Cylinder Head Bolts?

I removed the camshaft cover (2 bolts)

I removed the sprocket (2 bolts)

I removed 7 of the 8 cylinder head bolts (broke one off at the threads)

I easily removed the values, rockers, and head. I tried to remove the cylinder, but i am beginning to think that the cylinders are partially threaded into the bolt I broke off. I was assuming the threads were solely in the crankcase, but I am beginning to think the threads come up into the cylinder and that is why I can't jar it loose. Thoughts?

Update:

Thanks Motoman. I just got it cracked loose, and i do have a manual, but am trying to learn thats why I am making some mistakes here. just a project i am having fun with. any suggestions on how to get out the broken off cylinder head bolt? I have about three inches of shaft left to work with...

    OK so one of the 8 is still in the engine case, no it is not threaded into the cylinder and the case, only the case. For reasons that will take to long to explain, it can not be threaded into the cylinder.

    However there are usually separate bolts that hold the cylinder to the engine case. btw, you need a shop manual.

    For future reference, always give year, make, engine size and model # when asking questions. We need all of that info to give an informed answer.

    Without knowing what bike you have, I cannot give you a definitive answer to any of your questions.

    As MotoMan said, the bolts probably have nothing to do with holding the cylinder on.

    Most common problem is the base gasket is sticking to the cylinder and crankcase.

    Do not hammer a screw driver in between the cylinder and crankcase to pry them apart (it will damage the mating surfaces and create a leak).

    Look for a solid protrusion that you can hit with a hammer and block of wood.

    I've hit cylinders sideways with a "dead blow" hammer (plastic hammer with shot inside).

    The shock breaks the gasket's hold, making it easier to tap the cylinder up.

    If you don't have a dead blow hammer, place a block of wood against the cylinder and use a regular hammer.

    Don't hit the cylinder very hard, you don't want to break it.

    And be careful of the area of the cylinder you're hitting for the same reason.

    You want the area solid - no water jackets or cooling fins.

    For destiny reference, constantly provide year, make, engine length and variety # while asking questions. we choose all of that information to offer an stated answer. without understanding what bike you have, i won't be able to offer you a definitive answer to any of your questions. As MotoMan pronounced, the bolts probable have no longer something to do with keeping the cylinder on. maximum undemanding concern is the backside gasket is sticking to the cylinder and crankcase. do no longer hammer a screw motive force in between the cylinder and crankcase to pry them aside (it is going to wreck the mating surfaces and create a leak). seek for a sturdy protrusion which you would be able to hit with a hammer and block of timber. i've got hit cylinders sideways with a "lifeless blow" hammer (plastic hammer with shot interior). The ask your self breaks the gasket's carry, making it greater straightforward to faucet the cylinder up. in case you haven't any longer have been given a lifeless blow hammer, place a block of timber against the cylinder and use a time-honored hammer. do no longer hit the cylinder very stressful, you do no longer choose to break it. And be careful of the portion of the cylinder you're hitting for an identical reason. you decide on the section sturdy - no water jackets or cooling fins.

    a head gasket does an amazing job of sticking the jug to the case, you may have to just pry up to break the gasket's seal.... just don't pry against any ribs, you don't wanna bust a fin off

    then you can hopefully have some bolt left to get a stud extractor or vise grips onto, easy outs suck on head bolts, you bust off an easy out and all you can do is a heli-coil which isn't a good option for head bolts
