I replaced my Oem exhaust Studs, Nuts and Bolts with OEM and took measurements of the New and old ones.
This will help those looking for bolts studs and nuts for the studs of different then OEM.

Front/Rear tap-end studs

(Rough tap-end stud measurement-
Tap-end 14.60mm
Body 8.69mm
Nut-end 18.67mm)
(Rounded off to nearest tap-end stud measurement-
Tap-end 15mm
Body 9mm
Nut-end 19mm)
(Tightening torque 11ft lbs/132in lbs tq)
Oem part # 95617-08625-00 (total of 2 unless replacing rear head exhaust studs aswell as front then 4 are needed)


Stud flange nuts
M8- 1.25x 11m ( Tightening torque 14ft lbs/168in lbs tq)
Oem part # 90179-08410-00 (total of 2 unless replacing rear head exhaust studs aswell as front then 4 are needed)
Removal tool size - 12mm wrench/socket head


Rear stainless allen/hex bolts
M8- 1.25x 30m ( Tightening torque 17ft lbs/204in lbs tq)
Oem part # 91314-08030-00 (total of 2)
Removal tool- 6mm Allan wrench

OEM copper crush gaskets

Use anti seize.

I have more pictures then allowed to post so I have the pics made into a video.



Removal of front studs -
This way helps if your studs are stuck or the nuts keep spinning off instead of removing the stud.

Before you put any of nuts on the stud to remove, stick the closed end of the wrench on the stud with the handle angled towards the cylinder head (if your wrench has the bend towards the end.
Then screw the nut all the way to the wrench but leave enough room to be able to move it off the nut so you'll be able to turn them adjust.
Then add the 2nd nut and tighten it down.
You'll been 2 wrenches. Or 1 wrench and a socket/ratchet. (12mm)

Use the 2nd wrench or socket/ratchet to tighten the outer nut while also trying to un screw the stud from the inner nut.
So tighten the outer nut the same time your trying to back out the stud.
This should work as I've done this many times.

Showing the wrench on the nut and the angle of the wrench towards the cylinder head.



Showing the wrench off enough to be able to turn the adjust to turn again.



Showing the use of the socket/ratchet instead of the 2nd wrench tightening the nut while using the wrench to break the stud loose.
Also using a wrench for leverage on the end of the wrench breaking loose the stud.




Exhaust stud removed with both nuts.




Installation on front and rear studs-
Install both old nuts to the new stud and tighten together.
The shorter threaded end of the stud inserts/threads into the cylinder head.
Apply Anti seize to that shorter end before instal.
Thread stud into the cylinder head by hand with your fingers to prevent cross threading.
Using a torque wrench on the outer nut tighten.

Are the bolts also welded on? If memory serves, it's usually the nuts you remove and these do look welded for some odd reason. You will need to cut/drill and get new bolts.

Good afternoon, sir. I am looking to also change the gaskets. I know that I will need 2 of those. Will you be able to also provide an EOM part number for those, please? Tbis is my first Warrior and the very first bike I am trying to work on myself and I don't want to order the wrong part. Thank you in advance!

Hello. Are these the self-locking nuts? I will be replacing my stock exhaust to a Speedster as well as all of the nuts, bolts stud and bolts, because the ones I currently jave are very rusty. As I watch a few videos on how to take the stock exhaust off the bike and reading your post, I realize that I will he needing the self-locking nuts in order to remove and replace the front head exhaust studs. But looking at these nuts, I don't see the teeth that will grab on each other. Will I have to purchase those self-locking nuts separately?

No, use the old nuts and tighten together tightly towards eachother on the stud. That's how they lock together.
Use the same old nuts to install the new studs.
You don't need different locking style nuts.

The nuts you buy are only to replace the old ones when you go to install your exhaust.

Yes. Get new ones.

I'm saying to use the old nuts to remove the old studs if you will be replacing the old studs aswell.
