I just got off the phone with my buddy (RapidoV6) and he said he read somewhere that these BHJ balancers are 3.5 degrees advanced. Is this true? He checked his comapred to a stock balancer and his was off. He also had to modify his crank sensor bracket to make it work. Anybody else have these issues? My motor is just about finished so if i need to have the builder fix this 3.5 degree issue, I better do it now. Are all of these this way?
