CB500/550 / Re: Fitting a Delkevic exhaust system on my CB550F 1977
« on: July 24, 2023, 07:07:00 AM »
I have been toying with the idea of fitting the Dekelvic system to my 500 to save money - this is putting me off somewhat - I might have to raid the imaginary gold reserves and fit the original 4 pipe system - a decision possibly for a new fiscal year.
 :( :( :(

Don't be too discouraged Ted. On the .co.uk website, you can choose specifically which model the exhaust is for, and I think this makes sure that you get the correct parts. You can't do that on the US website (where I ordered mine), and in the headline it just says that this fits all of the models, which it obviously doesn't. The exhaust in itself is very well made and looks and sounds really nice!

Ugh, I ordered mine from the US website, where they only have one link and a text that tells the customer this will fit them all (here: https://delkevic.com/full-system-to-fit-cb500-four-1971-1973-cb550-1974-1975-cb550k-1975-1978-cb550f-1975-1977-with-classic-straight-universal-muffler-and-stainless-steel-4-1-downpipes/).

I see now on the UK site that you can select specifically a C550F model and get the part number you are referring to :(

Hopefully the pipes, head and muffler are the exact same, and it is only the bracket that differs!

Also, on the american forum, I found this bike. Obviously this is a 750, but this seems more like the kind of bracket I need. It's reaching backward, therefore allowing the muffler to be attached way more forward on the bike.

750s and CB550F didn't share same frame, did they?

Turn the center stand stop around  ;)

I can't :( Because of the way its designed, it can only go on one way.

Yep sorry about that. I have just found one and i can see what you mean .
Something is not lining up with yours .

This is the same centerstand rubber stop I got with mine. Also the bag for the bracket has the same text (see pictures). But on their website it says that this should fit a CB550F2. Can we agree that a F2 model is not called something with K? Because in that case I feel like I have a pretty good case when I talk to Delkevic.

Hey

Here is some pictures to better explain what's happening. On the first picture, I have mounted the muffler via the bracket that came with the exhaust. It shows clearly how the muffler almost can't connect to the head.

On the second picture, same setup, but this shows how the centerstand is not hitting the rubber stop when the muffler is mounted via the bracket.

Lastly, on the third picture, I tried to slide the head more away from the exhaust pipes, so it sat right in the middle of the exhaust pipe and the muffler (still mounted via the bracket). But that gives such a space between the exhaust pipes and the head, that I will never be able to connect the springs and drag them out. It simply requires too much force.

The last picture is without the muffler, so you can see the condition of the centerstand, which to my knowledge is exactly as it should be.

The pictures Nurse Julie put on is a CB550 F1, which is the same frame, footpeg hanger and set up as a 550F2.

If the silencer is not supported, you run the risk of the exhaust studs being snapped in the head  ;)

The Delkevic should come with a tube of exhaust sealer .

It is indeed, but he has not mounted the centerstand rubber stop. He is using the same bracket as I have, but if using the centerstand, it will not hit the rubber stop, had he mounted it. Also, the muffler must be sitting really far back (see my initial picture, where you can see the position of the muffler when it has to align with the passenger peg hole), so the muffler is barely slid on the head.

At least that's the case on my bike. I would have to slide the head half of the exhaust pipes and then mount the muffler half on the head in the other end. But the whole operation would be rather wiggly as a result. And the centerstand rubber stop would not line up with the actual centerstand :(

And to top it all off, the delkevic didn't come with exhaust sealer. I am going to call them next week for sure!

I found this picture on our american sister forum. Although it is a CB750, the bracket looks more like the type I need to mount it on a CB550F2, as the mounting hole for the passenger peg is shot backwards like that, thus allowing the muffler to be mounted properly, the centerstand rubber stop to still function correctly all the while still being mounted securely.

Two questions:

1. Can I let the muffler hang without the mounting bracket for a while, or will that be too heavy and comprosise the structure of the mounting pegs on the engine block?

2. I have attached the muffler with a tension band that secures with some screws. I feel like I have tightened it tremendously, but when I rev the engine, fluid still seeps out where it is attached. How hard am I supposed to torque these screws on the tension band? Also, do you guys use some sort of gasket goo before attaching the muffler?

It’s a it difficult to tell from those photos, but is the bracket on the inside or outside of the footrest mounting?

To my eyes it’s on the inside.

I think my main concern is that if I mount the muffler with the included bracket to the passenger peg hole, the center stand rubber stop is way to back on the back and is not stopping the center stand, which leads me to believe that I need a different bracket, that will put the muffler forward around 5-10 cm.

Mmh… that bracket looks similar to mine though. I wonder how the rest of his exhaust is mounted and configured. Also it doesn't seem like he is using the center stand stop rubber.

The passenger seat peg as indentations that fit the indentations of the frame. If I mount the exhaust on the outside of the frame, it will interfere with the indentations, which is why I think it is to be mounted on the inner side. But would love to see pictures of how you do it!

Yes, all the brackets that came with the Delkevic, have always has two stainless steel non painted. One for the hanger and one which is the centre stand stop  ;)

Yeah, the center stand stop is stainless. Maybe it's new that they paint the other one.

But the bracket for the hanger has always been the same type, right? I was just thinking if they ship different brackets depending on what CB550 model you are buying for.

All the ones i have fitted have been bare stainless but, that was the early ones when they were half the price. Just spoke to a member on my whatsapp group and he has just fitted a new one to a CB550F1 and the bracket is black on his. I will put some pictures up of his fitted, if he doesn't do it before me.  ;)

Aw man, that would be very helpful with some pictures of their mount on a F1 model! Then I can see of the bracket is different as well.

Your bracket looks to be black. All the Delkevic's i have fitted have had a stainless steel bracket.

I have written Delkevic and asked if they have other bracket options. In all the Delkevic systems you have installed for 550s, is it always the same bracket in the package? Mine came in black as well, but looked official enough…

Yours looks like a different bracket and it's fitted on the wrong side of the footpeg hanger.

Thanks for those pictures Julie! The foot peg bar on that bike seems to be different than mine. It's probably because I have that different setup that it doesn't fit. I will try and email Delkevic and see if they have another proper bracket.

And I think it's supposed to be mounted on the inner side and then the passenger foot peg on the outside, no?
