The MBP retaining system was designed to extend valve adjustment intervals by using a superior design to retain the closer shim on the valve stem.
• MBP Retainers are compatible with EMS Closer Shims and Ducati OEM Closer Shims
• MBP Retainers are available for 7mm and 8mm valve stems
• 8 MBP retainers are needed for 2V bikes
• 16 MBP retainers are needed for 4V bikes
There are two 7mm MBP retainer designs. One is for the early 4V and all 2V-7mm bikes, the other is for all later 4V bikes. The later 4V bikes require a slightly smaller MBP retainer (about .0005 in.) to fit properly.
Modified Opener shims are required when MBP Retainers are used on all 4V bikes.
