Can you post the code ? Should be something like this example for two digits (17) < year, next two would be the month >(05) next two would be the day > (20) last two would be plant / and shift > (68) 1705206B

I've been told by the repair guys that a flaw in the early 450's caused air to get in between the glass pieces which sandwich the liquid crystal, part of the screen fails when this happens. It looks like black dots or the lower half of the screen appears like a gray mountain range.  However, when the polarizing screens are sun damaged and the screen color changes or prevents function; the LCD glass plates may still be fine. If you have or know anyone with a screen from this model (working or not, as long as it's all the same color) I'd be interested in it! If you can help or have a lead where I might locate one of these please let me know.

I was told that the shift pattern was 1st gear down with neutral between 1st and second gear, as you lift into second. It sounds like you are saying that neutral is the bottom and all gears are up from there? If that is how it is supposed to work, that it is working normally. Do you know this for certain? All the Honda motorcycles I've ever known of were as I've described. If this is different that would be great news!

First gear should be between neutral and second.   Are you having to hit the shifter twice to go from second to neutral?   Don’t mean to stay for obvious, but trying to ascertain if there is a click from neutral to first and then I second click to second  or if it goes straight to second….   Or is there a position for first but it doesn’t pull in first?

I dropped two ECU’s and a voltage regulator in the mail earlier today. Hopefully you will have them by the end of the week to use testing
