another technical question

MSGQ
Spoke with a CB750 smart guy today.  Seemed to know his stuff but I'll throw this out for the group.
I was explaining what I thought was cam chain noise and among many other things he suggested that I take of the front and rear inspection covers on the number 1 then the number 4 cylinders. Start the bike and the result should be a messy spattering of oil.  Well, I tried it and only the front of the number 1 cylinder actually sputtered oil, all others appeared to have a coating of fresh oil on the valves but did spew the oil.  What do you guys think?

As long as there was fresh oil, your OK. It's probably your carbs out of sync.

Thanks again, it seems all roads lead to Carb Sync.  I'll update after it's done.

Thanks for reenforcing the carb sync issue.  Had them done today and what a huge difference.  It's like riding a different bike when I'm running at lower rpms, and the feared cam chain noise is gone.  No more tinkering for a while, it's time to get my knees in the breeze.

Those are NOT inspection covers.
They are Tappet valve adjustment access covers.
Of coarse there will be oil in there. So what. Means nothing as far as your cam chain.

IT has nothing to do with the cam chain.
The cam chain must have the slack taken out of it before the valves are adjusted.
The number #! cylinder must be 15º BTDC (see the special mark on the crank) Alternator flywheel.on the compression stroke when the cam chain
adjustment is performed. GET A SHOP MANUAL.

Then adjust the valves.
Remember a little ticking noise from the tappets is not necessarily bad.
But a tight valve that makes no noise will burn a valve because it is only when the
valve closes and touches the valve seat that it can transfer the heat into the cylinder head and then to the atmosphere.

Whew, feels like I just got a "talkin-to" thanks Dad!  Try the other side of the bed next time you get up.

Thanks to this site and SOHC I've been able to find all the manual support I've needed so far.  For what it's worth I did attempt the cam chain business prior to the Carb Sync as it was something I could do myself with the tools I own.  

Like I say - she's running like a top now!  I'm out - I have enough aggravation in my life that I should deal with knuckleheads on a forum I thought I might like.

Thanks Again it was short but sweet!

I have re-read his post several times now. He was a little strong, and I can see how some would take offense. It must be realized that on these forums, you can not hear voice tones, or see facial expressions. Face to face the comments probably would not have meant a thing, but on a forum it's a different matter. Especially when you are new, and do not know anything about motorcycles, or mechanics. However like, you stated Donald does give some very good advice.

The art of diplomacy is saying "Nice Doggy" until you find a stick to throw.

http://en.wikipedia.org/wiki/Netiquette

Even the best advice is subject to the way it's delivered.  We all have a great deal to learn, and in turn, have an opportunity to teach others as well.  I tend to educate others as I would like to be educated.  Your mileage may vary, and your approach may vary as well.  Know your audience, and adjust, or your contribution may not be that well received, and flaming wars might ensue.

This forum has been a civil and helpful place as long as I've been showing up (almost 1.5 years now). Let's keep it that way, OK?

Discussion via messaging might be better than airing laundry in public.

About my "attitude".

When I post a reply to any forum members I am NOT being condescending in any way.
I just give the information. If I add Capital letters it is only to emphasize. Thats it.

When I say, "GET A SHOP MANUAL" in capital letters it is because I feel it is
very important to working on any machine and it is NOT to punish you .

I want people to have the workshop manual to prevent damage, lost time, more posts on
this forum on how to fix broken aluminum castings and other expensive disasters.
So i capitalize some things to tell you that I feel it is VERY important.

I am NOT mad at you. I just really want you to get a shop manual BEFORE working on your engines.
You cannot rebuild any engine just by asking question on the internet. It is TOO LATE to prevent
the damage by letting you make your own discoveries(disasters$$$).

I cannot control what others do.
But I can capitalize certain words and let you know how important something is.
If I say, "get a shop manual" in capital letters it is because you are asking questions about information
that is in the shop manual that you would need to know BEFORE taking something apart.
So I know you are working without a book.

I also do not care if you are the president of a country, A former whatever.
I just tell you information that I know is true and correct and I am very careful not to
say anything that is incorrect. I always double check my information in a BOOK before I post the information to make sure you do not make a mistake  from incorrect information.

And  can attest to how much damage can come from bad information!  I'm not going to get into specifics but on a different forum I got bad advice and the thought of it still gets my blood pressure up.  I can also attest to the importance of a good (preferably OEM) shop manual.
In 1972 I had to make a choice...quit riding...or quit drinking.  God says it's safe to get back in the saddle now...at least I'm still alive...and feel more alive with the wind in my face!  Now riding "Helen Black"...1982  CB750SC.
