New exhaust

[Alexx]

Hi guys,so i have a 2013 Kawasaki Er6f and i was thinking of changing the exhaust so after some research i found a full system exhaust from Delkevic that sounds really nice.But here comes my problem,my studs are pretty rusted and because of that the chap from the garage said that normally this will be 1-2 hours job but being that rusted it could snap and then it can turn to a few hundreds pounds more.

I really don’t know if I should risk it,I really like the sound of this Delkevic system but on the other hand I can’t pay that much if things goes south.

What is your thoughts on this ?

remember if its already rusty the longer you leave it the worse it will get  and likely more expensive

When working exhaust studs expect the worst.

 

Anything else is then a bonus. 

 

Personally speaking I tend to work on the basis of...If it ain't broke don't break it. 

 

If you decide to go for it soak the exhaust fittings in copious amounts a penetrating fluid in advance. There a numerous videos on YouTube showing various tricks with corroded fittings. I used to rebuild 1970s cars which threw up loads of seized fixings. Plusgas works very well. When it didn't do the job then a second application of Plusgas immediately followed by WD40 usually did the trick.  Very rarely did I need to use heat or melted wax.

In my experience, patience is the key. Over a number of days, I would heat cycle the studs and add penetrating fluid. I’ve had success with Plusgas and also with a 50/50 mix of ATF and Acetone.

 

But do it lots of times and over a number of days.

 

My other advice would be to not do the actual loosening yourself if you don’t have experience and want to minimise the likelihood of a big bill. It’s an art not a science and you definitely learn to ‘feel’ what’s happening when trying to loosen. I’m no expert but I improve every time I do it.
 

Part of the art is knowing when to try tightening instead of loosening. Also, after the first tiny movement, more penetrant and then a further delay can be a good idea.

 

Sadly, there’s no guarantee of success.

Unfortunately I have zero experience experience in bikes mechanics so It s probably wiser not to try something myself.Friday I will go to the garage to fit a new front tyre and they said they will have a closer look and we’ll take it from there.What is certain is if decide to start the job there is no turning back,I will have to expect the worse.

Well at the moment is there really a need and a rush to do it?

You’ve just paid for a tyre.

Do the studs look like they are going to fail? Is the exhaust going to fail for the next year?

if no then don’t bother just think about it next year And save up for if it based does need more work, if not then great that money will go towards a rear tyre. 
In the meantime between rides you could try to clean the corrosion and soak the studs and protect them yourself from further damage until you really want/have to.

I can’t say that its a priority at the moment it s more let’s say a upgrade that I m planning to do to the bike.On the other side that rust its not gonna go away so let s say I change the exhaust system in the future but what do I clean those studs,is it still a complicated job ?

[Alexx]

Just came back from the garage,I changed the front tyre but regarding the exhaust is not looking good.They said that it can be done but 100% it’s gonna snap so that means expensive job,about 4-5 hours.

So at this point I’m putting this on hold because the labour is costing more than the exhaust system,I could get a second opinion from another garage but i doubt there will be a diferent outcome.
