please help me understand what makes a ratio rocker better and how it would effect fuel signal for low RPM motors?
yep,, saw that,,, which is why i'm asking,..anyone know for the non hemi what motor the 1-3 or 1-2's would come on.. just seams to make sense that the parts were from a bigger or different brand motor. will i need to jet up because the valve will be open longer?There is a video that goes in depth over it.
As far as i know they didnt come on anything, they are aftermarket.yep,, saw that,,, which is why i'm asking,..anyone know for the non hemi what motor the 1-3 or 1-2's would come on.. just seams to make sense that the parts were from a bigger or different brand motor. will i need to jet up because the valve will be open longer?
The 79cc predators have them.yep,, saw that,,, which is why i'm asking,..anyone know for the non hemi what motor the 1-3 or 1-2's would come on.. just seams to make sense that the parts were from a bigger or different brand motor. will i need to jet up because the valve will be open longer?
I got those SUPPOSEDLY 1.3 rocker but they are just shorter rocker OVERALL. if look, at them they are just SHORTER OVERALL and not right. they push on the very very inside of the valve stem as, "something got lost in the translation" when they told china to make them. china understood... "make a smaller/shorter rocker" and that is what they did.
they did not understand, make the pushrod pocket CLOSER to the fulcrum by x amt, but LEAVE THE DISTANCE FROM THE FULCRUM to the VALVE STEM ALONE!!! so what u get when u buy a $10 stamped steel (SUPPOSEDLY) 1.3 rocker is just a SHORTER OVERALL rocker that pushes on the very inside of the valve stem that puts a horrific side load on the valve and doesnt /cant give the valve any more lift.
just very very poor quality control . put the stock rocker on a head and the (supposedly) 1.3 rocker on the other valve (intake, the exhaust flows well enough with stock rocker anyway). and u can see what i am talking about. put them side by side. with the FULCRUM lined up. the supposedly 1.3 rocker is just a SMALLER ROCKER, when it should have the same distance from FULCRUM to valve stem distance and SHORTER pushrod pocket to FULCRUM DISTANCE. poor quality control for a 10 cent stamped steel rocker.
So the 79cc predators come with 1.2 rockers is this correct ?The top is from a 79cc predator. The bottom is off a clone.View attachment 12185
