Depends on how you care to measure tweaking.
My Ms Peel Combat goes together fine w/o pry bars or wood wedges,
or swear words, but of course that required beating on frozen
spindle so long and hard it tweaked the swing arm
so bad a famous frame fixer send it back as fixed but still
would not pass the spindle no matter what I tried.
Bought 850 braced swingarm and all slipped together fine.
My deer struck- forks bent Trixie Combat, would not
accept the front mount w/o strong wood wedge banging-swearing,
plus the factory headsteady would not fit because the 1" under
tube was shifted 1/4-3/8" to the LH, so needed extra
rubber spacers to mount it skewed and under some strain,
but rides smooth and handles as well as any ordinary Cdo.
A bit more sensitive to side-side combustion issues like
a fouled plus or loose plus wire, or one side of head
gasket blown out or a carb gasket leaking type faults.
I had a hard time to get RGM fork brace to work free
in 1st edition of Ms Peel, could not tell a riding handling
issue at all, but finally check stanchions to find them
tweaked by who knows which crash, replaced and
all fit and worked fine. It was on the slightly binding
stanchions that I've done Peel most extreme testing
to bring Extreme Joy and Elating Surprise ease and smooth
sureness in rather rough dangerous places.
So my firm conclusion now, is its a waste of effort- money
to get any better chassis corrections than just to assemble w/o
being a terror. You simply can not detect the skewed and
mis fits unless binding hard enough to transmit vibration or trying
to keep up with moderns in sweepers or dirt bikes on steep
rough hill side turns. Only real issue on ordinary Cdo's
to get right as rain, is all the drive line alignments.
I'm not saying its not a worthy goal to approach the
World's Straightest Commando, just its only for self
satisfaction and bragging rights, but not other wise detectable.
I had long conversion with Ken Augustine who did this job
and confirms my firm opinion above even more.

BTW all factory cylinders have top surface sloped .003" off.
Have machinist check and fix this.
Also the head steady surface should be indexed to the
gasket surface. Have that fixed at same stop.
Make sure the front mount tabs are parallel.
Check the centering of the spine tube under tube.
Check swing arm lays flat in relation to spindle.
That's about its to get as good as it gets on ordinary
Commandos.
