I have heard that it raises the jugs up 2mm and puts the port timming at 130 degrees, just wondered if any one has tried this and if they saw any noticiable gains.

A friend of mine has done this on a 2000 mxz 700 and it work well. We had the same sleds both stock. Mine would pass his till he did this mod. Now he go`s past me with no problem. He got his setup from Larys in Orangevile.

It works, but only works well if the piston rings are sealing properly.
