It was for a CF250 not a CN250. Strange that the clutch size would be different in a cloned cn250 engine, but the bell size and clutch are about 2 centimeters larger in the CF250.
The Dr pulley clutch is bigger than stock. The CF250 Clone and the CN250 will take the same clutch. That clutch would have worked wonderful on your Helix. It will also fits under the belt housing great. The size of the bell housing does't make any difference as long as you have the right clutch matched to it. The Clones do have two different size clutches that they were shipped with but either will fit the Helix. So will the DR pulley clutch made for the CF250. Most High performance Clutches are going to be BIGGER yet lighter than stock
