So, apparently I lost a exhaust nut from the flange and with the vibration it broke the lower stud bolt for my exhaust on my 2010 C5... :( Now I'll need to get the broken one out somehow and get a replacement stud. Just wondering what the size is for the stud? Hopefully I can pick one up locally, I believe it is part # 500339. Any advice/tricks to getting the broken one out? Thanks!

Tim, I broke my lower exhaust bolt about a year ago putting on a new pipe. You can remove it fairly easy enough with an EASY OUT. You drill a small hole carefully in the center of the broken stud, drive in the tool and unscrew the stud. You can buy a small Easy Out set from Harbor Freight or your local auto parts store.
-
Or If you weld or have someone nearby who does, A nut can be welded on the stud, from the inside of the nut. Then taken out with a wrench. The heat of the welder also helps loosen the stud. This is assuming you have it sheared off at the base..... If not, and you can get some vise grips on it. Some heat, tapping on the stud and some back and forth with the vise grips and you should be able to get it out.

Sounds like the easy out is my way of thinking, something about fire and me that don't work well together! :o Now just for the size of that bolt....
-
LOL !.... No problem. I BELIEVE it is a 8mm 1.25 But don't quote me on that. I know the nut for it is a 12mm. I'd have to check that when i get home. If you have a caliper, you can measure the other one.
-
And if it doesn't seem to want to come out a penetrating lube and a little heat help a whole lot. You can use a propane torch to heat the aluminum around the broken stud, or a heat gun for the fire averse ;)

8mmx1.25 is the correct size. i recommend penetrating fluid also.
-
Lots of penetrating fluid and broken drill bits, finally got the bugger out! Now to make sure it doesn't happen again. Thanks for the advice guys!
Now that I have the exhaust off I'm going to change out the sprocket and make some mods to the breather hose! Let the fun (and/or cursing) begin! ;D

+1 Tim !

What's wrong with the breather hose?
My UCE uses a very good oil/air separator that's never given me any trouble at all.
That includes some 200 mile trips where I was running at 65 mph for long distances.

Glad you got it Tim !

Nicely done!

Every so often it'll burp up some oil on my air filter, so I replace it and hope for the best. I hear from other RE riders that it can be altitude, pressure systems, bad karma, etc. that causes it. I'm careful not to fill it up too much, usually just so I can see it in the glass. I put a longer breather hose on it, and duckbilled the hose (I have read the debates on it), so it nearly touches the back of the chain just inside of the chain guard. At least it will oil the chain and not my air filter/leg/exhaust....
I took my RE on a tour for 300km doing about 100km/hr consistently with no oil burping, so I don't get it.... :o

My secret weapon technique for removing broken bolts is a little heat, a shot of P-B Blaster, dremel or punch a little divot in the bolt, dead center to keep the drill bit from wandering and then drill it with a left hand flute drill bit.
More often than not the drill bit will dig in and back the bolt out.
Don't forget to run the drill in reverse.
Left hand drill bits do not cut going forwards. Do not ask me how I know this.

Ha! nice one one ice. ;D ;D ;D
