I am considering a 4253 enhancer ignition for my Yamaha Superjet but had a question:

As far as I know, the older style Yamaha stator and flywheel (61X) had a different timing than the newer style (62T). Which version is your 4253 CDI compatible with?

I have heard that people use your ignition with either version and simply use a ‘gender changer’ conversion wire on the only wire that isn’t the same so it hooks up, but I believe the 61X has a 7° difference in the stator timing so how could it function the same?
There is also a higher voltage with the 62T but it's the timing that I'm wondering about. If Yamaha CDI's are not interchangeable then how could your MSD one be (if that's the case)?
