Just a bit oil, cleaned off and there's nothing there.

All gears and teeth are fine.

The conrods don't look obviously bent but I guess it would be difficult to tell.
It is tighter when pistons 2&3 are down (compressed) and fairly loose when they are the way out.

So can I get to the pistons / conrods without opening the top end or is it now major strip down?

Have you got the head off?

Or the cam off?


If not. That may be the reason it is  difficult to rotate.

The cam opening the valves

If you want to lift the crank out you can remove cam and rockers to let the cam chain drop down to crank,  then undo conrods/ big ends and lift crank out

You dont have to disturb the barrels and head at this stage.
