I'm looking far into the future for a summer project and am thinking of trying to put together a motorized bicycle from home parts. I've been searching the net trying to find some guidance, just so I don't kill myself, but I'm having difficulties. I'm searching for ANY help, plans, possible parts, past experience, anything. Thanks!

Motorizing isn't the problem. The problem is that there isn't a bicycle out there that is safe at a speed faster than what you can pedal and mostly because of the poor quality of the brakes with which they're equipped. When I was stationed in 'Nam they had some hybrid bicycles which you started off pedaling and then pulled a lever which dropped a small motor down so the small wheel on the motors output shaft contacted the front wheel of the bike and turned it. Even though it had a better braking system than a standard bike I saw a lot of young ladies (which was mostly what rode them) taking some real nasty spills when they couldn't stop in time at intersections.
Also a buddy of mine, back in the early 50's had a motor bike which was built by the Schwinn Corp. It used a belt drive on the rear and had decent brakes, similar to a motor cycles.

Simple is better. Mount a small 2 stroke on the frame with a minibike clutch on the crank. Run a chain from that directly to a sprocket on the opposite side of the wheel from the original sprocket.
Gear it for high speeds, and simply pedal the cranks to start from a stop. When you get moving you can hit the throttle and stop pedaling.
I've seen a kid ride by my shop on one like that and it looks great, fast and quiet too.
I built one with shocks, with no pedals and 21 speeds but it's a tank with too many things to go wrong, and when it does go wrong you're pushing.

Its going to be pretty hard to do that... bikes have a high centre of gravity so adding weight to it will make it difficult to ride.
Might be a better idea to find an old moped/scooter or motorbike and strip it down, then customize it.
I know it doesn't really answer your question but it would be easier to alter an existing bike than add parts to something that isn't really supposed to have them.
Good luck whatever you do.
