Re: RZ Frame modified MOTO3 project
it s different motor and fires every rotation using cams and injection
Re: RZ Frame modified MOTO3 project
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 ?

Re: RZ Frame modified MOTO3 project
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

Re: RZ Frame modified MOTO3 project
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!!

Re: RZ Frame modified MOTO3 project
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

Re: RZ Frame modified MOTO3 project
To be honest, it doesn't sound like a powerful engine.
It doesn't pick up revs very dynamically.
More like a lame duck that stalls immediately when not on the throttle.
Are there any performance curves available, i.e. is there any gain compared to the same engine being a normal 4 stroke?
