few questions for you 550 owners (or all owners also)
« on: February 16, 2009, 03:25:55 PM »
I have a 1974 cb550k. So i road the bike for about 10 miles today and have a few questions that anyone might be able to answer.......

1. How stiff are the shocks supposed to be on these things. I was riding down a country road and when i hit bumps it felt like there was hardly any absorption in the front forks and im not sure about the back shocks. How rough is it supposed to be riding these bikes?

2. When i do hit bumps my center stand bounces a little, at first i thought it was my engine or forks making noise but i realized after a few that it was the center stand, does this mean i need a new spring to put on it to keep it tighter?

3. When not moving it is tricky to get it into neutral, it goes through the gears just fine but its sometimes doesnt want to go into neutral but just pass it. Is this normal?

4. How much smoke is supposed to come out of the blow by tube? my smokes a lot. it didnt do that until i put some Seafoam in it. Is this the Seafoam burning off some crud in the carbs and stuff?

5. I got some popping after a little while to but only for a few secs, is that the engine burning off something?

1.  It's hard to quantify something like that over a message board.  The shocks and forks should do a relatively good job of absorbing the bumps, but they're not going to be anywhere near modern bike standards.  If the rear shocks are stock, then they're most likely shot.  Do they move up and down smoothly when putting weight on the bike?  Same with the forks? 

2.  The center stand should stay snug in its resting position when riding when going over all but the biggest bumps/potholes.  If it doesn't, then you may need a new spring.

3.  It may be somewhat "normal", but it's not the way it's supposed to be.  Your clutch may just need to be adjusted.

4.  Are you talking about the valve cover breather hose?  You shouldn't see much smoke at all after it's had time to evaporate any water that's collected in the crankcase.  Unless you put the seafoam in the oil instead of the gas, it shouldn't cause excess smoke from this breather.  Smoke from this breather can be an indication of bad valve guide seals or piston rings.

1. When i am riding the bike i can bouce up and down and they give a good bit but i am not sure about just sitting my weight on the bike.

3. I adjusted the clutch today. At the adjustment screw i loosened the nut then turned the screw all the way out and then back in 1/4 a turn, is that correct? Like i said it shifts through all gears fine its just hard to stop half way between 1 and 2nd.

4. i dont know what the name is but it comes of the cylinder and its on the right side of the engine at the very top by the carbs.

The stock rear shocks are pretty soft, and they lose their damping action fairly quickly.
How much weight are you putting on it, and where have you set the pre-load adjusters?
The front forks/shocks are also pretty soft with the usual fork oil viscosity.  Too much oil (or too high a viscosity) can make them pretty stiff, though.
They should be firm enough that a panic stop does not bottom out the fork travel.  But, the front will dive quite a bit.

2. When i do hit bumps my center stand bounces a little, at first i thought it was my engine or forks making noise but i realized after a few that it was the center stand, does this mean i need a new spring to put on it to keep it tighter?
The center stand rests on a rubber bumper fitted to the muffler.  I never noticed it bouncing on it.  Maybe it does, and the bumper absorbs the noise/sound.

3. When not moving it is tricky to get it into neutral, it goes through the gears just fine but its sometimes doesnt want to go into neutral but just pass it. Is this normal?
That's a dragging clutch.  Warped plates, wrong or old oil, or mis-adjustment of the clutch bits.

4. How much smoke is supposed to come out of the blow by tube? my smokes a lot. it didnt do that until i put some Seafoam in it. Is this the Seafoam burning off some crud in the carbs and stuff?
There is a difference between smoke and water vapor.  Water vapor should continue until all the water is vaporized from the engine/trans unit.  This usually takes about 15-20 minutes after teh engine is a full operating temperature.
If the smoke is actually gases blowing by the rings, you have my condolences.

5. I got some popping after a little while to but only for a few secs, is that the engine burning off something?
Dunno. Are you feeding it popcorn?

If not check your timing, valve clearances, exhaust pipe seals, and air/fuel mixtures.  Take two asprin and call me in the morning.  Did you do your co-pay?

1.  Without riding your bike, I can't say if the suspension is working as it should or not beyond the extremes of giving no support at all or being completely stiff.  You'll have to decide for yourself if it's good for you, and if not take steps to make it better.

