Chains

[Demon Speed]

I'm planning on installing my pocket bike engine on my bicycle. The problem is the chain. The chain on the p.b. is a lot smaller than the standard 415 chain that comes with the bike engine kits. My dilemma is trying to determine the size of said chain. Is it a 25 H or a T 8F ? I have no no idea,if someone can help me out with this it would be greatly appreciated. Thank you

Change the sprocket on the engine to match.
