Hey all
I just received a Delkevic Exhaust system with a straight pipe (this one: 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 can't get it to fit though, and Im not sure if it's because I am missing something. The muffler won't fit straight on the head, and when I use the included bracket, I can barely get the muffler to connect with the head (see pictures). Furthermore, when the muffler is connected with the included bracket, the centerstand is not hitting the rubber piece included and mounted on the muffler as well.
Has anyone fitted this system, and can help me with a little guidance?
-
Hang on a minute Alex. Graham's Mongrel has a Delkevic, I'll go and take some photos.
-
Looks like this set will fit the 500 four.
The bracket is too long.
Contact Delcevic with the problem.
-
As said, one system cannot fit all the bikes with only one mounting plate as the footrests are in differen places, if they dont have a different mounting you will have to modify what you have or make one

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?
-
I think where you fit the bracket depends on what frame you have Alex, I think Graham's is a 550K1.
-
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…
-
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.
-
Pretty sure that the bracket needs to go on the outside face of the footrest mount or the bolt head and exhaust mounting bracket will strike the swing arm? I’ve got an F1, but I’m not in a position to take photos until later this afternoon. If Trig doesn’t get round to sending a photo I’ll send one this pm.
-
Photos from Grahams WhatsApp group. This is on a CB550 F1 fitted last week by a forum member.

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!
-
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.
-
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.

Inside ???

I only have mine on the outside as i don't have a footpeg. Mine is a 550K1 which is the same frame as a CB500 four.
-
Just managed to fight my way through the garage to check mine….it’s on the inside of the footrest mount.

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?
-
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!
-
The rubber stop bolts on the back of the bracket and the foot of the center stand rests against it when the center stand is up.
I have fitted a fair few of these exhausts and never had any problems with or with out a center stand fitted. Are you sure that your center stand is not bent or out of shape.
The delkevic pipes come with little stickers numbered 1 to 4 which match the connecting pipe. You fit everything loose to the bike and do not tighten up any nuts or bolts until everything is lined up ;)

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.
-
Take the bracket off, mount the silencer properly and see what needs modifying on the bracket
-
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.
-
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?
-
Nope, all500 plus 550 k0tok2 inclusive are the same, 550k3 and F are different in the passenger footrest mount
-
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.
:( :( :(
-
Delkevic code for the CB550F is COM320B
Delkevic code for the CB550K is HDR000B
CB500 four is the same frame as CB550 K0, K1, K2
CB550F1 frame is the same as a CB550 F2
CB550K3 is different and stands on its own.
Looks as you may of order the wrong one ? What Delkevic part number do you have ? And is the frame stamped with CB550F or CB550K ?
-
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!

Ted, the Dekelvic fits just fine if the correct one is ordered and delivered. The one on my F2 almost fitted itself. Having said that, if you have a 500, I’d be tempted to swallow the additional cost of a replica 4 pipe system as it looks and sounds much nicer on the 500. I was even tempted to fit one to the 550, but it just seemed too radical and I live in hope of finding an original or copy 4:1.

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!

I have always ordered the one for the bike i am fitting it to. The strange thing with the Delkevic site, is if you put in CB500 Four if comes up with part number COM3299 but, HDR000B should be the same fitting for that style of pipes.
I have never measured up different frames to see if there is any difference on the foot peg location. I know Motad used to fit all but, the silencer on the Motad had a big slide adjuster on the silencer to position the bracket .
You will have to email Delkevic, send some pictures of your problem to find the answer

Mmh, I am getting HDR000B for the CB550F, but HDR000A for the CB550K. I wonder what the difference is between those two parts.
I will call them and try and get some answers.
-
I know style & fashion change over the years - I can still remember seeing the four pipe systems on the old Hondas when they were new thinking they looked really dated/old fashioned somehow being so bulbous - not to mention the great asymetric 4 into1 look.
Now 50 years later here I am seriously thinking the 4 pipe look is what I want!
The eye of the beholder eh.😎😎😎
-
4 pipe all the way Ted. You know it makes sense.
-
Definitely makes fiscal sense plus SS too.
-
Not sure if this helps you, but this is what is with a system I bought [attachimg=1] to put on a 550f. Ive since changed my mind and am hoping it will go on the 500 Im currently working on.

Let me know. I don't think it will. For a 500, I think you need the bracket I have received. If all else fails in the communication with Delkevic, we can always switch brackets and rubber stops, as it would seem as if you have gotten the version I need, and I have the version you need :)
-
OK, Sounds like a swop could be in order. I too have emailed Delkevic to ask if I need a different bracket, Ill let you know the outcome.

550F has different frame loops for the rear footrests than the 550K which has the same as the 500K. I seem to recall the frame loops on the 550F had the bolt for the footrests farther back than the 500/550K which looks to be the problem you have with the wrong bracket.
-
A CB500 and a CB550K is 290mm from the bottom rear engine bolt to the footpeg hanger bolt .
The CB550 F1, F2 is 300mm at the same measurement so, 10mm more ;)

Amazing how 10mm can spoil all my plans for riding this summer! :o

Said the actress to the bishop!!!

Also 10mm difference from the top shock mount to the foot peg hanger bolt ;)

Update on this: Delkevic is sending me new brackets and rubber stops that should fit my bike. Will keep you guys posted.
