What the heck am I doing wrong?
« on: August 07, 2009, 11:52:07 AM »
I'll admit I'm a newbie at this, and I need some expert help. I'm putting a new exhaust on my '74 CB550 and it doesn't seem to be fitting right. The left side extends out so far that the center stand hits the exhaust and won't come all the way up. Here are some pics:


This is how far it comes up



Rear view showing the misalignment between the center stand and its stop



Here's where it hits on the exhaust



Rear brackets



Closer look



Rear view



The frame looks straight, the exhaust support doesn't appear to be bent... the exhaust seems to be too far out by a couple of inches, but the two pipes seem to be aligned ok with each other. The rear brackets are both marked "L", so I'm assuming they go on the left side. And the bottom pipe runs behind the kickstand.

What the heck have I done wrong?

He has the brackets installed correctly.  The link that Schmthaus posted is most likely the answer to this problem.  Also, it's the correct exhaust.  The part number starts with HMCB500, but that doesn't mean its wrong for the 550.

Thanks for the tip; I'd seen that thread during my search before I posted, which is why I mentioned in the OP that the bottom (inside) pipe ran behind the kickstand.



It runs close to the frame just behind the kickstand, but I can't seem to get it any farther away because the rear bracket holds it in position.

So, I loosened up the joint at the head on #2 exhaust and moved the pipe over until it nearly touched the filter housing with no effect to the rear mount orientation; still too far out and interfering with the centerstand. Is it possible that the exhaust mounting "ear" at the rear of the frame could be bent outwards? Just can't figure out what is wrong and the whole project has come to a screeching halt because of this SNAFU. Any ideas?

The pipes seem to be aligned OK, the tube things are lined up. There's some sort of rubbery thing that joins the two mufflers there, correct?
I recall the mufflers being staggered more when viewed from behind, suggesting the bracket should be angled in towards the wheel more. I would try loosening the top bolt and angling the bracket in so the rubber stand stop bumper is horizontal (it's angled out in the pics). If that looks OK I'd bend the bracket and bolt it up.

Bending the bracket would bring it in closer, but I'd like to avoid that, if possible; Honda designed the brackets to fit without bending, so I'm thinking if I have to do something that drastic than there must be something else wrong? Could someone post a pic of their setup so I can compare?

hey m8, dont want to make an obvious comment, or take the piss, but it looks like the centre stand has seen better days on the end, so has it been down the road?, cos it looks bent, and the end has wear marks on it. would it be worth removing the centre stand, and heating and bending the offending foot mount down and out a bit to clear the pipes? if the pipes are ment to fit and they dont, and with the damage on the end of the centre stand, i would probably look at the actual centre stand.

hope this helps.

PS those pipes look bloody awesome!!!!!

with the damage on the end of the centre stand... it looks bent

Not sure what you mean by the "damage to the end"? Guess I thought that's the way it should look. Here are some closeups of the centerstand:







Does it look bent? Are you talking about the leg or the foot extension? Or both? The end of the foot extension definitely looks boogered up to me; the bike looked like it had been laid down a couple of times when I got it. Should there be less of an angle in the extension? Does the foot or the extension rest on the stop when the centerstand is fully retracted?

What I really need is a couple  pictures; one of the centerstand and one preferably from this angle:



so I can do some comparisons.

There are more pictures of this bike on the thread posted above. I've been working on this project for over three years and it's come down to starting it up for the first time but I need the exhaust installed and, well, here we are. I guess you can understand why I am anxious to solve this conundrum.

Thanks for all the suggestions so far.

Thanks for all of your answers. After searching the 'net for CB550 images, and from the input I've gotten here I'm pretty well convinced that the center stand is the culprit. Just my luck that my local motorcycle junkyard isn't open 'til Tuesday. I'll re-post after further developments, er, develope.

Us novices are at the mercy of fate. I wouldn't have known what to look for without the help of everyone here. The center stand looks ok to me, but what do I know? Thanks again for all the help!

Well, some time has passed, and there have been some new developments, as I promised. I went down to the local MC junkyard and picked up a good, used CS for fifteen bucks and installed it on the bike. Here's a comparison with the old and new; you can see how the tang on the old stand has been bent at its joint with the foot, possibly in the same accident that ground the tip off:



Another comparison. You can see the damage to the old stand with the "new" one beside it. I'd noticed before that there were some problems here, but I hadn't realized they were so extensive. Being new to these bikes, I just didn't know what to look for. Thanks to cben750f1 for pointing this out to me ("G'day, mate!")...





