Product Description
Flat mount intake works perfectly with Bing carburetor. A SHA or Amal can be used with some custom shimming.
Used on Sachs 504, 505 A and B cylinders that have the angled intake port along with the Athena cylinders. Two angles don't make a right. Use a flat intake on a angled port. Visa versa. Got it?!
