Exhaust fallen off twice?

[Wilson123]

What the fuck is this

I bought this:

https://www.pmtuning.co.uk/Merchant2/merchant.mvc?Screen=PROD&Store_Code=PT&Product_Code=01-ENTB_503&Category_Code=00214100SPEEDFIGHT

and fitted it on my peugeot speedfight 100, a few hours later it fell off snapping one of the connector pins so I had to buy a new engine basically

So I bought this:

https://www.pmtuning.co.uk/Merchant2/merchant.mvc?Screen=PROD&Store_Code=PT&Product_Code=06-M3111081&Category_Code=00214100SPEEDFIGHT

Now it just fell off again, snapping one of the connectors


Why?

well, to have 2 different thing youve put on, fall off. id say you didnt put them on properly.

[Wilson123]

I didn't put either on, my brother put one on and my dad put the other on.

so how long did it stay on before it fell off?

[Wilson123]

First time about an hour, this time almost 300km

the bolts on the exhaust mount, are they snapping, or falling off, thus causing the exhaust to fall off.
if the bolts are missing after your exhaust comes off, it could be the vibrations of the bike unscrewing the bolt.

[kungfupoodle]

So what happened to the two big bolts holiding it to the bike?

[sickpup]

Pictures would help in this?

[Finglonga]

If the exhaust didin't quite fit properly and the fixings were tightened up under pressure then the whole thing would be under stress. Stress + Vibration = Fracture at weakest point.

Oh and. . . .

[kungfupoodle]

Those pics certainly helped me. I feel so calm now..

The OP put the exhaust back on with the new barrel so probably didn't fracture the mountings.

A dose of thread lock and a torque wrench should do the trick.

And don't let your dad or brother near your bike again - if they knew what they were doing one of them would have figured it out after the first time it fell off

you are supporting the exhaust weight with the hanger arent you, i mean not just hanging the exhaust off the studs on the head?

[the grim reaper]

Are your engine mounts knackered? If the engine was moving in the frame it could cause this type of fracture. Assuming it's a ped, the security of the engine still applies.

Nevermind, I figured out what it is

[Polarbear]

Well tell us then, did your dad put it on upside down or something?

No, my dickhead brother snapped something off when he took my old exhaust, I didn't notice and there's a reason why the connector is triangle, it's supposed to connect at all three sides, I thought it was triangle in case one of them broke off(like both did), I noticed yesterday and what's been happening is because it's only held on by two bolts it's had a slight space to move in causing the weight of the exhaust to snap the triangle connector which leaves all of the weight on the two connecting bolts, that's why they keep snapping and falling out. Facepaaaaaalm

Hope I can fix it like

[kungfupoodle]

I knew it had something to do with letting your family members loose to work on your bike

Good luck cleaning up their mess

[Wilson123]

Thankyou thankyou, might need welding

pu on with a torque wrench !!! you might be putting too much pressure on the bolts, especially as its under pressure taking air from the combustion chamber. its worth having a look at it. you could attach another bracket along the exhaust to take a bit of pressure off those bolts??

and dude, i looked at that photo,, wear some leathers you fool!! could have been much worse

[TUG]

Speed fights are prone to cracking crank cases if the bike falls onto the exhaust side. They have superseeded the part for this making it stronger.
