Yamaha YZF R125 top end barrel cylinder piston removal 

Removing the top end is easy the only thing to remember is how to set timing on rebuild which is not difficult .

Remove the rocker cover bolts 

this exposes the main cylinder head bolts

Remove water pump see our post here on that 

these 2 allen head bolts need to be removed as well 

Here I am holding the flywheel bolt to undo the timing chain 

bolt .

below the timing chain tensioner is loosened and then  removed 

you can now free the timing chain i hold it with string to avoid dropping it into

engine

I have now removed the timing chain sprocket as I needed to 

and I am undoing the top cylinder head main bolts 

pulling head free while controlling chain 

now remove chain guides 

and prepare cylinder barrel for removal 

again control chain while lifting of barrel
