Morning,

Bike makes a great noise this morning, upon further investigation the retaining ring that clamps one of the down tubes to the head has rusted away, it is no longer connected to the head.

This had been on the cards for a couple of years, the retaining rings and nuts had lost their shape to rust and removing / replacing looked like a new head. I don't imagine the studs look any better.

Does anybody have any clever / cheap ideas as to how to fix the down tube in place ? It is an inline 4 so lock wire it to the ones either side is a possibility ?

A new bike is the sensible solution, but where is the fun in that !!

Thanks

Del

You're talking about fabricating a bracket that can slip over the exhaust without removing the downpipes, and still maintain the seal on the head?

I can't picture what the solution would be to that. Standard lockwire won't be near strong enough, and even if you can bodge it, I would think the heat cycles and vibration will kill off any improvised solution unless you can design and fabricate something fairly clever, from a suitable material. The reality is as well, if one has failed, the others will not be far behind.

I think this is one of those situations where you just bite the bullet and get some new downpipes mate. By the time you've faffed around with a crap solution you could have just replaced with a cheap chinese pattern part and some new exhaust studs/nuts.

Agree with the above, new downpipes look like the best option.

Are we talking about the 4 flanges at the end of the manifold?

One has rusted away and fell of leaving one line blowing.

A split backing flange would do the job, but you'd have to get it is specially made up. Without photos though I'm struggling.

Something like this might fix it if there is any thread left on the studs, lots of different sizes available

If the studs are knackered its head off time.

For those of yous wondering what me and Prolapse are talking about, here's the in joke.....

A alleged colleague may or may not be drinking two bottles of frosty jack at work every day, hiding them in spools then tosing the empty in the adjacent burn. All hearsay of course.



I joked one day about the work getting a call about a blockage down stream from pished beavers building a damm out of empties.

Imagine the hilarity when SEPA showed up as there was a blockage at the screen down the stream..... A warning may or may have not been issued to the company for fly tipping if it wasn't cleaned up.

It was blamed on neds by one employee, he found paw prints and marijuana roaches outside. Big bding dug pished and stoned pawing about the place flinging it's empty in the burn of a night.

I supervised operation blue bottle clear up.



I had about 160 in the sweep stake. Sadly I lost when over 200 were recovered.



I still feel it's a wild witch hunt obviously..... People are blaming a resident in the surround houses as the litter lout. Sadly you'd have to be living next to steve backley to make the burn with your empty from the houses.

Thank you gentlemen.

That is exactly the problem, the little bracket should work, if there is any stud left....
