In December last year I took my speedo off my bike & sealed it up with silicon as I'd been getting fed up with the misting whenever we had warm weather.
I've ridden the bike everyday except for a few days snowed in the other month; believe me, it's had plenty of rain on it both driving about & also when it's parked up all day where I work.
Last week we had some really hot weather for the first time this year- it's been a cold winter- so I left the bike out to see if I'd get the mist & there was a really, really small bit but nothing like I used to get. It disappeared pretty quickly unlike previously where it would just linger in the shape of drops hanging from the underside of the speedo lens.
I'm hoping that tiny amount is just leftover from when I sealed it as I did the job in the middle of winter so the air moisture content was as you'd expect for a grey December day.... I did think that at the time although I left the speedo in the airing cupboard all night to minimise the moisture content.
That's what I hope anyway! I may end up doing the job again in the middle of summer just to make sure & leave the speedo in the airing cupboard for a week.
So the upshot is I think it's OK...if not it's certainly 99% better.
My next post will be to tell you all how annoying I found replacing the oil sensor was but I have to go now....
