TE/TC 2016 Broken speedo

Only fails on the 300.
All Te, fe have same part number..
Go figure

I dried mine out, removed the screen, cleaned with metylated spirit, roughend the edges of screen and casing, and super glued it back on. I then ran more super glue round the edge of the screen so it soak in the gap.
So far its working again and dry. It's survived a trail ride in torrential rain, and a jetwash.

Fingers crossed for ya..

I have the same problem with my '16 TE250. it has done these for three times ever since i bought it last March. did the silicone beading along the casing joint and under too (even beaded the batt door and screw holes).. but did not cross my mind to apply some between the clear display at that time. Third time was not charming at all. It totally died after 13hrs, and one of the led warning light even snapped off caused by a corrosion/rust. informed my dealer but looks like he ain't doing anything about it.. so i got me an hour meter instead. and yes, i LOVE the bike very much
