Got the engine guards on, started in on the rack and hit a minor snag.
This is a Givi rack. Looks nice and should fit well.

I see that I need to drop the shocks (undo the top of the shock so it can drop out of the way of the rack).
I can move the bolts with the wrench so that shouldn't be any issue. I'm assuming, I just need to unscrew them and it'll be a no muss-no fuss thing. (If anyone knows differently, give a shout).

My problem are the bolts attaching the small assembly the rear pegs are on. Short of a breaker bar, I'm flummoxed how to get them off. Tried by hand, tried with a drill. It's not moving. Is this typical? It's not something odd like they're reverse threaded and I've been trying to tighten them?

Here's a pic of the two problem children. The two on the other side are just as tight.

Based on the Givi instructions, it looks like I need to get these out so I can attach the rack to this area with the Givi bolts.

IIRC the top of the shock mounts over a frame post and a small bolt threads into the post that just keeps the shock from coming off laterally.

It's easy to remove the bolt, but if you remove the shock from the post you may want to support things first though it might not move much if just one side is removed at a time.

Ah, good to know. I hadn't thought about doing one side at a time. So the shocks are bearing some weight? Under tension at rest? (Not visualizing what might shift if I did both at the same time)

Yes the shocks support the rear of the bike holding the frame above the swing arm/tire.

If you removed both you might have trouble raising that up again to align and install the shocks unless you raised the bike allowing the suspension to drop down.

I'm trying to figure out the rest but I'm not seeing how those bolts fit in? Are we talking about a luggage rack like this one:

Or do you mean a side case rack?!?

Rhodan · « **Reply #4 on:** March 29, 2019, 04:10:27 PM »

Yup, that's exactly the one. Let me take a picture of the installation instructions and it'll be clearer.
The rack has very long arms on each side which reach forward.

The rear rack, yes, you have to remove those two allens. There's no nut behind 'em, so you just have to use brute force to get 'em out. (You probably could squirt some penetrating oil in to help, but I didn't have to)

Do you have a center stand? Using that will take the weight off of the wheel.

It looks like #4 on the installation instructions is where those two existing bolts are. (and thanks for the explanation on the shocks)

Yeah, I do. Good point.

The bolts shouldn't be rusted since I just picked it up about 30 days ago. I can believe pneumatic tools were involved though. OK. Brute force it is. Thanks.

The pictures you have shown are of the muffler/passenger peg hanger. As Kev m described, the upper shock attaching point is @ the top frame rail, just below the seat. I've an MG tail rack on a 3 series Racer. It attaches @ the top, rear shock mount on the frame; both sides.
If you must remove the 2 bolts from the muffler/passenger peg hanger for your project bear in mind those 4 bolts (L&R sides) may have been Loctited (red), @ the factory. Mine were. A fine pointed torch flame, carefully applied to the centers of the socket head allen screws may be the best approach. Alternately a soldering 'gun' may work.
BTW: My adjustable pegs, both axle nuts and all exhaust clamps had red Loctite on them. R3~

Yeah I downloaded and looked at the GIVI instructions, their reach mounts to the fender bolt at rear and those bolts up front.

I like the soldering iron idea.

Red loctite explains why others have found them so tight.

I can't remember for sure if I put the washers on they way they Givi shows them in the picture, but I think I did.

On thing that annoyed me a bit about the rack is that Givi doesn't supply the fancy covers or maybe even a washer for the allens that hold the the shocks on. The little buggers are expensive (over $30 delivered, I think). I got a set from AF-1.

Exactly! Just follow the rear shocks from the bottom all the way to the top. You shouldn't get lost.

Rhodan · « **Reply #12 on:** March 29, 2019, 05:04:38 PM »

Ah. Red Loctite. Yeah, that'd do it.
Thanks all for the info and tips. I don't have a torch but I'm pretty sure I have a soldering gun lying around the garage. We'll see how it goes.

Here's a video on the torch method but down in the comments it discusses the soldering iron/gun approach as well.

Interesting that you have torx head bolts in your passenger footpegs, the earlier V7s all seem to have socket head bolts. These have been known to come loose with use, eventually. Torx heads appear to be more common in the U.S. (& with Harley). I was wondering if some torx afficianado thought these might work better, especially with a drop of locktite. What about other V7 IIIs? I'll check when I get to the shop next.

This is a left-over 2017 if it matters.

Kiwi Dave · « **Reply #15 on:** March 29, 2019, 05:41:32 PM »

My V7 Stone has the torx bolt securing on the passenger footpegs brackets. Seems a little overkill to me, perhaps an allen head bolt came loose one time, and somebody got sued?

Kev m · « **Reply #16 on:** March 29, 2019, 05:45:23 PM »

I was told by a mechanical engineer in the automotive industry that Torx head bolts work better with automated build processes. Not sure if that might be in play here or they just got a better deal on a lot of them. < shrugs >

Roebling3 · « **Reply #17 on:** March 30, 2019, 10:20:25 AM »

I'm curious now about a possible variation in bolt shear strength. Might that be why the Torx version was/is being used.
With no usage of the tail rack one side sheared.
In the original purpose (shock location), that (4mm?), had zero shear stress. Plus those bolts were stainless and will easily shear. R3~

I cheated and had the dealer do it. Couldn't find my soldering iron and had stuff I needed to do yesterday. The dealer put the torx (or other torx) back on rather than using the givi supplied hex heads.

Aesthetically, it's a little longer than I wanted but practically (as a potential base for a top box) it's likely spot on. Very sturdy. Appears to be good quality/good finish.

The pic from my phone doesn't want to upload. I'll do it later from the computer.
