    In this thread. Please be kind. I have made yet ANOTHER colossal and stupid mistake while trying to take the engine cover off. I was thinking righty loosey lefty tighty and ultimately broke these clamp type things (See photo). What do I do. How do I get new ones! Please help.

    Someone on here can probably find them, or has them.
    I would message xjforever, the engine icon top right, Len a.k.a. Chacal may have them or can probably point you in the right direction. :)

    The good news is you broke the ones that are not cam caps, so all you need is two new replacement ones. We all make mistakes, no shame in that.

    Oh no, I broke all four of them. I'm just showing you one side. All four of them are toast.

    When you get new ones the torque specifications assuming you have enough clearance to get the torque wrench in below the frame are 10Nm for the cam cover bolts and 10Nm for the camshaft cap nuts so l believe the sheared bosses for fixing the cam cover next to the cam tunnel are the same.

    Two of them are actual cam caps. For the most part they an interchange, but you should get some plastiguage to make sure the clearances are still within specification. The cams run in plain bearings that are line-bored with the caps in place on the bare head. The only issue will be if the replacements are worn beyond being useable. You will also want to measure the cam endplay, since the inner cam caps also keep the cams from moving to far to the left or right.

    If someone on here does not have a set to sell you can get tnem on Ebay, but might need to buy a used head to do so.

    Standard or yics head? I think the only ones I have are for 650/700/750 engines. Don’t know if they are interchangeable. Caps in pic look like yics caps but head looks like standard head ? Maybe caps have been replaced before. And they look like they are the wrong way around.

    No disrespect to your uncle but better to replace them with second hand parts I think.

    If the FZ600 fits, I assume they will, you can have them, postage is all it will cost.
    You do the research. If they’ll work I’ll dig them out.

    I appreciate every one's response but I think I just pretty much killed my engine. I proceeded to do the valve job (6 of which were out of spec) I used the zip tie method to hold down the lifter so as to fish out the shim. Yup, you guessed it. The end of the zip tie snapped and is now lodged inside. The crankshaft can only turn so far and then it gets completely stuck. If I owned a gun....
    I humbly ask all of you what are my options at this point.

    Try using air through spark plug hole and see if it will shoot out through the intake or exhaust.

    Yes Toomanybikes worth a try. If he has a borescope he can possibly see it if it is on the piston crown. A piece of rubber hose attached to a vaccum cleaner could be used to get it out if it is on top of the piston. If he had a cork that would go into a vaccum cleaner hose with a hole in the cork to take a small rubber pipe which could go through the spark plug hole. Might work, just brainstorming.
