GSX1100G making squealing noise after clutch repair

[GS1000G Shopper]

I pulled the valve cover this morning and took photos of the #1 intake cam, #1 exhaust, #4 intake, and #4 exhaust. #1 intake looks dry, this was the area the noise seemed to be coming from.

EDIT
Deleted wrong information re: hoses from crankcase to valve cover.


Here are the camshaft pics:

I think my next diagnostic stage will be to pull the plugs and cams and then turn the engine over with an air wrench to check for oil flow from the hoses.

You're going to need some sort of method to support the cam chain if you plan on pulling the cams.

Why don't you get and read the factory service manual. Then understand it. In there, it will tell you that the oil hoses that you modified do NOT feed the cams but are for the oil flowing to the head to cool it. The oil to lubricate the cams and rockers comes up along the outside studs. And below those, are the restrictors. These, and others will need cleaning. So realistically, you should be splitting the cases to get to and clean out EVERYTHING! No half measures. Then, think about which head you will get to replace all the messed up parts.
Nuff Said.

I've completed that diagnostic and have oil flowing from both hoses in approximately equal amounts. It looks like the #1 cylinder intake side parts are fried- cam lobes/rocker arms. I can see galling & some discoloration while the others are bright & shiny.

I'll have to study the oil flow chart in the manual, but it seems like if something was jammed in one of the restrictors (there are one on each side of the block according to the parts diagram) it would affect all lobes on this side.

EDIT
Thanks Rusty, I figured that out when I tried turning it with a wrench. I used a piece of aluminum tubing to support the cam chain & tested it by turning the engine by hand. It worked well and I used the starter to spin the engine.

While I appreciate advice, I sure as hell do not appreciate attitude. Not everyone is an expert on everything. If we were, we'd have no need for forums like this one other than to showcase our expertise. Not everyone has unlimited funds to do things, and not everyone gets it right the first time. It's really easy to come down on people that don't know how to do what you know how to do. It's also the last thing someone that needs help really needs to hear.

I do have a shop manual my all-knowing friend. Here is the oil flow with the parts past the jets highlighted.



According to the manual, there are two jets (restrictors). At first after reading it, it looked like one feeds the intake side and the other the exhaust side. That being the case, it would appear the entire intake side should be lunched, not just the #1 & 2 parts. After looking at the rocker arms, it looks like the #1 & #2 side were galled. They were worse on the intake side. #3 & #4 looked much better. I then realized that each jet feeds the intake and exhaust for each side. That then is indeed the probable cause for the failure, as it is the choke point for oil. I AM AGREEING WITH THE PRIOR CONCLUSION IF THIS IS NOT CLEAR.

Maybe it's me, looking at your diagram, but does it look like to you the camshafts have an oil passage drilled inside them? If that's the case then that may be the reason for wiping out only one side of the camshaft.

I take it as the oil flowing out of the cam journal lubes the chain. The camshafts are hollow but are not drilled for oil flow where they sit in the journal.

The journal(s) should be oiled through a passage drilled in the head. Do the cam lobes have holes drilled in them?

Diagram... R. & L. oil jets> Stud bolts (XX side)> Cylinder head> (XX) rocker arm shafts> (XX) rocker arms> splash (drip) lube (XX) cam face's> Splash (drip) lube return.

Cam chain lubrication is a different path off the (XX) camshaft journals.

[rustybronco]

Oh and I mis-read the oiling diagram. it is the (XX) rocker arm shafts that should be drilled.

One other thing I noticed is that the main gallery that feeds the jets/restrictors is fed post-filter. I only run Wix filters on my bikes, so this must have been an accumulation of crud. I had flushed the bike with clean oil & a new filter since it had sat so long & then changed the filter again.

I pulled the head yesterday & the cylinder today. The heat here is so bad I can only work for a while in the shop each day. I'm going to look into splitting the upper case tomorrow so I can get to the other oiling jets.

After pulling the cylinder, I removed the head oil jets. Nothing obvious for blockage, but there was a spec of fine grit in one. The groove in the cylinder to the stud was clear. These are $7.73 new, so I'm buying all new ones plus o-rings.

I was pleased to see the base gasket was steel, so cleanup won't be as bad as the fiber GS gasket.
