Snapped pencil down spark plug hole.

[Bambam3]

Really.

Was trying to find TDC, used a pencil as a guide so I could see it rising as I had nothing long and thin, then it got caught as the piston rose and snapped in there.

I feel like crying. I just needed to adjust the damn valves. Arhggrhgrhghrgh.

Anyone know whats next or what it's gonna cost me to get everything stripped out and remove the pencil bits from in there?

Absolute nightmare, I'm at my wits end.

What bike is it?

A Honda XR125. Same engine as the Honda CG if I'm not mistaken.

You could always flood the cylinder with oil, then turn it over, with a socket on the end of the crank. The piston should push out the oil and the pencil bits along with it. Or make it reachable with some tweezers/chopsticks.

It will run rough though when you start it up again though.

should be too difficult to remove the head & extract the debris.........

It isn't a CG engine, it's an OHC engine. CG uses pushrods.

Get some tweezers, a strong torch, and some patience and fish the bits out of the hole.

In future, use the workshop manual. TDC is marked on the flywheel, you take off the inspections caps on the left hand side crankcase cover and use the big one to turn the crank while you use the small one to look for the T mark.

Tiny wood fragments shouldn't be an issue really as they will be burnt and turned into carbon anyway. Make sure you get all the lead out as graphite could possibly be very bad for valves.

Hoover?

No, if you look down the plug hole with a torch and turn the engine over you will see the valve moving across the plug hole, this is probably what broke your pencil, only use this method on a 2 stroke. Your engine is a small bore version of the modern (ish) cg150 engine and is a pushrod ohv model. The cylider head is very easy to remove and your valve timing will not be upset by doing so.

just run it up with the pencil bits in it. It wont damage it, and it'll get broken up and spat out in its own time.
My ktm ran for a while with half an aluminium carb slide sucked into the cylinder and there was no damage whatsoever after lifting the head when it finally clattered to a halt.

Can I ask what you are trying to do to the bike, are you trying to adjust the tappets?

[Bambam3]

Op, its really easy to do without timing marks. just turn your engine over until the exhaust valve tappet clearance is at its maximum (biggest gap) then set to the proper gap. repeat the process for the inlet valve and do the same but you WILL need to remove the cylinder head and remove the pencil you have no option or risk wrecking the engine.
