Now jensen ya a big boy and at times we are associated with young folks who don't need the real/total reason why they feel wet when they shower/bathe.
Sort of like the thread on oil where if one didn't get with ya they were questioned as to why.
I do my best to get to the point/subject and seldom need to embellish my ideas/reasons.
KISS is what I mean. .........lm

Haha, KISS - I havent heard that thrown around since grade 5 math class, my teacher used to always tell me to Keep It Simple Stupid! Needless to say, I didnt listen... Still managed to complete 2 university degrees (one being in Pure Math) I guess some people like the challange of the complex path in life...

Thanks Sacha,

Now knowing what kiss means it does place things in perspective for sure,
thanks for revealing the real meaning of it, I thought is was meaning keep
it simple and small, or keep it short and simple, but I was wrong I see,
how stupid of me.

Ed, what does your version mean ?

btw Sacha I went the complex path too, having a degree in physics and mechanics.

Jensen, The engine is cleaned and inspected, ive been restoring my CB , it has been sitting for a few months now while working on the rest of the bike.

The engine is clean inside and I know I installed all the parts correctly.

The clutch, from what I already thought, now sticks because it's been 'sitting' all these months.

Just like Davomoto confirmed 'it's common'

That all I needed to know.

And I 'check' debris , mostly you will find parts of hard rubber and parts of smallish metal.
Trust me, I can tell what comes of a clutch and what not.

99/100 times you find clutch debris in there, I already stopped worrying about such debris.

When bearing parts are starting to come off, you know that instantly, by a failing engine or by lots of noise.
Finding bearing parts while checking the filter (as routine), is unlikely. Because chances are big that the engine already broke down before you checked it.

I learned to go by ear, maybe that where we differ. You can't teach noise or sounds out of a book, nomatter how much university degrees you got. ;)
Experience is all, we all got our own ways. One would would for you, but would not work for me, and vice versa :)

When my CB is finished I surely come to pay you a visit Jensen ! :)

Hi,
The clutch, from what I already thought, now sticks because it's been 'sitting' all these months.
I have never experienced this, the clutches from my '67 and my '62 (my riders) just don't seem to stick, don't know why. My CB450 clutch doesn't stick either. Maybe it has something to do with the thick oil people tend to use in these engines, and the surface of the clutch plates in combination with the thick oil ?

You couldn't be more wrong here, why do people tend to think, that a seat of the pants is the opposite of gaining knowledge and a broad interest into the deep reasons behind the obvious ? I didn't study because I didn't want my hands dirty, I studied because I wanted to know more and get my hands dirty. The only reason why I did physics because I wanted to know how the world around us works and why.

I say it regularly, take a stethoscope and listen to the engine. I read that you did a lot with mopeds, so did I, at the same age as you. I still have a SS50, CD50, PC50 and more.

Living the KISS way has it's boundary's, it means that you maybe know the solution but never ever have a clue why it works or not. And not having a clue, means no evolution in solutions.

The KISS way is an evolution of the wet monkey theory,

( Start with a cage containing five monkeys. Inside the cage, hang a banana on a string and place a set of stairs under it. Before long, a monkey will go to the stairs and start to climb towards the banana.

As soon as he touches the stairs, spray all the other monkeys with cold water. After a while another monkey makes the attempt with same result, all the other monkeys are sprayed with cold water. Pretty soon when another monkey tries to climb the stairs, the other monkeys will try to prevent it.

Now, put the cold water away. Remove one monkey from the cage and replace it with a new one. The new monkey sees the banana and wants to climb the stairs. To his surprise and horror, all of the other monkeys attack him. After another attempt and attack, he knows that if he tries to climb the stairs he will be assaulted.

Next, remove another of the original five monkeys and replace it with a new one. The newcomer goes to the stairs and is attacked. The previous newcomer takes part in the punishment with enthusiasm.

Likewise, replace a third original monkey with a new one, then a fourth, then the fifth. Every time the newest monkey takes to the stairs he is attacked. Most of the monkeys that are beating him have no idea why they were not permitted to climb the stairs or why they are participating in the beating of the newest monkey.

After replacing all of the original monkeys, none of the remaining monkeys have ever been sprayed with cold water. Nevertheless, no monkey ever again approaches the stairs to try for the banana. Why not?

Because as far as they know that is the way it has always been done around here.)

Same here

Ya assume again.
My plates don't stick either!.
Your statement below.
Thick oil!. ..................lm

Hi,

No, not yet, maybe after the winter ?, I'll see.
No assumptions, just experience on my two riders.

I look for reasons, that's why I use the magic word maybe, as I'm not sure.

To make this conversation going somewhere, does anybody know why the clutch sticks after a few months of sitting ? is it the friction material ? the construction of the clutch ?. oil ? other reasons ? a combination of the above ?

Both my riders have a lot of nos clutch parts in it, is it something that only seems to appear on used clutches ?

I don't want to be a monkey, saying it is there and this is the solution, but I don't know why it is happening, and I don't know why the solution is working.
