Broken Exhaust Bolts

Having more troubles with an Aprilia SR50 DITECH.

Found out the other day that the tyre has a punchture Sad

didn't think it would be a problem just whip the wheel off and get it sorted. that was untill I found out the exhaust has to be removed.

It turned out that both bolts were very badly rusted and had seized Sad

to make it wose one attachment was a bolt and the other a nut on a stud.

To make it even better the nut on the stud has been completely rounded off at some point Crying or Very sad

When i attempted to remove the siezed bolt that did have a head the bloody thing just broke straight away Crying or Very sad

(bloody Aprilia)

so now I have a scoot with a flat tyre, a rounded zorst nut and broken bolt... how much worse can it get?

my main question is how long is it likely going to take a mechanic to sort this f**kin mess out? as far as i can see the break happened just above the exhaust manifold mount. whats the process for sorting that one out?

Looks like im gonna have to take my sister too collage until the cursed bike is sorted.
note to self... never buy Aprilia.... ever Wink

If the zorst is bust, buy a new one, if the mounts(pegs) with the thread on are bust, the the head off, barrel out and have the port re-threaded. AFAIK, Tis the only way, or get a new barrel bit with good threads already on it. Thumbs Up

Depending on how much is showing of the stud it might possible to remove the stud with the use of an extractor, give the area a good long soaking with WD40 or something similar or if you have the means to heat up the stud before trying to remove it , can you put a picture up so i can see how much is showing.

thanks for the replies Thumbs Up

im inclined to leave this disaster with the mechanic i use as he will be a bit more competent sorting this out.
the exhaust is in good condition, a little corrosion but nothing to justify a replacement.

will soak the area in WD40. im pretty sure when the mech has ago at the rounded nut he will have the same outcome.

Does a bust stud on the exhaust manifold mean that the head is going to have to come off to sort it?

im hoping a stud extractor will sort this mess out Praying

the only trouble with that, IIRC from my old ped, was once you put a bolt, stud with tight nut in, the aluminium used for the head block area is soft, so the threads that hold the initial studs in won't take the strain of being played about with, that was what I was told at the time anyway. Thumbs Up

The head shouldn't have to come off providing there is a bit of stud showing.

When I snapped a stud off in my engine block, there was about 2mm of stud showing. So I got a bolt with the same thread as the remaining stud. Screwed it onto the stud finger tight. Then Filled the inside of the Nut with Weld.

Once it cooled, I heated up the part of the block where the stud was screw`d into, And slowly worked the stud out.

Once both studs were out, I put a thread cleaner down each hole. Bit of copper slip, And 2 new studs were fitted.

Problem solved. Smile

Good luck mate
