Flappy Valve - replacement link pipe

You can unplug and remove the valve actuator. The ECU will record a motor fault but there is no warning on the display and no other effect on the bike.
 
Can I just ask, on the motorworks site they list two, did you buy this one:
Exhaust flap valve eliminator pipe stainless steel | EXA46552
or this one:

Remus exhaust flap valve eliminator pipe stainless steel | EXA07514

The first one looks a bit thicker, other than that they look identical and they are about the same price.

EXA46552
the 'superior' option according to the text
bizarrely also cheaper by 60p
 
Have ordered one now, so I can draw it up if you like. Being an engineer I have all of the tools to measure it, just nothing to make it on. If only I had a lathe....:blast
 
Got one today - the Remus one - yes I know bugger the expense. 5 minute job to disconnect the wires, and fit the pipe on my 2010 bike

Sir that would be awesome, and of course there'd be a CNC lathe (and shit hot programmer) available should you need one.
 
I did the same on mine, removed the cables and re-fitted the actuator and plug my main thinking was to save water getting into the plug. I got my pipe piece off ebay think it was around a tenner.

Even with the actuator plugged in the ECU logs a fault as it is expecting the pulley to be stopped in a set position which is not achieved with the valve removed and the pulleys disconnected

See picture below - GS911 picks up that the exhaust valve error message :

There's no need to machine a flanged adaptor. A length of stainless exhaust pipe tube will do the job for under £5.
 
Sacrilege! It is after all a finley tuned piece of german enginering you're attatching it to, of course it needs to be machined...

Exactly what I was looking at. 10" length of 63mm stainless pipe for about £8 on ebay, should make about 3 pieces. But I'm not totally sure 63mm is the right diameter. Can anybody confirm if 63 is correct?

This is very true but I'm a CNC programmer by trade and the flanged version is a more elegant solution.
.... And for me the only cost is time 😊
 
63 diameter x 70mm long

I did this to my bike. Bike is now a happy bike. It made no difference to the sound that me or the misses could tell.

...and would sir be making a batch? (If so I'd be requesting one please).
 
Have drawn it up and sent it to Diamond GSer.

As I have bought it I don't need one, but others may.

Not sure wher we stand on copying someone else's though?
 
Done about 1000 miles since I fitted mine.... Lots smoother! But noisier!
My flappy valve was only moving through a few degrees: from closed to nearly closed!
Also, I seem to be getting a few more mpg. I guess it was running badly with the valve semi-closed all the time. I'd just got used to it!

My bike with it's shotgun cans would benefit from a valve on one outlet pipe. One day, I might get something knocked together.