So, I installed the new centerstand on the bike and it still didn't fit. The tang still hit the muffler and the Centerstand rest on the muffler wasn't even close to touching the foot. I knew there was nothing wrong with this new stand; I had made comparisons with several others at the junkyard and it was the best I could find.  So I pulled the CS off and, with the help of a friend, bent the lift tang until it no longer hit the muffler. I also noticed that the Centerstand rest on the muffler itself hadn't been positioned correctly before it was tacked into place, so I bent it into position and installed the rubber stop pad. Now when I retract the stand, the foot at least rests on a very thin sliver of the pad while, due to my man-handling, the lift tang no longer touches the muffler:



From the looks of things, judging by the CS pad dislocation and the difficulty encountered during installation, the left side mufflers are being held a good inch to inch-and-a-half too far outboard. I believe that the exhaust has been installed correctly; that is, that all the pipes are routed correctly and brackets are in place per spec. I started looking at the muffler support "ear" on the frame. That's when I noticed this:



I'll admit that I am no expert, and I don't have another frame to compare with, but it looks as though the down tube has been bent forwards just above the frame gusset, creasing the tube at that spot; that is, it appears that the "ear" has been forced forwards and outwards, twisting the down tube in the process. I'm guessing that it could have happened by the passenger peg getting hit from behind, or the bike could have been laid down and somehow skidded backwards on the peg? You can see where the down tube has bulged out where it appears to be bent. The following ultra-saturated images might help point out the apparent damage:






Am I guessing right here? I believe this tube is supposed to be straight and smooth here with no purposeful indentations for the weld; is that correct? If this is true, and this is damage to the frame, it would explain why the mufflers are being such a pain in my freakin' a$$ on this side. On the other side, the right side, the exhaust slid in just like it had been, well, made for it (which it had, of course, being original Honda parts. This is what's known as sarcasm in the face of mounting frustration). On this side, the left, it's been a fight every step of the way and, while I managed to get the mufflers installed, they're under so much tension that they're like two big springs just waiting to go off.


So, what do you think? Do I need a new frame? I'm not sure how much this affects the overall symmetry of the bike; could this cause the frame to be twisted to the point of being unusable? Or is this something I don't need to worry about? Not sure about any of this, and any help will be very much appreciated.

Oh, and here's a pic of the bike as it now stands. I went to turn the engine over one night and the starter button simply sank into the switch housing. I opened it up and the starter switch fell out into my hands in a dozen pieces, the victim of 33 years of exposure to the elements . Needless to say, I'm currently waiting on a new switch


Once again, any suggestions, remarks, observations or questions are welcome.

Here's what mine looks like.

Being bent where yours is could mean that the top shock mounting studs aren't in alignment anymore, and could be an indicator of other frame damage somewhere else.  I would say it definitely warrants a very close inspection of the rest of the frame.

Where are you located?

CL usually has junked 550's for cheap, and salvage yards of course. 

BTW, where did you get your engine case guards?

I live in a small Colorado town about half way between Denver and Fort Collins called Frederick. The Denver Craigslist lists two 550s for sale: one is a cafe racer they're asking $3000 for, the other is a "1973 cb550" with no title for $450. But Craigslist is definitely a source to keep an eye on.

I have been going to two local MC junkyards, and none of their frames have titles, or so they say. And titling an untitled vehicle in Colorado has been made as painful as is humanly possible to accomplish. After you fill out five forms (several in triplicate!), have the police verify the VIN, have an auto dealer make an appraisal, and purchase a surety bond, you've shelled out somewhere just shy of $500. And then, if you've reconstructed a bike from salvage parts, you must stamp, somewhere on the frame that is visible, "Rebuilt From Salvage", and submit receipts for all of the additional parts you purchased to create a roadworthy bike from the salvage!!!

No, I don't think I'll be attempting that soon.

I guess I'll post here in the parts wanted section and keep an eye out on Craigslist. Gotta say, this sucks!!

And thanks for the comment about the build. Figures I'd get it this far before discovering this. All I needed to do was mount the tank and seat and it was done. Bother!

The guards show up on E-bay from time-to-time. Just gotta keep watching.

Hello SohRon, I'm in Fort Collins.  Definitely keep an eye out on CL.  I've seen two 550 frames come up on CL with titles in the $100 range since April.  I was ready to buy one but lost out to someone else as it was in Denver.  I'm currrently in the process of re-titling a '75 CB550F so I know of what you speak.

Bummer about the frame damage.

Thanks for the offers of help, guys. Although the damage is bad enough to scrap the frame for this particular project, I'm not sure it's so bad that I can't just go ahead and finish up and use the bike (carefully) while I'm waiting to buy and restore the new frame. It was never really meant to be a daily driver, so it will most likely see very little use, anyway. Then this winter I'll tear it back down and swap frames.
