I have found so much great info in the archives at VAF that it suprises me when I have an issue that haven't been addressed yet. Well here is one I did not find.
I am ready to fit the filtered air box to the carb. The carb is a new MA-4-5 from Van's in 1999. I understand that I have to cut a hole for clearing the rear drain but I have additional interference along the rear edge of the mounting face due to a lip that goes across the full width. If I were to notch the top plate of the air box for this lip it would be so close to the bolts in the rear that I fear it will easily crack. On one side it looks like I can file the lip down. On the other side I can file the lip down a little to the body but it will not be flush with the mounting face for the air box.
The Questions I have are:
1. Have others had this issue? How did you handle this?
2. Is it OK to file off the lip on the carb?
3. Is there a gasket that should be used between the carb and the air box top plate that can take up offset at the rear?
4. Has anyone used a spacer allow clearance over the lip at the rear?
Thanks for your help.
