So I was stupid and blew the engine. Had to rebuild it minus the crankcase. I was wondering what all I need to watch out for. I already have the cylinder head on and it turns over well and I am 99% sure i have it timed correctly.

Problems arised though. It was raining and some rain got into the cylinder head and when i turned it over it came out, no more will come out though except for maybe a couple specks. Its a really gross brown too. Do I need to take my head off again to clean it out?

Also rain isn't the only thing that got in their. A couple of really small pieces of some really thin bark got in their and they are smaller than your fingernail. When I crank the engine over will they burn and turn into ash and get taken out of the exhaust or do I need to take the head off for that as well?

If you have the tool set that came with the bike, there is a plug socket in there that will work.

A hardware store that caries small engine tools and parts should have one. Also, check the plumbing section - a similar tool is used for sink faucet installation. Bring your calipers.

Take a blower & put a piece of 1/8th brass tubing on it, Blow on top of the piston & try to make the airflow develop "Headin OUt the plug hole",, that can carry stuff away,, YOu can fish the little bits out with wire & a dab of grease.. Sure would suck to spin it over & jam somethjing into the rings & mess them up,..,

I got a deep socket set from HF and it works just fine.  It looks the same size as the ones they sell at the auto store.
