it is, here is a short vid of mine stock with only the bearing and battery mods done then.
Just keep following the break in procedures, you can turn the LSN in some but at break in it should not idle very long if at all due to how rich it is set. I imagine you will have to continue feathering it until break in is completed. I know the LSN factory setting on mine was way too rich. I wound up turning the lsn 1.5 turns in from flush versus the factory 1 turn out. Others in various areas have had different results.
Once you have the hsn set after break in do the lsn pinch test to get it set right. If you need info on that test let me know. There is another thread on here i made with that info for another member looking into the Mg16.
