The picture is worth 1000 words. He uses the valve compressor fork in his drill press but only use's it as a press. He puts a cloth on the drill press table (Hopefully). Pulls the press handle and that will push the valve down untill it hits the cloth, compressing the spring using a magnet to remove his 2 peice keepers. Its hard to do it yourself without a one handed press.

How many times must you fail in a day?

Lol I dont think hes going to turn it on. Also Oscar, wasnt that head port and polished by Shane? Doesnt look like it to me going by the photos.

Safety first! Even know he probably wouldn't turn it on on purpose, he might swing a screwdriver wildy across his head, hitting the drill press and throwing the head into his mothers car. Thus shattering the head and breaking his mother's car window. Then after the head makes it threw the window, it would hit an impact panel and be thrown by the air bags out the back window! From there they would hit an old man on a bicycle. The man would fall down and have a heart attack. A women would see him across the street and run over to help, but only to be hit by a garbage truck...
Now image if only Oscar would have unplugged the drill. That would not have happened!

I've seen a Junior Dragster 3 pound clutch fly off at 8000 RPM and go threw a cars windshield. I've also seen a grade 8 bolt shear from the slamming action of the clutch. Clutch flew off the end of the crank and rolled and bounced all the way down the track to the 660 mark.
he had a link to some website selling heads so DONT CALL ME ANOTHER FAIL OR I WILL UNLEASH THE FLEAS FROM ATHOUSAND CAMELS ON YOUR CROTCH.
Oh yeah, Photobucket didn't copy my link >.>
And I was asking Tyler on MSN if that head would fit my 36cc scooterz.
Oh and I turned it on to see what'd happen. Nothing happened lol. I use the a bolt to hold the little compressor to the chuck.

You asked me if the 200 head would fit your 36cc scooter?
works like a dream for disasembly
i used a oem brand door panel tool to compress the springs in a flatty. slip the keepers in place, drop the valves in. use a flathead to tweak the keeper so you can get the door panel pry bar in. compress the spring while pushing down on the valve, manipulate the keeper.
i used a bs drill press for regular drills to do mine (on ohv). in dealing with some of the bike valvetrains with duals, and split keepers i use a longer pry bar, similar to the one hand compressor. spring tension? who knows but the are stiff, you could stand on em and the would maybe move.
Get some PB Blaster on it, get some heat, and then after that, remove the rod and piston assembly, and the camshaft, side cover...
So the crank can basically come out. Get a 2/3 jaw puller, attach it to somewhere on the block, and keep turning till the crankshaft pop's out.
Might put a BIT of stress on the flywheel, but not too much IMO.
Used it to pop a press on clutch off on a cheap 49cc 2 stroke.

What if you were to use an air chisel instead of a puller? Hold it over a pillow of something to catch the crank.
