3/32 chainrings should be compatible with 1/8th chains, but 1/8th chains are not compatible with 3/32 cogs. you can either buy a new 1/8th kmz chain...its like 10 bucks at walmart. you can also buy a 3/32 kmz chain from there for like 5 bucks.
or you can replace the cog to a 3/32 for 15 bucks....
if you plan on replacing your cog...i'd be interested in buying it from you if you want to sell it.
