This makes the chain track much better. I like the 80cc motors best.
Not necessarily true. I have 1 Grubee 66cc that has a thicker sprocket/chain, 1 66cc Grubee that has a thinner sprocket/chain and one 49cc that has a thinner sprocket and thick chain.

Thin sprocket can use either the thin or thick chain. Thick sprocket can only use thick chain.

Personally, I prefer the thin chain as it quieter, less drag when pedaling and smoother- but that's just my opinion.
