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.
