Yup. I used the off the ground measurement.

Thanks, this is good to know. I thought it looked so tight for so long, and even had others comment on it.

I had my bike on a stand with the chain off. Powered it up and with throttle applied increased the speed and got a noticeable "Growl" out of the motor near the counter shaft area which got louder as speed was increased. I'm thinking that the tighter chain adjustment may have compromised the bearings in the motor. Got a support ticket started and sent a video to support of the condition. We'll see.

1st Gen MX. Hours; my phone sez 35 but I'm sure it's higher than that number. Also I've never checked for this condition before; I just happened to have the bike on a stand with the chain off and thought I'd run it up. Then I heard the noise and remembered about the chain slack change/update.

Just got my reply from Stark: Powertrain replacement required.
Wow. A 4.000$ assembly for a faulty bearing.
Is your bike still under warranty?

Yup. Aren't they all still?
I don't know for sure if it's a bearing or something else. Sounds like a bearing but what do I know? Maybe if the bearing/s are that noisy, more than just the bearing/s is compromised.

I'm sure they will refurbish the parts that are usable. instead of binning the whole powertrain.
Who will?
I doubt any usable parts can cover the price of shipping from "Land of NOD" to the factory.

This is my assumption and what I would do in Stark's position. Instead of sending out a replacement bearing and hoping that the bearing was the only issue, then having the customer or dealer pull apart a piece of my proprietary equipment to do the replacement and hoping they do it correctly. Its easier for me to just swap the whole powertrain. When the customer ships the powertrain back to me, I can check to confirm points of failure, if its just a bearing, then I can replace the bearing and then i'd have a working powertrain that I could put in a team bike, or demo bike etc.
Analysis of failed components and making sure the customers is happy that I've solved the issue completely, the first time is more important for a new company.
Makes sense from the perspective of the factory, although it doesn't look to me like that is part of their business model.
From the perspective of the user with expired warranty; the unfixability of key components and total lack of knowledge base on how to do it is rather uncomfortable.

From Stark; I getting a Gen2 powertrain. Is that actually an upgrade?

Plus, the cost of the re-branded Chinese parts probably isn't nearly as high as we assume.

Well at least it comes with the updated oil drain plug with the 13mm head instead of the "lets see if we can spin out the soft aluminium" torx only option.
It's strange that the actual manual and Sam both say 25–32 mm (again ?).
The link is under the manual button on the FAQ page.
edit : I just found an other pdf manual where it says 45-50mm.
I sent them an email to get a clarification.

I thought the newest was updated to 45-50mm. The previous numbers could cause undue wear to the drive system was my recollection.It's strange that the actual manual and Sam both say 25–32 mm (again ?).

Yes, but I find it very odd that SAM says it's 25–32 mm again.
Another try, just 1mn ago
Every owner manual (EX, MX, MX 1.2 and SM) says 45-50mm from there
I suppose 45–50 mm is the correct value, but they should have clarified this.
Even on YouTube, their video is still using the older 25–32 mm, but they don't mention this.

Yes, it is an upgrade. Gen 1 had a black plastic inverter cover, that is some cases developed cracks at the mounting bolts.
The Gen 2 also has an improved charge plug. Just look closely the first time you remove the charge plug cover, there is a button on the bottom to release it.
