Hi guys (and gals)

I'm new to modern bikes and I recently bought a zx6r p8f, and this might be a dumb question but on the exhaust at the bottom of the bike, near the belly but on top of the pipe are two devices with wires going to them. What are these?
I heard somewhere they pre heat the exhaust or the catalytic converter. Is that true and if so what purpose does that have?
Thanks

I'm not 100% sure of what your talking about but I think you are referring to the exhaust valve system which changes the back pressure inside the exhaust based on throttle position and air flow

 

[vikingvirusUK]

I think that valve system is further back under the tail before the silencer above the wheel but these are just after the down pipes combine near the front. If I can figure out how to post a picture I will.

Hiya these are the devices I'm taking about. Hope this picture shows XD

Those are o2 sensors in the exhaust not sure why there are two but that's what they are

 

[vikingvirusUK]

Under the tail before the silencer is a part with two throttle cable like things going to it. I assume these are the valves for back pressure?

Awesome thanks for your quick response

Where abouts in the uk are you,and yep they are O2 sensors they send a signal to the ecu etc and help with the running of the bike

 

[vikingvirusUK]

XD I see, so my pal was right! Do these only come on when the engine is running or when the ignition is on?

 

[vikingvirusUK]

Ok getting conflicting responses XD

 

[vikingvirusUK]

Oh sry I'm near Plymouth in the sticks a town called kingsbridge. Lovely windies and coastal drives. So anyone nearby that's up for a drive?! Let me know

 

[earlthepearl]

I made toast on my exhaust tonight.....
That's what them wire were 4.....

 

[byte2022]

They come on when the ignition is engaged because they do need to warm up however no one ever let's them.
