Honda VFR750R RC30 fuel tap diaphragm delete.
HRC recommended modifying the standard fuel tap for track/race use. However the modification retained the standard diaphragm which in many cases caused trouble. Many pattern and aftermarket diaphragms are too stiff to control the taps function properly causing yet more issues.
These delete plates, complete with O ring replace the whole vacuum side of the standard fuel tap.
