Soliciting opinions CB550
« on: July 22, 2010, 11:54:13 AM »
Hey all,
   I was ready to go check out a 1978 cb550k - BUT, the bike was sold and the guy just hadn't pulled the ad from C-list.  Bitter.  Then I started doing some reading on various years of the 550 and began debating what year might be best.  Earlier cb550 carbs are easier?/cheaper? to repair it seems.  Power is rated at 50hp on all '74-'78.  There was a head cover Service Bulletin for the pre-'76 bikes (not sure if it was too big a deal as I haven't heard of any actual problems from riders besides the bulletin).  Plan is to ride for the rest of the summer and work on it this winter.

Long story short, there's another 1978 cb550k that is close that I'm interested in checking out.  Back to square1, it seems.  So...

A) Any particular model better than others or any of them to avoid?

B) Is $900 reasonable for the following year condition, etc., assuming it checks out?  (Seems reasonable to me, but then again, I know very little.)  Ad text is below and hopefully the pic shows up.

Any advice or help would be much appreciated.  As it's my first bike in 8 years (gave up my Honda Shadow when I had my firstborn), with little spare cash to invest in a bad decision, I'd like to do my best to avoid foreseeable issues and hope for the best w/the unforeseeable ones.

Cheers,
Greg

Looks to be a worthwhile buy.
That's what I'd like to hear.

That's exactly the sort of thing I wanted to hear (forks, not ugly) - now I know to ask when I talk to the guy!  Thanks...

BTW - I'll be back in Jersey in a couple weeks for a visit (that's where I had my Shadow) - did my grad school out there, then moved back to MN, sans bike.  Lived by Trenton, so went to/by Conshohocken all the time.

Did anyone get that? I understood the numbers:) Something about a two-Step heeels? Sounds like sweedish hip-hop.


Gman, come on, that seat is TERRRRIBLE!!!!! Replace asap. Something looks fishy with those forks for sure......however, that was the look back then. I have a 79 sportster, and it came from the factory with longer forks. In my opinnion, the bike looks retarded when the backbone is pointing to the heavens.

fletcha,

It's a given that the seat is fugly.  However, I'm less interested in the cosmetic that can be swapped out w/minimal cost and 20 minutes of my time compared to getting a bike that has a lovely seat, but is going to be a headache w/engine, etc., which = $$ and time.

With that said, the first thing I would do is ditch the seat. Or get some fringed leather for my wife and park her on the queen seat.

PS - how do you tell if the forks are original?

looks a bit messed with/choperized. front sits too high, rear 16" is not stock, dont want to think about how it handles. the seat is another story...

unless you like that kind of look, dont touch it.

The chopper craze of the 60's and 70's probably ruined as many bike as the cafe/bobber craze does today.

The front forks are extended, probably 4-5 inches.  The rear wheel looks to be a 16 inch instead of the stock 18 inch so it cound have a big sidewall tire like the rigid frame choppers often had to diminish spine disc compression.

Choppers were mostly open road machines as turning away from a straight line meant a concerted effort.  It also meant you didn't have to focus on on going straight.   Turning them quickly was not expected to ever happen.  It short, "chopperizing" ruined all the excellent handling traits the CB550 was well noted to have.

The good news, is that you can change it back, probably with used fork tubes, and a used rear wheel.  Someone who wants a bobber will likely buy your rear wheel/tire.

The exhaust bears close scrutiny, as they tend to rust out, and stock replacements are not very easy to find if you aren't very lucky.
While changing the exhaust is not hard, the carbs on this model are finely tuned to the exhaust and stock induction.  Changing either is going to mean a carb re-jet, and you can most likely kiss your 55MPG goodbye in the process.  So, look carefully at the mufflers for rust-though where water can collect at the bottom.

It's a sweet bike in stock form.  But, I don't demand that a bike look like a cafe racer to be a good bike.

Gman, parts for the 74-76 cb550s are more ubiquitous and interchangeable between those years. i have a 77 cb550 which i love but if i could do it all over i would look for an earlier year.

Thanks... all very helpful information to help with the decision.  I think I'll keep my eyes open for something less altered.  Appreciate it!

I'd go look at it, see how it runs and ride it if possible. If the motor & frame aren't molested, maybe you can talk him down on the price? Parts are plentiful for these bikes and can be reasonably priced, I would not rule this one out yet unless you do not want a project.

Personally I like the looks of the earlier 550's. Some things I like that don't come on the 77-78

Exhaust pipes are way cooler, fork gators instead of dust wipers, color schemes and emblems/decals, position of turn signals next to the headlight instead of below it. Little things I know but all together make a cooler more retro classic look.

Like the 77-78 CB550's the best as they have improved handling mostly due to longer inner fork leg. Action is more compliant, feel is better. Have the improved rocker shaft locators as well so sort of a better engineered/sorted 550 as honda came to end the model run. These little bikes are tons of fun, handle well and can be made to go and stop pretty easy using modern technology in suspension and braking. Get a good low mileage bike that been cared for and you'll have a great base to build on.

Keep the input coming!!  So, next question - K or F ??  From what I gather, the K will be easier to deal with for parts, etc.  Any performance difference to speak of?  And, what's a reasonable price?  I'm thinking around $1k for a decent project bike (running, not too mangled).  I appreciate you sharing your experience w/me.

Cheers,

What are your project goals?

TT -

First and foremost, to have a ride!  Once that is accomplished, the rest is icing on the cake.   :)  In an ideal world, I would ride the rest of the summer and tinker over the winter as the weather turns unfriendly and cash becomes available. 

1 - For the bike, I guess I would try to get it sorted out w/updates/upgrades (tapered bearings, carbs cleaned and synced, swingarm bushings, etc.) to make it as safe and tight a ride as possible. 

2 - Then, as parts and time became available (and aforementioned money), I would swap tank for something like CX tank w/knee scoops or get some fab work done, redo the seat pan w/a rear cowl, get some rearsets, clip-ons, etc. 

3 - Once the bike was looking the way want, strip it all the way down, de-tab the frame, powdercoat, polish, paint, etc. and put it back together.

I think I've heard other people call it a 2 stage restoration.

To that end, the better shape the initial bike is in with regards to running condition and how shiny the bits and pieces are, I imagine the less time/effort I'll have w/tinkering later.  However, I have more time than money, so cheaper w/elbow grease is better than spendy.

Sound reasonable or do you have any ideas, see any pitfalls?  I'm glad for any input!  Especially if it means finding the right model that won't require heavy mods to bring it up to snuff or is notoriously hard to find parts for or work on.  For instance, I know the earlier 550k's had head covers that may be problematic (via the Honda Svc Bulletins), but I haven't heard whether that is a widespread problem in real-life.
