YD100 porting help. Has anyone ported a YD100?

[Zer037]

I'd like to Port my YD100 Dio reed kit OKO 21mm carb and MZ65 pipe 36T sprocket.

How many millimeters should I raise the exhaust port on the top?
How many millimeters should I widen the exhaust port on each side?

How many millimeters should I lower the intake port on the bottom?
How many millimeters should I widen the intake port on each side?

I have not assembled it yet.
What is the top speed of the YD100 36T stock, without the Dio reed kit and without the MZ65 pipe, non ported, just stock bare bones kit top speed?
What is the top speed you think I can get with the Dio reed kit, MZ65 pipe, 36T, ported on flat roads?

I'd just widen the exhaust a mm or 2 and match the intake to the manifold and call ot good. Those motors weren't meant to be tinkered with to much. Pretty much for those who want a little more power, but don't wanna tinker. Get a 79/100 motor if ya wanna tinker. More power than a yd100 too. An if your going dio, dont wast time with a mz65 clone, get the real deal or a dirtbike pipe and make it fit. The mz clone is to small for the yd100 with a dio and port job.
