camchain and mystery part?

I have a barn find 79 b3 kz1000 project. 45kmiles.
Pretty beat up. Top of the engine is pre79 bottom is 79.
Basically they removed the emissions stuff.
I am rebuilding the motor at this time here is the questions?
First when I removed the head and than pulled up the second part and put a long flexable tool with a magnet on the end through to hold up the cam chain. After getting the engine components off I went to pull out the magenet after tieing up the cam chain of coarse there was a part on the magnet I dont know where it came from.
I have the repair manual and I can't find the part in there. I watched several youtube videos and its not in there.
I am including pictures of the part.
In the pictures youll see the orange handle magnet tool I ran between the engine.
One other q uestion I have is about the cam chain. If im holding the chain up tight should it slip when I turn the engine over by 17mm bolt under timing cover?




Than you

first pic is a cam chain guide.....73-80 engines.

Wow. That engine is pretty whoopped up! Those are higher compression aftermarket pistons.
That part is the cam chain guide that sits in the cylinder block to the front of engine. Directly across from ther chain adjuster boss. It is held in place with a 6mm thread phillips head screw.
Who ever built that engine did not put any lock tight agent on that screw. Thats why alot of guys strip that phillips screw trying to take it out.
So there is also a screw in the bottom. Unless that bracket broke? Is the little 6mm hole intact or lock cracked, broke in half? Opposite side of your picture?

Take that engine out and dismantle it!

OK, I did not see your first pics. Yes that part broke off!

Thanks for your response. I was trying to decide if i was going to dismantle the rest of the engine.
I guess I have my awnser.
How do you know those are aftermarket pistons and not stock? How do I know what rings to get for it if its not stock?
Thanks again for your help!

extended dome on top of piston...the dome is used to raise compression.

stock pistons dont have dome. (see pic below)

I Have the one for the z900 in the file base here. and I have a Old Old Klymer. This Motor is so custom its tough I dont know which one to get. I fear Ill buy one and it will be the wrong one and I ll just have to buy another. For instance the part in the link you provided earlier that obviously is in my 79 bike is from a 78 a model according to that sight.
Any sugestions? There are a couple on ebay. Just dont know which one.

Sorry about poor pic quality. Goes in front of cylinder head....can only go one way, only one screw hole.

Thanks again.
Nice bike BTW. I checked out your bike pics and that is one sweet ride.

Thanks, If we can help let us know.....
