I thought I saw some stuff in screwfix but canot find it now but i think it was like this http://www.ttproducts.com/freeze-off2.html and this http://www.rimmerbros.co.uk/Item--i-T5WNO400?utm_source=google&utm_medium=cpc&utm_campaign=PLA&gclid=CLW46JPDjsUCFagfwwodiYEApw
I wonder if they would be of use if you can warm the engine and then get around the back of the clamp to try and spray just the stud so the lubricant in the spray gos through the clamp holes to the back of the nut and at the same time shrinks just the stud

Sounds healthy!
Just a thought... when you run the bike up to temperature then just progressively/gently tighten the exhaust header flange nuts to the recommended torque-its only a low figure 8-10 Nm fro memory but check! A 1/4" socket set with extension to clear pipes/frame is ideal. Dont want to go back to square one again

Yep see my reply back one page about that, I would also say do the two bolts together - so not just 1 at 10nm then the other as you will see the clamp pivot down to the one just tightened

I might just leave the all loose and let is scare the neighbours....

shall bit the bullet later tonight or tomorrow depends on time - but it will be a 1/2 a turn on each nut and plenty of patience....I do NOT want a repeat performance...it almost killed me

I did learn a lot

Get some stainless steel dome nuts and you should never have to worry again. If I ever get another bike the first mod I make will be to replace all the nuts/bolts from one end of exhaust to the other with stainless.

WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Well done

now do as above, dome nuts and enjoy the ride!

ajmes1 · « **Reply #133 on:** 03 May 2015, 02:25:22 pm »

running the risk of scowls here, but I just managed to get the old downpipes off with not much stress, and only 24 hours of soaking in wilkos rip off wd40.

Is it worth putting some grease on the gaskets and the studs?

bandit · « **Reply #134 on:** 03 May 2015, 02:37:10 pm »

You can put a little bit of copper grease on the gaskets just to hold them in the ports whilst you align the downpipes into position, apply copper grease to the studs & if using the original nuts after tightening fill the open end with said grease to.

ajmes1 · « **Reply #135 on:** 03 May 2015, 02:39:41 pm »

brill thanks for that, it's on the shopping to list pop and get get now then as only have standard grease!

Jules-C · « **Reply #136 on:** 03 May 2015, 04:24:56 pm »

Even standard bearing grease will be better than nothing

ajmes1 · « **Reply #137 on:** 03 May 2015, 04:42:04 pm »

Brill, as I had to pop out i got some stainless nylock nuts to fit instead, but still gave the studs a really good brush.

Sounds and looks amazing!

davey boy · « **Reply #138 on:** 03 May 2015, 05:38:34 pm »

Just a thought but will the nylon in the nylock nut not melt with the heat

ajmes1 · « **Reply #139 on:** 03 May 2015, 06:50:49 pm »

I hadn't thought of that, bugger.

I'll be looking to change them before long anyway as they were cheap shitty halfrauds nuts to get me on the road. Rounded three off while I was fitting them (luckily managed to get them off).

Will it be much of an issue?

Dave48 · « **Reply #140 on:** 04 May 2015, 07:04:06 am »

What you want,as already suggested, is a set of 8 dome headed stainless steel nuts. If by any chance your studs are too long and make contact with the ends/tops of these then simply fit stainless steel plain washers between the exhaust flanges and the nuts. These nuts will prevent ingress of water/dirt and avoid future problems if you need to remove them again. I definitely wouldnt use nylocs in this application due to the extreme temperatures in this area. Dont forget to use light coating of copper grease on studs.

ajmes1 · « **Reply #141 on:** 04 May 2015, 09:40:47 am »

I'll get some ordered up then =]

Just to confirm the studs are M6 thread aren't they? I just took the nuts out of the pack that fitted (they weren't labelled with sizes!!).

bandit · « **Reply #142 on:** 04 May 2015, 09:51:43 am »

Yes M6 they is!

Thought you'd of painted those engine blocks? you've been slacking anutz

i know .....shameful

Its something i was going to ask as part of my new thread.....i intend to paint up the new engine - so will wait and see - its in a mess

I'm glad to see this got sorted in the end. My exhaust is blowing so the pipes are going to come off. I wasn't planning to do this myself given that I'm hopeless at such things. I was going to ride the bike to a shop but wasn't sure what to do before hand to make this job less risky.
Everything is original on a 2001 bike but seemed to in good condition and under 6k when I bought it. I've done about 4.5k but it has been in a shed over winter I don't know if it's just a gasket it a new down pipe job.

Would it be better to get someone to come to me and not ride it?

anutz · « **Reply #149 on:** 23 May 2015, 10:51:24 pm »

Hi....

Based on what i did, be careful, i was a bit of a fool and did not use the proper techniques.....but even the on my spare engine with a campingaz torch it was not plain sailing...

If you can get some penetrating fluid and give them a good spray a few times a day for a week or so - i have used plusgas on lots of siezed joints

Some careful heating as well on the studs, till they glow red, can help....this can break seals

Also don't do anythnig when its cold, so much easier to snap!

On my spare engine i have actually managed to remove 5 actual studs, not just nuts but studs....but its a spare so i did not care about the fact 3 were buggered...and its a project to re-build...

If you trust the local mechanics and they know what they are doing it might be the best bet to then enusre you can ride it the rest of summmer.....i am still to get out!

Regards not riding it - not sure, i don't see what it would do if it is blowing a little bit....lets see what any one else says, how far do you have to go?
