If you have an older Sportech V-flow chrome windscreen - that's prolly your culprit!
My guages are melted and so are my inners - the culprit - my Sportech V-Flow chrome screen.
See, they apply the Chrome on the inside of the screen; it is shiny on both sides. Well, you can imagine what the shiny, mirrored surface on the inside acts like - a magnifying glass! The sun reflects off the tank into the screen then onto the guages!
I called Sportech and they said that they've addressed the problem now. I need to send them the screen, pictures of the damage, and a quote to repair the damage. They'll replace the screen with a new one and would get with me on compensation.
So, I'm prolly gonna do all that this weekend and send it off.
