The Story: Bought a Modquad head, threw it on, rode with it for a bit, then top-end time. Pulled the head off and the aluminum lip that keeps the outer o-ring in place bent outwards. Went through alf, who went through modquad. Never heard from modquad personally, so alf sent me one he had laying around. keep in mind that it wasn't certain at the time whether he would get another or not. I will certainly be dealing with ol' Alf for any services he offers that I need. Much thanks.
STAND UP GUY!!
