comments on cylinder

[250R_SV]

Hi
Here are some pics of a cilinder I have sitting in my garage, its ported, can you give your comments on it?!
Im planing on putting it later on my quad.
Right now Im running a ported cylinder with spacer but doesn´t look as good ported as this one. Im running it with a fatty and a 38carb.

Thanks

Some porters will add those holes, in an attempt to promote more intake flow & to some degree copy the Pro-x cylinders.
Just one of the 100's of little things you can do to a 2 stroke that when all bunched together will add hp.

Can you take a picture of the inside of the cylinder from the top looking towards the intake port? Rick drills those holes into the rear transfer ports, the holes on your cylinder look a little different...