3.  A lot of times fresh oil will help smooth out the shifting.  Has it been a while since the last oil change?

4.  The valve cover breather is at the top and center of the engine.  Is this what you're talking about?  There shouldn't be any breather hose coming out of the top right side of the engine.

man this sounds like a lot more trouble than i was expecting.
1. i only weight 155 so i am not putting much weight on it. and as for pre load adjusters i have no idea what that is haha. i am still a newbie. Actually just found a guy who lives close and has a 750 who said he would help me learn things.

2. i will check for the rubber piece. where should it be located?

3. Even if it shifts through all gears fine is still is bad? I saw were you suggested castrol oil two tired, but what type? the clutch didnt do it i dont think until i adjusted it today. Did i adjust it wrong?

4. Smoke/Water vaper is like a light grey color it hazes up the garage but its almost so light its not present. What do you mean by if the smoke is actually gases blowing by the rings? i am assuming that is super bad since you say you have my condolenses?

5. I dont get the co-pay joke haha

4. http://www.bikebandit.com/assets/schematics/Honda/HJ0906W0130007.gif
number 21 is the hose i am talking about

3. i changed the oil back in say september but wasnt able to get the oil filter off bc of the stripped nut, but i havent really ridden it because it has been being worked on paint wise.

Trust me.  When it's all said and done, none of us do! :D 

We do it because we enjoy it (you have to be a bit of a masochist), not because it's cost-effective. ;)

so i have been searching and what TwoTired is talking about seems like bad piston rings, am i correct by this?

Any advice on adjusting the clutch so i make sure it is right?

You need to do a compression test on the cylinders to asses their condition.

Was the bike sitting for a long time before you rode it and noticed the smoke?  These bikes don't like to be neglected and will act inappropriately for a while once they're started up again. 

As for the clutch, just follow the procedure in your manual.

well i bought the bike in september and havent been able to ride it do to needing painting and the COLD. so yeah i guess it has been sitting a while. i dont know how much it was ridden before then. I dont have access to a compression test at the present time. I just got in touch with a local owner here who might be able to help me, if not off to the mechanic.

I followed the procedures in the manual and i just dont know if i did it right. Like i said it shifts fine through all gears its just tricky and i skip neutral easy sometimes. Maybe its just my horrible touch.

If you've got a friend with the tools, then definitely make use of them.  Don't take it to a shop unless money is no object.  You'll never be happy with your bike if you're continually paying somebody else to "fix" it, and then taking it back again and again for the same problems.  These bikes are for folks who do their own work. 

Do the clutch adjustment procedure again.  If it's still hard to get into neutral, that may just be the way it is.  Your clutch may be near the end of its adjustability, or the gears may be worn.  These are all things to be expected with a bike this age.  Certain things you can deal with or work around, and once you can't do that anymore, you fix it.

My 550 has always been kind of a pain to get into neutral once the engine's hot, but I work around it.  Try shifting into neutral while the bike is still rolling forward a little instead of waiting until you're completely stopped.

yes mine is much easier when rolling, i say its hard to get into neutral but i am kind of referring to when its stopped. PS i miss living in denver, miss snowboarding so much.
As far as the friends with tools i will see what all he has, he just contacted me today so we will see how that goes. Hopefully i will get look and he will help me out a LOT haha

I tried three or four kinds of oil until I found one that worked good with my clutch. I ended up using Pennzoil 10w-30. Whichever one you use find one withOUT a friction reducer. It can cause the clutch to slip. Also check to see how much oil you put in there, I put too much in one time and had very similar problems, clutch was acting up, hard to find neutral at a stop, and smoke from the breather tube.

and if you have fun riding and wrenching on it, it's worth every penny! ;)

you know i prolly did put to much oil in it because i read somewhere to check the oil while it was on the kickstand but then read the manual for the bike and it said while it is on level ground and upright so there is prolly way to much in it. I will change the oil soon and go with castrol and see how that works. I have some valvolien in it now i believe

man this sounds like a lot more trouble than i was expecting.
1. i only weight 155 so i am not putting much weight on it. and as for pre load adjusters i have no idea what that is haha.
The stock shock has a preload device on the rear springs.  With the right wrench, called a pin spanner, you can turn a stepped collar on the each shock to pre-compress the rear springs.  It's mostly there to compensate for extra loads like an added passenger.  At 155, you probably don't need any added pre-load.  I know lots of guys that crank them up to max as routine.  Maybe your P.O. did.

