Whineing to no end!

update

I put the valve covers and coils back on. Plugged the vacume line and plugged a funnel into the fuel line. My intent was to insure that Suzi Q would start when I bumped it. I filled the funnel with gas until it stopped bubling and hit the starter, boom fired right up. Yes the whine is still there. I grabed the stestacope and started searching again, screwdriver, metal rod and finally a doctors stestacope and searched some more.

What I found is the whine is loudest behind the clutch cover. Looks like a new gasket and inspection.

Any thoughts?

Its a stange sound for a clutch to be making.

I would have to say this one has me stumped.

Have to remove those rh covers and inspect...
Clutch basket bearings.? my guess

Well I need to have a new rear tire put on Suzie Q, so have been making more room to work in my single car garage. Since I will be pulling the exhaust I might as well pull the engine and take a look at the whole thing. The whine is definitely coming form the lower end, loudest behind the clutch cover but can be heard behind the timeing cover and stator as well.
I wonder if it was ridden with gas in the oil and messed up the bearings. Time will tell.

Hey Cheif!

Hey Cheif!

Well the jugs are off and the guides are out.

The long straight one (the front) is not overly worn compared to the new one the road gods took as taxes.
The rear shows that the tenshioner was definitely working, and in my opinion the rear guide is shot.
The next chance I get work on the old girl, I will measure the timeing chain for wear. Say Chief, do you have the minimum length between pins so I can compare for stretch.

I don't know. I'll do some research. I can't fine that info in my Clymers.

Neither could I, Say where is the best place to get a complete gasket set. Would really like the layered head gasket.

I bought mine from APE but my head gasket isn't stock anymore.

Suzuki service data manual states 157.80mm (6.213in) between 20 pins as a service limit.

Suzuki mad

 

[gustovh]

Would that be center to center on the pins? inside or outside of the rollers?

You can usually find gasket sets at Bike Bandit (slow) or z1enterprises (quick, and you can talk to a knowledgeable person).

 

[Suzuki mad]

It doesn't say but I would guess that its the same span as for the timing.

Suzuki mad.

Well ordered the full engine gasket set, new chain and link today and will order the new guides this afternoon.
Cheif what is involved in replaceing a cylinder sleve? My # 1 cylinder has a few brown spots in it that I don't muchg care for.
Most wear in the cylinders is in the front and back. All cylinders still show original factory hone marks.
Carbon on top of pistons and cylinder heads, flakeing off on #s 1&4 piston tops, carbon that is.

The base gasket took 3.5 hrs. to remove.

A machine shop presses out the old one and presses in the new one.

 

[gustovh]

I thought that was the case. Just waiteing on parts now. Say Cheif, how about a picture of your 1100 L.

Gustovh have you found a reason for the noise yet? Earlier you were going to inspect the clutch area now posts would indicate that you have pulled most of the motor apart.

Your replacing parts but has anything given the indication of being worn out or in trouble to have caused that noise? You are talking about the chain slider with groves in and now this sleeve....would that have caused the noise.......is your desire to change it going to give you more problems as you go?

Would be such an anoyance to do all this work and then find that she's still whining after a rebuild.

Suzuki mad.

I have a full engine gasket set coming. The rear cam chain guide/adjuster is worn and floppy, so I will be replacing it and the front guide, and cam chain. I am not going to worry about the cylinder, I do not see how that could cause such a racket.
I restarted the engine before I pulled the jugs and used a automotive stethoscope, steel rod, screwdriver, and finally a doctors stethoscope to try and track the noise again. I have bad hearing but seemed to me I could hear it all over the lower end of the engine/transmission.
I just finished cleaning the jugs, head and valve cover and will take the head to work next week and check it for warping.
Will pull what is left of the motor, and inspect everything else. I need to move things around to have the room to work.

Not quite stock, there, Haaay Chief. Looks good and I bet rides goooood also.
I now have all the parts required to reassemble the engine, replace the Cam chain, front guide, chain tenshioner (rear guide).
Inspected clutch and bearing, Nada. Crank bearings, nada, Starter, cams, seats etc. Nothing reared it's head.
Will start assembly in the next day or two.
