Yup. I used the off the ground measurement.Yes this is done on OEM Stand. Bike completely unweighted.
Hopefully ReVolter can chime in and confirm his measures similarly

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.
I'm sure they will refurbish the parts that are usable. instead of binning the whole powertrain.Wow. A 4.000$ assembly for a faulty bearing.
Is your bike still under warranty?
Who will?I'm sure they will refurbish the parts that are usable. instead of binning the whole powertrain.
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.Who will?
I doubt any usable parts can cover the price of shipping from "Land of NOD" to the factory.

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.
Plus, the cost of the re-branded Chinese parts probably isn't nearly as high as we assume.This is my assumption and what I would do in Stark's position.

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.From Stark; I getting a Gen2 powertrain. Is that actually an upgrade?
It's strange that the actual manual and Sam both say 25–32 mm (again ?).Was asking Stark's SAM AI a few questions today and it seems they have updated the chain slack recommendation internally, but have not updated the manual.
Seems they are recommending 45-50mm now.

EDIT***
Just got a reply from stark and it is so. Just incase anyone is interested. Quite a big change from 25-32mm

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 ?).
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.
Yes, but I find it very odd that SAM says it's 25–32 mm again.I thought the newest was updated to 45-50mm. The previous numbers could cause undue wear to the drive system was my recollection.

Yes, it is an upgrade. Gen 1 had a black plastic inverter cover, that is some cases developed cracks at the mounting bolts.From Stark; I getting a Gen2 powertrain. Is that actually an upgrade?
