that
So i swapped the knock sensor tested the loom
Then the ECU was needed so swapped it swapped the key chips in the keys and had another genuine key made and i programmed it
Not certain what caused this i did buy some 91 unleaded and it did ping a little Anyhow my ECU was buggered and nobody seems able to fix the ECU either
These ECU must be getting scarce
