Yes, what you say makes sense.
But what I understand is, putting additional preload on the pushrod moves the lever further away from the ideal of being parallel to the transmission case.

I will keep playing with it.

Wouldn't I need to heat it up to bend it? And then, would I be changing it's temper and need to consider things de re metallica?

Things which I know nothing, by the way.

Heck, I can do that in a with a few hammers blows, it didn't even break or rip out the studs.
I doubt that bent your frame if that was the only impact you subjected the bike to.

Both fork tubes were bent and the left leg reflector broke out.

Someone asked about what parts I reused in the rebuild.

I replaced a 1980 engine with a 1981.

I removed the clutch carrier and installed my heavy flywheel so I could keep using my old transmission.

So everything on the back of the transmission should be the same. I used the same clutch parts as before.
The only differences now is that I have Nikasil jugs and larger valve heads.

Where do you get these ideas?
Ideal is parallell to the transmission case at half its travel. (ie, when the clutch handle is half way to the handgrip)
A bit more forward or a back from that is no big deal.
Right now IT IS TOO FAR FORWARD, THAT'S WHY it's touching the frame.

You won't have to bend it, the adjustment will fix it.
Wanna bet?

I'm sorry, I missed that precursor.

Uh, I'm up to date on all my work. Just waiting for the next ... climax ...(when Step1 finishes and Step4 starts).

That is in about 1 hour.
