Long story short, I binned it, Nice dent in the frame from where the crash bung was. Is it possibly to have this repaired? There aren't any stress marks or obvious cracking in the area. The bike still rides dead straight and other than this and the rotor cover cracking, it held up remarkably well...

Normally I'd be in the new frame camp but seeing as this is a low milage 4DX 400 frame, the likely hood of finding another 4DX as apposed to a 3TJ is very slim.

And if anyone has a alternator cover, PM Me Thumbs Up

I'd just leave it as it is personally. Keep an eye on it and consider what to do if you do see a crack developing or similar.

You could easily pull that out with a slide hammer and some heat

slide hammer and heat but it won't be perfect or find a body repair place that has a key weld dent pulling system which will be near perfect but frame will need painting after

This is an example of whether crash bungs are a help or not. Would there have been more damage, but easier to fix without the bungs?

Don't get me wrong, I have them.

I'd either leave it or take it to a repair centre.

If you try yourself, and get it wrong, you'll be cursing yourself for it.

At least you're okay and in the end its just a machine.
Good luck.

You shouldn't work aluminum hot, as at high temperatures it can become brittle. Also, due to thermal conductivity of it, you need quite a bit of heat to get an area hot, but then it's a tiny margin before it becomes too much and lets go. It is beyond the scope of most home equipment and skills.

Heating and attempting to pull out will crack it. You could anneal and then work it, but then you will need to find away to get it up to around 420c then a way to treat it so that it is back to how it should be.

So there you go, that's why it matters that it's aluminum, it's not a material that you can heat and work.

I'd agree with you if it was damage to the cast element.
but it isn't, so I don't.

I'd much rather attempt it after attempting to anneal it rather than cold work a partially hardened member. Aluminium can be re-worked just fine, and some alloys even more so (even though I don't know what alloy this is).

You can get pretty accurate with the heating by using a candle as a gauge.

Looks to be like they are the shitty cheap bungs not something 'proper' an R&G or similar I would have through would have gone through the engine mount.

Thanks for the help guys!

So the overall opinion is that it's safe enough and it could be taken out with a slide hammer? This would be done by a pro, Wouldn't trust a DIY job on a frame.

I would get covers but they are very much a rare item for the 400

As for the crash bung arguement, I think if they were good bungs they would have gone through the mounts and CR said. These were on the bike when i bought it and didn't think anything of them They did save the fairings and pretty much everything else too so you can make up your own mind about them.

Paddy, If you could shoot a couple photos over that would be great! I think the Tcat and the FZR600s are the same but if in doubt i can measure mine Thumbs Up

I'd not worry about that dent, my 750Y had a much bigger one.

ignore it, keep an eye on ebay for a decent frame?

It will probably be more hassle than its worth trying to repair it, and without being insulting, it isnt a show bike.

Think of it as a war wound, or patina of age Smile

Thinking i might have a go at making some carbon frame covers, Might make a tad on the side if they come up good Thumbs Up

Paddy, Had a chance to hunt for the casing yet?
