mainshaft nut tight

After fixing the alternator, voltage regulator and primary shaft assembly,
filling it with appropriate amount of transmission fluid
etc, I have strange noise from the sprocket/shaft.
I'm able to change gears, but bike doesn't go - it goes,
actually, about 5-10m (15-30 ft), and then I loose
driving power - the gear stays on, but bike doesn't go
anymore. My first guess was clutch string, so I checked
it. Then I checked twice loose on primary chain
with the screw and the cover's hole, as described in manual, that's not it.
I'm going to disassemble rider's left side of the engine again, to see what's going on.

My 3rd guess is loosed mainshaft nut, the left-twisted one.

I tightened sprocket nut as described to 190-210 ft-lbs
(257.6-284.7 Nm). Then I blocked the sprocket with
the blocker (opposite way to disassembly, shown
on picture two), and tried to tighten mainshaft nut. I
tighted it as hard as I could, but the gear hub moves,
moves the sprocket, and the locking does not hold.
I'm afraid I didn't tight it enough, to 70-80
ft-lbs (94.9-108.5 Nm), both damn things move while
tightening. Uhm, yes, I took care about screw aligning
tabs, and the ring etc.

How do you people tighten mainshaft hub nut ? (#1 on
first picture). I'm going to try block it on the top,

with longer blocker, but I'm not sure it's a good idea.
I've seen such tools like these on some sportster site,
but they're, you know.. legendary, uhm ;-)

Another way is to use some impact, pneumatic tool, etc.
Any hints? I hope I didn't break some sprocket's teeth..
well, I'll see when I disassembly it again.

PS. I'm not able to describe the sound exactly, it's
my english, but it doesn't sound like breaking something,
but rather, hm, one element sliding on another (but
lower). Gears shift without surprises, but when I
loose clutch handle and bike starts to move, I hear
this sound once or twice, and then engine works normally,
RPMs grow, but bike doesn't go. I don't think it's
something with friction plates, they're quite new,
I've already had problem with it, and they were replaced
by qualified mechanic.

Ha! Fixed, thankfully it wasn't mainshaft left-twisted
nut loose, but inappropriate setting with shifter nut/screw
(accessible with flat screwdriver in the inside of tube-nut.
The nut is showed here

And the small scratches are shown here

They're small enough not to interfere with appropriately set screw,
just a little bit "polishing" of the surface.
In short - if screw is too tight, it scratches the cover
and element, as shown with red arrows and dots (that's
source of the strange sound), and if it has too much loose,
changing gears "works", but clutch does not release
properly and that's why bike "does not go", even with more
rpms.
Tip - if you didn't overfilled the box with formula+,
this can be fixed without draning transmission fluid.
Remember to setup primary chain tension properly..
To summarize, I had luck again, and my Ully must
like me, undoubtedly.. :-) I didn't have to disassemble
cover again, anyway it's still interesting about the
original guess, anybody tightened it without a special
tool, with the ft-lbs specified in the manual ?

Ya I have used the "Locker bar". I made one out of 1/4 flat stock for my shovel, but it does the same thing. I will of course have to make a new one for the Buell. It is the same idea. I am not sure I completely understand everything you were showing, but by the looks of it, you might have had the locker bar in wrong. It has to be at and angle so that the bar is above the shaft on the engine side and below the shaft on the tranny side. If not, it will just pop out and allow both sides to rotate when you torque down on it.
