I wonder if they're going to release the speedo separately as a necessary upgrade or together with a new bike, say, 650NK-1. I mean, what's the use of just upgrading a speedo by itself? Is t like the buggiest part or something?
Speaking of an ER6N speedo, you said it fits perfectly. So have you finally installed it or not? And how much does that retail for? I know that on 650NK the speedo is connected to the main circuitry by a huge plug. Do you mean the plug fits the speedo from ER6N or do you have to modify the connections somehow?
I think we're experiencing similar problems: say, I had to change the speedo assembly after that misting problem occurred (as seen in my review of the bike). A couple of weeks later it started showing weird fuel levels - the readings were always lower than what was in the tank. And I had the same problem with the tank being read as "empty" when in fact it was half full. Then it disappeared all by itself and now I have the readings right and what I see on the gauge is (pretty much) what I have in the tank.
But then there's another thing: when I turn the key and engage the engine killswitch (the big red knob on the right handlebar), the red EFI warning light blinks about 7-10 times and then shuts off. The bike starts and rides just like it did before, no changes. I wonder what that might be because that light wasn't blinking before. So is it like my speedo started doing a right thing or the readings are off the wall - I know not.
