dificult to see, but front and rear valves open at the same time ?
when are the 4 strokes suppost to happen when the valves open each revolution ?
if it runs, you can race it !

Yes first the induction side and then the exhaust side on a four stroke ------This is a double lobe cam and open one behind the other at 30 deg apart for all in one rotation

What 4-stroke engine are you using?

When will you be testing the new design?

Sounds like you've turned a 4-stroke into a 2-stroke.

Not sure I understand, but I like it!! :smt023

The Donor Motor was a CBR250R which keeps it the FIM range for the Class
It has alot of other different links and hopefully next two wks the new ECU will give it a try -fingers crossed
