I made a custom intake for my stock A55 carb to fit my custom bike. The tube is chrome from an abandoned shopping cart. It's a bigger ID than the stock tube. Initially it will be attached to the stock carb. Later to a 19mm Dellorto PHBG.
1) Will the increased ID of the intake have any negative effects while using the stock carb? I shouldn't think so.
2) Must I use some sort of rubber hose like the stock unit or can I fabricate a bracket/flange to be used on both the stock carb and the 19mm?
