Thanks for the update to the old thread guys! It is good to know these things hold up. I live in Las Vegas so I don't have to worry about rain often but when i do it is quite a bit. My truck is without a top about 80% of the year so I have come accustomed to preparing for rain. Good to know that this gauge can take it!
I have the dual GPS/speedo unit that will be going on my bike. The guy at Speedhut was very helpful and said they get lots of orders from guys with old bikes. They even siliconed the bezels on to make them more water resistant. I built a gauge that want even on their page. I have not hooked them up yet but they seem top quality. You can see them on my build thread.
I checked out your thread and I like it, you have a nice looking mount. I just have to come up with a mouting solution for my bike. Thanks again for all your help!
