Getting the bung part of crash bungs off?

Hi I have R + G crash bungs on my 2003 SV 650. I dropped it last week and bent the left hand bung. I'm replacing them with some Motosliders bungs in the next 2-3 weeks. In the meantime I want to take the R+G bungs off as it looks a little bit shit with a bent left bung.

I didn't fit the bungs myself so I don't know how exactly they fit. I'm aware that there is a bolt that goes through the frame and right through the engine to the other side. I'm also aware that I shouldn't remove this bolt so there is nothing left there and ride around. So because I didn't fit them and don't have the original bolt I need to leave this bolt in.

So I essentially just want to take the external rubber bungs off. How hard is this to do? I'm only just building up my tool collection, will I need a torgue wrench to do this?

Can anyone tell me which bolts I need to be playing with to just take the rubber bungs off and leave the main bolt asssembly through the engine for the time being? I've attached a photo of them below

I've labelled the 3 bolts A, B, and C on the damaged side. B is down the tube of the bung so I'm not quite sure how I'd actually get to that one? But any help over what to leave and what to undo to get the actual rubber bungs off would be much appreciated!

Thankyou![/img]

Bolt C looks like the engine mount bolt, so make sure you leave that in place if you don't have the original mounting bolt.

You could try a socket set to unto the nut that holds the bung on, but since it's bent, you may need to take a saw to it (and a lot of patience).

Hi, As I said on SV650.org, just take the bolt out of the middle of the bung... Now you have put a pic up I can see how this would look difficult but really all you need to do is put a 17mm socket on a extension down the hole in the middle of the bung and undo it with a ratchet, 3/8" drive stuff should do.

If you don't have such things then I would advise you to get Halfords Professional tools, they're not overly expensive, well made and have a lifetime guarantee (if you do brake one just take it back and they replace it no questions asked)

Once it's off clamp the threaded part in a vice and either straighten it or chop it off with a hacksaw, either way DO NOT RE-USE THAT BOLT! it will be very weak where it has bent.

1st thing. You twit! For dropping it. Smile

(I dropped mine in a petrol station whilst checking the tyres pressures. ) Embarassed

The bung can be cut off the bolt but you would then have a big thing sticking out which would be a definite tug and fine under Road Traffic Law : Construction and Use. They will then be able to remove your trousers and have a root around up there too.

Looking at the pic it looks like you could simply grip the outer plastic bung and unscrew from the mounting bracket. I am guessing the mounting bracket has a 10mm threaded hole which the bung bolt screws into.

If that is the case then simply remove the bung as said.

You don't need a torque wrench to remove things. (Normally) Normally you need a torque wrench during assembly.
For fitting bungs or anything to a stressed member then a torque wrench should be used Though there are a load of folk on here who 'know better'.

The R&G website has installation instructions easily available for download.
Personally I'd leave it there. What happens if you drop it before you get the new sliders? Might also be worth a call to R&G they can supply just the bits you need rather than buying a whole new set for more $.

What I would do is take a trip to B&Q and replace the bolt, I've not had mine fitted long so seeing this thread pop up inspired me to go and re-check the bolts (SV's vibrate a lot)

Anyhow, I took the left bung off and took some piccys so you will have a better idea what you are dealing with here.

The bolt is a M10 x 90mm with a plain shank and approx 30mm of thread, The tools I used were a wobble head 3/8 ratchet and 17mm deep socket. Handy as that ratchet is it is not a cheap one (about £90, it's Snap-On, nuff said)

Thanks Stonesie, those pictures are really helpful. I think I'll go for that option for the time being then and just replace the bolt. At some point I want to get Motosliders though, from what I've heard theyre a better bung and much less likely to bend. Cheers!

What's the problem with it bending?

If it saved your bike from damage, and in bending it didn't cause any damage to the frame/mounting points. then it did it's job perfectly. Had it not bent, it may have put more pressure on the mounting points and damaged your frame, which would have been game over.

Crash bungs aren't necessarily a multi-use item (and you certainly shouldn't see them as one). Though all you need to fix that one is a new bolt.

R&Gs are generally considered to be as good, and usually better, than anything else.
