I find it absolutely ludicrous that LOTS of people have pm'd me the same issue, over and over again, likely about 10 people at this point. These people are afraid to say something or they'll get banned. Yet GG and my local dealer swear they have never seen this issue before.
As a moderator I find that absolutely ludicrous as well. In 7 years here I can probably count the number of people banned on one hand, and my personal count is naught.
The general rules are play the ball, not the person, and all will be well. No one would get banned for identifying or confirming issues, but if you start slandering businesses or people that changes the playing field a bit.
I'd encourage anyone else with these issues to also share their experiences. This is a new chassis for 2018, and while testing has occurred it's still very possible that there could be some unforeseen issues. It happens with all new products and all brands.
In a perfect world QA would iron out all of the issues prior, but it's also an inherent risk you take buying first year upgrades. You'll be a player in the refinement of the product. This isn't for everyone and is downright frustrating if you're not mechanically minded or if the solution is a bit trickier.. but given time things will be made right.
So really, things you should be looking at or that would add worth to this thread is what is actually happening when you press that button. A multi meter and a methodical approach of where the juice is flowing, and where the problem is. Is the stator charging the system when it's running? Are all the grounds earthed? Do they still earth to the back of the top triple? I know my 2013 never grounded well here and I found taking it back to the frame on some bare metal allowed things to work much better.
It could be electrical, or could me mechanical in that the bendix isn't throwing out or catching up. It could be too much compression. No one has put a comp gauge across one yet, I haven't seen measurements for trapped volume, or the squish clearance. I know they are claiming significant increases in power and torque with a new head and cylinder.
As I said earlier, I'd be politely suggesting that the dealer work with a reputable auto electrician. Get that part checked off, and then move on to mechanical issues. Or even something as simple as pulling the plug cap and plug and pressing the button and seeing if the engine spins over without compression.
. Not positive what I'm going to do next. But obviously it's still not right.
