Cross over intake fail

John has this ever happened on any of your other cross over intakes? Trashed the valves on my rear head.

Nova, my son has been riding it and was complaining that it was hard to start. I finally had time to check it out, went to set valve clearance and could not get any on one intake in rear head. Pulled the head and noticed dirt in the intake, I'm holding it apart in the pic but otherwise was very hard to see when mounted. Dropped the head off to machine shop and they phoned back once disassembled and cleaned saying I need 1 intake valve, grind the seats, valve guides and seals. I have a set of rings and gaskets here so will hone the cylinder and re ring while I'm at it. If you look at the pic the Orange rubber/urethane looks way to thin where it moulds over the alloy flange?

Yes it does. I would advise anyone who has a set to check them before its to late. Very hard to tell anything was wrong with it because of the way it fits between the two heads but once some twist and movement is introduced like when on and off the throttle that's when you'll suck dust and shit in. If it was a single intake like twyztid is talking about it would be much more noticeable but the design of the x overs is a tight fit and the x over tube supports both intake runners.

Ah ok, I didn't know that, thought he had them made elsewhere.
