Another airbox question - cb550
« on: January 09, 2019, 12:05:33 pm »
I recently made a post about searching for an airbox assembly for a 1978 cb550k and got some really helpful replies. I ended up getting what I needed, or rather most of what I needed, from an ebay listing that someone linked in my last post. The assembly arrived today and after looking over a parts diagram I realized there are some missing parts. So, I have a few questions: Which of these parts are actually necessary/will affect performance? How hard would it be to find these parts on their own? And depending on the answers to the first two, would I be able to craft something to replace these parts? I should also mention that I'm trying to restore the cycle to stock as much as possible.

Here is a diagram with the parts outlined that I'm missing (I've also attached the image as a file):


This is a list of the parts I believe that I'm missing along with part numbers:
#3 Stay A, air cleaner cover - 17214-390-000
#4 Stay B, air cleaner cover - 17215-390-000
#5 Spring, air cleaner element - 17216-323-020
#6 Nut, air cleaner cover x2 - 17216-390-000
#7 Cover, air cleaner - 17220-390-000
#8 Rubber, air cleaner housing seal - 17221-390-300
#9 Duct, air cleaner in. - 17240-390-000
#10 Net, in duct - 17242-390-640
#13 Housing, air cleaner element seal - 17313-390-780
#23 Piece, air cleaner joint - 17359-374-000

I've tried searching for these parts online, but none of the parts websites seem to carry any of these. Which is why I decided to make this post. I've also checked ebay, but I may just be really bad at searching for these types of things.

I appreciate any and all advice!

Are you going to use the stock 4 to 4 exhaust?

If not, you can expand your top cover search to the F models, which have that curved top horn, but not the plate restrictor insert at the mouth.  Tuning with this will be easier if not using the stock exhaust.

The filter spring and small elbow for the recirculator tubes is the same for all the 550s.

Yeah, I thought maybe you'd only want to sell yours as a whole, but what's outlined in the diagram is actually all I need. I also need the stays and nuts to fasten the cover (#3,4, and 6). All together: #5 filter spring, #7 cover, #8 seal, #9 duct, #10 net, and #23 elbow joint. Maybe a clip or two (#1) if you got them. So if you're willing to sell me those pieces, that would be great. Just let me know. And I'm not really that worried about the shipping, unless it's like over $30.

Thanks!
