Hi There. Just bought a 2 valve 2010 Norge. After riding for about 15 minuets the clocks started to mist which surprised me as the bike had been dry stored for some time. I thought a vent would be a possible aproach. There are a few posts on the forum on this topic but the link on how to do this doesnt seem to function. Could anyone help plrease. Everything works as it should just condensation on the clocks inner glass. Thanks, Duncan
Hi, They all do that Sir. There are small vents on the casing but they are insufficient in our damp climate. You can improve the venting very carefully as the circuit board is close to the casing. It’ll still mist in winter, early spring and later autumn, but clear more quickly. It’s something you learn to live with.
Thanks for your reply Maxrevs. I’ll have a look at the vent. Sounds a delicate operation to enlarge it. I’ll aply some heat with a hairdryer to get rid of what’s there and see how it goes. I’ve ordered my shower cap.
I have come across an old(ish) a pdf file that shows the possible damage that the misting can cause and how to help cure it. If you PM your email I will forward it on to you.
Thanks Maxrevs much apreciated.

Email sent. The clocks will mist, but at least you’ll know it won’t cause further damage.
I have a theory about the misting problem and I don’t think its from the top i.e. coming through or around the bezal. I always get/got this problem when I had parked up after riding in a lot of rain and what I think happens is that when you lock the handlebars with the front wheel turned towards the prop stand any vapour off the engine as it dries off rises up past the tank and then to the underside of the console (I have the nose fairing which also funnels it.) and the vapour enters the speedo through the vent(s) located underneath. Having tried locking the handlebars in the opposite direction I do get reduced misting.
How good this theory is I don’t know
Hi Brian.
I have seen the guide to increasing the vent size but if your theory “holds water” then enlarged vents wont necessarily work. I have contemplated drilling a small hole in the perspex glass and sealing with a gromit when not riding in dry conditions or when the bikes sleeping in its garage.
Cheers and thanks for taking the time to send your thoughts.

When I had a similar problem on a non-Guzzi, I clipped a large bag of dehumidifying crystals over the speedo whenever the bike was garaged. It didn’t stop the cause of the problem but certainly eased its consequences.
I had forgotten to add a bit more reasoning.
When you are riding the clocks are getting warm from the motors and lights within the console and therefore the air within is warmer than the surrounding air (higher pressure) when you stop the outside of the console is colder (especially when raining) and the pressure within will now drop reducing the pressure and sucking in outside air to equalise.
I do sometimes wrap the front of the bike in a bag and connect a dehumidifier to try and dry it out, but this time was unable to get all the moisture out - usually works.
This makes sense to me. So the vent actually acts as a suction point for damp air as the clocks cool. In Scotland where I live humidity is usual in the 80’s during the colder months (nearly all of them.) so the clocks will be constantly getting recharged with saturated air. Taking all this into account I am going to try my top vent idea and will post the results in due course. Many thanks for all the replys on this topic, very helpful in formulating a practical solution.

Thanck BXX, A further prong to my attack.

I had been thinking about goretex over the vent.
Ingenoious, So the clock can breath but not let moisture in as with jackets etc.
Your on fire Brian. Thanks. D
My logic is that, if you can’t make it air and water tight, then vent it. A bit like early 80’s Ducati fuse boxes. That way the air flow will clear the misting fairly quickly. I put a heater under my bike while it’s in the shed. This only helps to minimise the misting. At 17 years old and 70,000 miles they’re still working fine, except a wee bit misting.
