Default Starting the motor

I am looking at an 80cc motor here and I am wondering how these engines are started

it says you can do pedal starts and so on
I was thinking of removing the pedals all together here

are they pull start or is there an ignition key? I am completely noobish at this but I appreciate any and all help. thanks

You need to peddle to start but there is a pull start available for around ten bucks or so.
You also need to peddle the bike to get going with these kits unless you get a jackshaft kit from sickbikeparts. It allows you to use your rear gears but you need to keep your crank in place. I just tried this morning and I can start off in first gear without helping the bike to start off.
Why do you want to remove the peddles?

the only time i hated my pedal start is when something was wrong with the engine. usually it was a clogged fuel line or out of gas but still it is a pain.

Check your local laws pertaining to motor assisted bicycles. If you remove the pedals, bad idea, then your bike will not legally or technically be a bicycle anymore. It could fall under the heading of a motorcycle. In additon to the laws, having the option of pedaling can be a blessing in the event you have mechanical/engine problems far from home. Most will agree here; Keep the pedals.

I am going to keep the pedals, i bought this 80cc kit on ebay and I am wondering how a pedal start works, do you pedal then hit the yellow throttle switch to fire the motor?

The botton is your kill switch to turn the motor off. To start you "bump start" it.
You start to peddle and when rolling you pop the cluch and the motor starts.
It's very simple.

Toytime,
That is a great site. It should be required reading for every new member and even the old timers might pick up a thing or two they've forgotten over the years. It should be posted here someplace that is apparent and easily located by folks just getting started or are contemplating getting into this hobby. I copied it to 'My Favorites' for quick reference. Thanks for posting it.

exactly what I needed, thank you a lot one more thing....

when I look at the small sprocket that comes right off the engine, you can't turn it by hand, it is like it is in gear or something... do you just need to hook the chain up and pedal it? That is the only thing I am really unclear on, I appreciate the help

When you are looking at it you have the clutch cover off so the clutch is engaged. You could use the included spark plug wrench to turn it, but by hand you just aren't strong enough. BTW that is a good way to feed the drive chain onto the sprocket, with that spark plug wrench.
