Nik said:Gents - thanks so much for the feedback.
It is indeed vacuum operated. Will take some pics tomorrow.
Sorry for the ignorant questions....
- is there an easy way to test if this is the problem (didn't realise the exhaust would click if the vacuum had failed!) ?
- can I get the replacement parts easily or do I need to contact Akra ?
Thanks so much - am hoping you're right. (Although it should shame the alleged Akra experts who tested it!!)

I've got full Akrapovic titanium full systems fitted to all my race bikes :thumb:
DucatiRob said:The solenoid could fail in different ways, mine basically burned out, so was not actuating at all when button was pressed.
It could just be sticking and trying to actuate but not making it. Tap with a screwdriver might free it up in this case. Unlikely, but could it be wired up incorrectly, if wires are reversed then the solenoid might be trying to shift the valve in the opposite direction. Also, most vacuum solenoid valves have three connections, only two are required so one is usually blanked off. If the vacuum pipes are connected to the wrong way round then this might also cause an issue, likewise the small check valve!
Nik said:Thanks !! Will try to fiddle with it over the next day or so.
I did notice that one or two of the rubber hoses were held tightly in place and may have been a little pinched, which may have restricted the air flow a little.
I suspect (hope!) maybe it just hasn't been wired up correctly which could be an easy fix. I do have the Akrapovic instructions but ideally would find a local mechanic to help diagnose and fix. Going back to the place that installed is a bit of a treck and it's tough to keep taking random days off work to sort it.
Thanks again for all the advice. :thumb:
