Topic: Million-dollar 550. Need help with jetting!!!

[firefighter_zach]

Hey guys I need some help. I am putting pod filters and 4-4 high-flow exhaust on my '74 CB 550 and was wondering if anyone else has this setup? I just need a baseline for main jets and needle clip positions as I can fine tune them later.

I got this bike for $411 dollars on eBay locally. It hadn't run in two years and needed attention but it had a title and it was local so with my dads truck on a sunny summer night i took her home!
Ever since then it has been a money pit! I have changed my mind so many times on exactly what style I was goin for. I knew it was going to be a bobber from the start but things look different when you take them out of the box and therefore I have:
2 seats (not including the one that came on the bike)
3 sets of handlebars
2 front wheels
3 sets of seat springs
3 total sets of neck bearings (runnin a harley front end, very very expensive idea)
2 sets of exhaust
most of these are brand new parts that didn't look right when they got home, so they sit in a pile for my future projects

As you can see I have little or no money left (not that its stopping me) and any help especially with jetting would be appreciated!

I would post pics if i knew how, anyone know how to do that easily?

To help a fellow 550 owner out  ... In regards to posting pictures, I use www.imageshack.us  It's really straightforward/intuitive.  Plus, if you sign up (give them your email address and make a password), it keeps all your images in an online gallery for you.  If you want to post images here or elsewhere, you simply select the ones you want in your gallery, click 'get code for forums', then copy everything in that window, and paste it into your 'post' window.

Hope that helps.  If you have any questions, let me know!

Those six letters can immediately triple the cost of just about anything...

The easiest way to add pictures is to attach them to you post. When posting, hit the "Additional Options..." text, then browse and attach pictures. Another good option is to use something like PhotoBucket to host pictures for you, then post them here using image tags:

If you really want to do image hosting right, use DropBox. All you have to do is put pictures in a folder on your computer and they will automatically be uploaded to the internet, and you can link to them anywhere you want. It's what I use.

I have a  '78 550, near sea level, with pods and 4-1; running 105 mains and stock clip position on the needles.

if you want to recoup some $$$'s are any of the seats brattish?  would they fit a CB400F?

Same here, though mine is a 4-2.

Here is what the search engine found for me :

Thanks guys!
I will start with 105 mains and probably one-up on needle clip positions. Hopefully pilot jets will be alright.
OBRUT: The seats I have are solo-style seats like you would see on vintage harley knuckleheads and pans. Probably not the style you want as they are about 14 in. wide (I personally didn't think that having a seat that is the widest part of the bike is stylish) but thanks for your interest.
Ok most people seem to like the cafe and modified stock styled bikes, so I am nervous to show my true hardtailed bobber as some folks may cry at the amount of frame massacre I have accomplished.
The first picture is how it looked when I got it. It sort of ran for about 15 minutes before i tore it apart.
Second is the progress thus far. Let me know what you think, sorry if I have offended anyone's idea of the way this bike should be treated.
