I know
XT600 has different mounting points as XT600E = I count on it
But the rear grip on the M6 is probably sufficient when it is there from the manufacturer.
I personally have rivet nuts
The oil draining system will be added as soon as the fixation and correction is verified.
It's not that easy to have a 3D laser device to focus the entire motorcycle at 1mm!
I have to check the points in the space and then I can do more and more variants and improve them.
(Today I made sample from 1mm thickness, tomorrow check mounting points)
