Does anyone know how to change the dome on the HPD Billet head. I am running the 14.1 dome and am upgrading to the 15.1. Is it as simple as puling the dome out of the head? HPD did not send any instructions.

--Thanks Davesp

 

Pretty sure it is. I've got the Hot Seat head and the dome just pops out (with a little persuasion).

 

Yep. When you get it off just put an old spark plug in it , flip it over and press it out. Take note as to the positions of the water ports. The large port is suposed to face the rear. And grease the o-ring a little when you put the new dome in.

 

yes and that it's done that way,and you'll never be so happy with the mods you have done it,,be ALWAYS sure to run 110 or so octane gas,
and remember to re-torque the heads bolt after the first hours to
make sure it is enough tighten and sealed,get you a pwk 39 and filter charger and you won't beleive what it deliver then.

 

Worked great. Just left the old spark plug in and pressed it off.

I have the 39 PWK and twin air clamp on ..

Thanks....DaveSP

 

The point for others (your's is already back together) is to always make sure to replace the o-rings. Very cheap insurance. And yes, the power "step-up" is a fun one. [img]i/expressions/face-icon-small-smile.gif[/img]
