And the idiot of the week award goes to.................................me!!

I used the "pencil in the spark plug hole" trick to find TDC (I know I read about doing this somewhere) and yep, up came the piston and snapped about 1/2" of it off. :thumbsup: :thumbsup:

Any suggestions on a *easy* way to get it out??

The idea of tearing the whole engine apart is not at all appealing and probably beyond my mechanical ability to attempt alone.

ANY help is greatfully received.

Pick the bike up, turn it upside down and shake it around a bit.

Seriously though thats sucks...try to get one of the "pincher picker upper tools" know the one i'm talking about, you squeeze the handle and the three little prongs stick out. That tool has saved me a lot at work. (apprentice auto tech)

Other than that i dont have any suggestions, agh...big bore kit while the head is off ??

I've know of a guy who dropped one of those little metal spark plug caps into his cylinder before and that is how he got it out. Three guys turned upside down and shook it till it fell out.

10-4 on the big bore.

Get another pencil with a piece of sticky chewing gum on the tip.

Take the header off and put it to bottom dead center, than pull it out of the exhaust holes

Or if all else fails, just remove the head. It's really not that difficult. You can do it with the engine in the frame so DON'T remove the engine.

You know that there are timing marks under the left hand side engine cover accessible by removing the allen-head cap plugs that will let you get to TDC without sticking anything into the spark plug hole.... right?

Do you have a 600, or the 650R? If the 650R disregard everything I have said as I have never worked on one, and don't know anything about them.. Sorry.

The easy way to handle this is to figure out a way to magnatize the carbon in the pencil and then fish it out with a piece of thin steel.:thumbsup: Just kidding; hope u get it out.

Dick you know better that would work with a 2 stroke but a 4 come on man the pencil would have to make it's way through the valves first and I can't see that happening ."Thumper"

I used a flat headed screwdriver to find TDC, its almost impossible to mess anything up with that.

I never understood why everyone thinks it's so critical to get the piston to TDC on the compression stroke. It does not seem necessary to me... just take the valve cover(s) off, turn over the engine until the exhaust valves close, turn it a bit more just to be sure they're completely closed, hold the crank still somehow (so the engine does not turn) and adjust them. Turn the engine over a few times and double-check. Done with exhaust valves. Do the same for the intakes. It always worked fine for me... call me :thumbsup:

screw it. Put the plug back in, kick it over and run it till the pencil burns up...i bet all you'll notice it a bit more carbon coming out the tail. Glad to help.

oh and next time try using a crayon, one of those tick ones that wont snap so easy.
