manic adaptor sprocket and chain trouble

Hi. I am installing a new 88 flying horse motor and I decided to spend the extra bucks on the manic adaptor and 44 tooth sprocket. It stated the 415 chain was needed for the manic setup which is no problem because the kit comes with a 415 chain. The adaptor and sprocket installed easy, however the chain will not go all the way around the sprocket it comes off about half way around the sprocket like the chain links are too short, but the chain wraps perfectly around the sprocket that comes with the kit. I'm stumped because it states it only works with the 415 chain. Anyone else have this problem? The dealer is closed on Sundays but I could use some advice today. THANKS

Hi. I ordered this at Bikeberry and a 44 tooth manic sprocket because the kit has a 44 tooth. If I have to I can drill the kit sproket to match the adapter and send back the manic.
