we put a washer behind the gear that connects the 2 CIMs together. it did help a little bit but the 4:1 gears were constantly grinding against the dual CIM adapter where the screws hold the 2 together. and adding enough washers to keep from grinding would have pushed the gear to far forward it wouldnt be connected to the CIM gears, or the would barely be connected and cause just as many problems.
