VFR 4th Gen Head Gasket Conundrum

Recommended Posts

Hi Everyone. Im in the midst of my very arduous VFR streetfighter build. . One thing that needed to be done was replacing the head gaskets after pulling the top end apart (some crud fell down the intake while removing the 20 something year old carburetor boots) When i received my new ones i noticed a small difference from the original. The stock part has a small restrictor in one of the oil holes - ive pointed it out where it is in this pic - The new parts however, have a full size hole , so im wondering why the difference? anyone know what this particular hole is? oil return/oil delivery? any info here would be swell.

Very few VFR engines are ever torn down for repair...  One of your fellow Kiwis might know.  Can't remember his name, but he's done his own big bore conversion.  Good luck.

 

Ciao,

you might be able to figure it out after studying the very detailed lubrication flow chart and diagram in the FSM.

 

i dropped a carb clamp nut into a gen2 and had to go in to remove it...............
