So, Col had this running before, how the feck, transporting it from his to mine have I messed them up

Bugger. Before you go ripping the engine to bits take the cam covers off and look for anything obvious. If a valve spring cap has popped off or something then the cylinder head is going to need to come off I'm afraid. You'll probably need to get a set of head gaskets assuming nothing else is wrong.

Well, after an overdue wait, the garage is being ripped to pieces tonight and so is the CBR, I am determined to get this bike running and to a respectable state.

oh no, the CBR may creep ahead of the CR250!

Cam/head cover off, cams off, camchain loose, still no full turn.

The plungery type things (that's all I can call them because I don't know what they are) that the cams push down all seem about the right height, but might take a picture to let peeps on here decide before I take the head off.

If there is nothing wrong up there that can be solved without removing the head, it'll be.........

'To the the bottom of the deepest deep SON!'.

Those er 'plungery type things' are the valves I really dont think you can do enough damage by placing an engine on its side that would require removing the head, assuming it was turning freely beforehand.

When you say that it doesnt turn, what kind of resistance do you feel? Is it a sudden mechanical stop or the feeling of turning against pressure?

If you havent done this already (cant remember now) then I would be tempted to remove the spark plugs the clutch plates and the oil filler cap. If it doesnt turn now with a spanner on the crank then there sounds to be something serious in the way.

+1, it is possible to have filled the cylinders with oil and be hydraulically locked.

Its a mechanical stop, like someone had just rammed a brick in the way. Clutch plates are out already.

Checked hydrolock already Druid, there is no oil in the engine now, side casings are off etc.

You tried it with plugs out though?

Plugs are not in.

It's f###d then.
