Looking at the parts diagram above, and at the service manual, the reed valve assembly is not complicated. The cover, the reed valve, and the port plate. I can't tell if it is possible to install the port plate backwards. Maybe a possibility? There is a good pic of it in the service manual, but hard to tell. Django, any ideas?
From what I remember about my VTX1800, it may have been possible to install the REED valve membranes upside down (The PAIR system on many Hondas is very similar). In that case it would be venting during the exhaust cycle through the PAIR Valve Plumbing.
To verify if this is the case, I would disconnect the PAIR Valve hoses from intake ports 3 and 4 as shown in Django's posted illustration and briefly fire up the engine. In theory, you should then see/feel exhaust leaving through these ports if the membranes are upside down/backwards. At least with the hoses off, you might be able to hear if that is the source of the clicking. Then, it would be a simple matter to correct or adjust the membranes and you shouldn't have to remove the valve cover to do this.
Actually, there should be no reason to disassemble the REED valves at all when doing a valve inspection/adjustment (at least no reason that I am aware of). For that reason alone, I am starting to doubt that the REED valves may be the source of your noise, but hey, you never know!
