I noticed on the RIVA motorsports web site that the 2 cam bearings on the 400ex cam are of different sizes. They say that the bearing on the side of the cam with the chain is a 18x37x9 (18mm bore diameter x 37mm outer diameter x 9mm thickness). They say that the bearing on the side of the cam without the chain is a 20x37x9.
This doesn't exactly sound true. Also.... I've tried several bearing sites and can't find any 18mmbore bearings.
Does anyone have those specific measurements? I once had to tear into a 400ex head and they sure looked the same to me.
