Frame bolt RE + RE, torque spec, Givi crash bar installation

Hi All,

I searched all over but I'm coming up short on details. I settled down this morning to install the GIVI crash bars on my 2017 DL650. The bars bolt to the wide 'V' shaped frame piece that sits just under the large sloping frame pieces. I stopped out of fear of screwing something up, and came looking for info. Nothing I could find, so I'm coming, hat and wrench in hand, to the group.

The bolts are 6 mm allen/ hex bolts. I realized that a conventional allen key and extension bar is not the correct way to go at this, so I'm going to get hex sockets for my torque wrench.

The factory bolts come out and get replaced with the GIVI bolts. Fine.

So, any guidance about the removal and reinstall of these bolts? How best to remove them... heat first to break the thread locker that is clearly there?

Should I do one at at time or the front RE +RE then the rear?

Do these bolts hold the engine up? (gulp)

Do I have to support the engine from below?

Any idea what the correct torque values are for these bolts? Can't find this anywhere.

I see this as a relatively simple installation, but there are not details at all in the instructions, and I'd really rather not screw up a new bike.

I'll add the Ravetech skid plate after and I will use a dab of thread locker.

Thanks in advance for the help.

I'm having an adventure- so, its an adventure bike.
Now that summer is here, I'm retiring so I can ride full time.

Great idea.

Yes. Longer cap screws (bolts) to ensure standard depth into the thread.

Just undo them with socket and ratchet. Or Hex key.

Should I do one at at time or the front RE +RE then the rear?
Do ONE side at a time - see below.

YES. Do one side at a time. It is unnecessary, but if in doubt support the engine if you wish.

Do I have to support the engine from below?
If you want to. I didn't.

The DL650 manual quotes 40 lbf-ft (55Nm) for engine mounting bolts.

@Brockie

Thanks for the reply. I think that getting the hex head socket will be an important step; right tool for the job, as they say. I don't know if these bolts are the same as engine mounting bolts, but that is probably a good reference setting for these frame attachments.

They are the engine mounting bolts. They attach the V-shaped bracket (which holds much of the engine weight) to the beam frame. A little blue Loctite would be good. Another trooper here recently talked of a vibration which ended up being these bolts coming loose after he had fitted crash bars.
Take your time. One side at a time.

Thanks again. That makes sense, that the V pieces support / attach the engine to the beam frame- I appreciate that info. I'm not anxious to have the engine get any ideas about making a break for freedom.

I will certainly do this work slowly and carefully, with a calm mind, clear schedule and no beer in hand. I have blue loctite and will definitely use it. Might also enlist the help of a more knowledgable friend.

Or, would you suggest getting an actual competent mechanic to do this work? If so, I'm willing to go that route instead of making it a home install.

Thanks again.

Take your time and you will do fine. If you want to weaken the bond of the factory thread locker use a bit of heat on the bolt. A soldering iron or gun works well. Put the tip in the hex recess and heat her up. Consider how hot the bolt gets from engine heat and get it hotter than that. Mount one side but don't fully tighten down. Then mount the other and join together. The bit of play will help with alignment of the front piece if the bends are not perfect. Tourque every thing up. Put a witness mark at 12 oclock on the bolts heads. For the next while before you ride have a look see at the marks. No movement, all good. If the ice and sand were off the passes I would ride down and assist. Need to make it down to the coast and see some grass and flowers ha ha

Thank @BC Rider

Very much appreciate the post. I will add your guidance to the process. Marks to check alignment was something I was also planning on.

Beautiful weather here, finally! Went out yesterday and I'm planning on doing all my work commuting on the bikes as often as I can. I'll also be in the OK this summer; I have friends with a place in Summerland and a friend's band is doing a bit of tour in the south OK, so I'll have that on the agenda.

So great having a world-wide, and local, group of friends to help!

Still clouds of salty dust here on the roads. Bike is still stashed in the garage with 8 inches of snow in front. You will enjoy the summer heat up here. Hoping for no forest fires this year.

Well, this must not be my day for amateur mechanics. Even being careful, I've striped one of the allen bolts on the V support. Shit. It is not totally ruined, but it is not working with an allen head socket. I used heat, and really thought I had it all the way in. But apparently not.

Some sort of stripped bolt remover must be available. Problem is, the bolt is recessed into the frame. At least the bars come with replacement bolts. The factory bolts do seem soft.

Impact driver did not help (the kind you hit with a hammer) but I was not too brutal. Drill and easy out is next step, I think.

Any advice before I do more damage?

Well hell eh. Before doing anything heat soak it again, enough to break the thread locker. Hard spot to dremel a slot to use a large flat head in the impact. Either weld allan key into it or JB weld the allen socket into it. Have the epoxy take up the missing metal. Let it cure very well. Be very careful if you drill and extract. Look at your new bolts to judge the drill size. Leave enough meat for the extractor to bite into. Myself I hate using extractors as they seem to snap so easily now a days.
