They might. Wouldn't be a problem though... remove 'em, then spin the nuts off.

You want them to come out anyway, makes it easier...
You’re selling me on this guys!
They also had the thicker/stronger racing studs.
Good luck finding those...

Well, Kenny Roberts' mechanic did it long before us.
Do you think they made all their secrets public?
Don't get me wrong guys. I'm not saying it's a bad idea, not worth trying or it won't work. I just have reservations.
Not to be contrarian, but I am from Missouri.... show me.
A yellow piece of paper with an unknown author is..... well, a yellow piece of paper with an unknown author. I don't discount the possibility they existed, but I ain't seen no proof. So, they listed p/n's for the "hot cam", the racing valve springs... pistons.... but they "hid" the fact they used fatter studs.
Have amended post #31 for clarity. Number is number on lower engine case, height is installed height from case, length is end to end uninstalled.
just shows how hard it is to write concise clear instructions.

If you think that cam is exactly the same as was in KR's engine I got a crate XS1 to sell you.
Back when I raced off road the factorys occasionally offered "works bikes". Supposed to be the same as the factory boys rode. They weren't.
I worked for a HD dealer for a year. He was able to get a XR750 for one of the local flat track boys. He spent months do basic mods that should have been done when HD built it. The factory race teams never divulge every thing they do or know.
Thanks. How does this look?
Never said it was the same. What I'm saying is Yamaha had a catalog so you could make a "race ready" bike. They wouldn't have lasted long in the racing business if they'd sold you the stuff to make a race engine.... that'd blow it's friggin' head off 'cause the studs were too weak.
"Here.... have a big bore kit... and 11 to 1 pistons. Oh... and here's a wild cam to go with it. By the way, don't even think of crackin' the throttle wide open.... you'll be wearin' that head." Now there's a sales pitch to die for.
Here's the bottom line. Just lie to the threads and tell 'em you put loc-tite on 'em....'cause they'll never know the difference. Once that stud is bottomed out in it's hole, the twisting and tensile characteristics will be the same as one with loc-tite.... as in it CANT move any more than it already has. That would also hold true for a fat racing
Looks good Jim

Haha, yeah Jim, that's part of the disappearing horizon.
From Paul "Bob" Bertaut's defunct 650Motorcycles.com site.
Lotsa good stuff there, gone now.
Looks like Raceware offers 10mm studs now...
Well you shouldn't need fat studs for an XS performance 750
When's the last time we heard of a broken stud on XS650? crickets.......
Hey I got a Bertaut "flat track" motor in madness.
it's taken a cubic ST of abuse and at least 10K miles since I've owned it.
I used to have a stud finder, but the light was on constantly every time i used it.
Groan....
Factory's didn't give a shi!t about the independents. I knew quite a few guys that had "factory" support and then a couple that actually were on "factory works" bikes. They told me the difference was night and day. The factory's would sell parts to independents to make them competitive but unless they were true talents not winners. Race teams hold their cards close to their vest.
Jim wasn't too long ago you told me you went with what your knowledge and experience told you over what a Yamaha manual said.