2. i will check for the rubber piece. where should it be located?
The bumper is on the left lower muffler.  When I had a 4 into exhaust on my 74, I had to make a stop bracket for the center stand. and the bumber was mover on to that.  From memory, it's about an inch square. and a half inch think soft rubber.

3. Even if it shifts through all gears fine is still is bad? I saw were you suggested castrol oil two tired, but what type? the clutch didnt do it i dont think until i adjusted it today. Did i adjust it wrong?
It's possible you adjusted it wrong.  It's not really bad, it's just irritating.  I have a bike that does this.  Readjustment helped, new oil helped, but, it still does it when hot.  I bought a new clutch for it.  But, if I don't make it slip a lot, or do drag style take-offs it's not so bad I a feel the need to actually replace it. Rocking the bike fore and aft while doing the neutrals search almost always allows neutral selection.  I can always select neutral easily if a remember to do it before the bike has completely stopped.   Also, Honda's HP-4 10-40W without Moly seems to have really minimized the problem, (which does get worse with higher engine heat).
While I have used Castrol in the past (15 years ago), I don't think you got that recommendation from me.  I rather like the semi-synthetics, like Honda's HP-4.  Not saying Castrol is bad.  I just think others are better for this application.
As for adjustment, sometimes it works better after the second try at adjustment.  Adjust at the clutch cover first, then adjust the cable.

4. Smoke/Water vaper is like a light grey color it hazes up the garage but its almost so light its not present. What do you mean by if the smoke is actually gases blowing by the rings? i am assuming that is super bad since you say you have my condolenses?
The #21 hose is the engine breather.  It's supposed to go to the breather filter that's inside the filter box.  Those vapors are sucked into the carbs, normally.
Water forms on the inside walls of the engine each time the outside temp is cooler than the inside temp.  It does this at a faster rate when the humidity is high.  This water vaporizes when the engine get warm and exits the breather.  If the engine gets hot for a long enough period of time, all the water is vaporized and the "smoke" stops.
How long have you run the engine after it was fully warmed up?  Cold weather extends the warm up period, delaying full vaporization of the engine water condensate.
If it still smokes well beyond the time when all the water is vaporized, then piston ring blow-by might be a cause.  A properly conducted compression test or leak-down test would usually tell you if rings are working as they should.

5. I dont get the co-pay joke haha

You don't have an HMO, or go to the doctor often then, I suppose.  I have a $15 co-pay each time I have a doctor office visit, that insurance doesn't pay for.
The two asprin is an old doctor joke.
The copay is a modern addendum to a doctor joke.

Are "explained" jokes ever funny?

1. i do not have this tool so i cant do that adjustment at this time. i will check into that later as this is low in the priority list.

3. I looked back in the post and it was Hondaman who wrote about castrol, sorry about that confusion. Where do you purchase the Honda HP-4 10-40w.

4. Could the smoke be from to much oil in it? Someone said they had the same symptoms and that was what was at fault on theres?

5. And yeah jokes are still funny sometimes when explained. I wasnt thinking a medical copay, and as for the 2 asprin, i got my undergraduate degree in athletic training and we love to joke at how if you go to a general practitioner with a sports injury they tell you "give it two weeks rest" for EVERYTHING hahaha

OK

2. Hey what happened to 2?

3. I looked back in the post and it was Hondaman who wrote about castrol, sorry about that confusion. Where do you purchase the Honda HP-4 10-40w.
This one made me laugh.  'Cause, I get Honda oil from the Honda dealer. ;D

4. Could the smoke be from to much oil in it? Someone said they had the same symptoms and that was what was at fault on theres?
I suppose if the oil level got high enough to contact the spinning crank, it might vaporize it.  I wonder how much oil it take to do that.  I've done half quart overfills, accidentally, and it didn't smoke.  Then again, my breather tube is hooked up to may air box, so I might not have noticed.  :-\

I like it.  Two weeks rest sounds pretty good.  Who the heck is going to argue with that?  The sports team owner?   ;D ;D

what happened to 2 is I am laying in bed and not going to get up to check for the rubber tonight

3. I should have clarified "besides the honda dealer", my own ignorance there

4. I guess i really should get the breather system set back up to stock huh

5. and the answer to that would be the owner, the coach, the media, and every crazed fan of that particular team haha
