I have a chainsaw motor with clutch sprockets of about 5 1/2 cm i believe apart from each other. my bike that i want to mount it on has a normal bike sprocket on it. i want the thing to be chain powered and wondering where can i find a big enough chain and sprocket for the bike.

the clutch on the saw is half inch spacing and quarter inch spacing on the bike, a normal bike chain does not fit on the chainsaw

Hmmmm....
All modern bicycles use 1/2 inch pitch, #41 chain.
The chains are available in 3/32", 1/8", 5/32" or 3/16" roller widths, depending on the use.
Your bicycle seems to take a #25 chain, very odd.

What is the width of the chainsaw sprocket?
Was the bicycle you plan on using once an electric bike with a chain drive or something similar?

I used to have a flock of chainsaws...
They come new with what we called a paddle-wheel, that we pitched and changed out for a drum and rim. Both engaged the 'fins?' on the inside of a chainsaw cutting chain which are NOT found on any bicycle chain.
IMO it would require a sprocket welded to whatever drive mechanism is furnished on the chainsaw.

Has Cannonball2 been here yet?
He probably knows all bout that stuff.
