My adaptor arrived back home today. Now its nice and balanced and smooth. No more wobble. Problem fixed and any new adaptors will not run into this problem with aftermarket flywheels. Main problem is that the back side of the flywheel is not consistent with different aftermarket flywheels. The issue was resolved by trimming off .050 off the back side which is not critical, or perfectly flat as it does not sit on anything. But if the foot is too long then it bumps the bearing and the face that seats on the shaft is not touching properly. All new adaptor plates will have the bearing set back by .050 to allow for the different sizes of adaptor plates so this issue never arrises again. Never saw that one coming. But thankfully its resolved. These adaptors are super nice and reasonable in price. Built to last 10 lifetimes.
