HarleyTim, what is the torque to spec for the 02 sensors? I do not see the torque spec list in the VH installation instructions.
WideGlideFever, what is this crush gasket you are referring to? I know some cars have the crush gasket on oil drain plugs that "crush" when you tighten the plug up but do not see where Harley or V&H has this for their exhaust.
Thanks for the ideas.

On my installation of V&H "Big Shots" I used electically conductive anti-sieze on the O2 sensors and torqued to spec.
On the flange studs, torque to spec., and after a couple of cool down cycles, torque
again. continue to do this until no movement is detected. Then I put another set of nuts on top of the others to lock them in place.
Works for me....

The crush gaskets are the stock type gaskets for your bike. Due to getting covered with exhaust soot it may look like you don't have gaskets in the head but they are there and you need a pick tool to remove them.

I am still working on getting these darn circlips out of the flange. I am using the snapring pilers as stated in the V&H instruction sheet. But when I use the snapring pliers it it does not see to work because the circlips are not cut straight on the two edges. They are slanting inwards so when you press on the snapring pliers the nose slides down and then off the circlips.
I took my pocket knife and noticed that one end will slide up from the flange. It would look like this would work. Has anyone noticed that the snapring pliers is not working for them?
nevil...now that you mention the heads they are probably on the bike. Will get to that but what about this darn circlips??

BTW...these circlips in the flange do not have holes. I googled and notice someone mentioned theirs do not have holes. Not sure why V&H suggest to buy the snapring pliers but I have used these years ago and normally work with rings that have holes in 'em.
From the looks of it...the circlips in the flange is not set in a groove so they can probably be pushed out.
V&H instructions say to replace bent or damaged circlips. It looks like mine is slightly bent but have no way of knowing until I get it pulled out. It looks bent from when the flange is tighten up.

Yeah that is what I did. Screw those snapring pliers. They were shitty ones anyway and did not work too well.
I found out when going to install the bracket from Vance and Hines that I am missing two screws! They come with three screws, one is long and the other two a little shorter. I did not have the two short screws to mount the bracket. Also I noticed the long screw was more yellow instead of aluminum color.
I emailed the person I talked to at Fuelmoto and will have to place a call on Monday. Not sure if I have to call Vance since FM gets these from Vance and Hines. Well this is how my day goes.
Also the clip I took out of my stock pipe flange were not straignt per se. Laying this clip on the table it was not flat and this is from the torqueing so it was bent a little. I was not sure but ran to HD and got two new ones for less than $4.
While at HD I also got the gasket since I was not sure how it is in my bike. I see the gasket in the cylinder head but did not remove yet but went ahead and bought two. Looking in my bag of parts that came with the V&H Big Shots...they have two gaskets in there but they do not look like what I picked up from HD. Does V&H use a different gasket based on their pipes?
While everything is on hold cuz the bracket is not mounted...I went ahead and removed the stock A/C and in the process of installing the FM Stage 1 A/C...I see the packet came with two gaskets. Is this two gaskets because some bikes are carb and some are FI? Or do we have to use two gaskets when installing the FM?
I can see mounting one gasket between the backplate and throttle body. But where does the other gasket go?

Chances are when your done sliding the new c clips over the flanges they will no longer be flat. I straightened mine with a couple pairs of pliers. Some exhaust flanges have square shoulders and some are tapered (rounded). Exhaust manifold gaskets also come square and tapered. HD gaskets are tapered and screaming eagle ones are square shouldered. If your V&H are square I'd use the Screaming Eagle gaskets.

PS: You need to read both the V & H instructions, and the OE service manual to get the proper torque pattern when tightening down all your bolts.

Although, the shop manual does say to use "Lock-tite", I prefer not to do that. As others have stated, it doesn't seem useful to use lock-tite in high temp applications to me... Just sayin'.
Hope this helps.
