    I would use the good ol HD Intake gaskets they work fine and you can pick them up at the dealer locally, or any independent shop will have gaskets.

    Some folks use Hylomar gasket sealer with the seals but I've never done it.

    If you don't have a Service Manual for the bike and you are going to start doing work on it I'd suggest you get one from the dealer you will see all the parts, how it comes apart, together etc.

    this is not a difficult job but it's got its PIA parts.

    I usually do the following

    Put bike up on jack
    remove seat
    disconnect fuel lines from tank by pulling down on the chrome skirt to disengage the lock, be careful there are o rings inside and you don't want to fubar those, and they can be a little diffcult to remove but they will pop out
    Remove rear gas tank bolt
    Put towel on front of tank
    Lift rear of tank and slip the cap off a spray can under to hold it up
    Remove air filter cover, filter, backing plate and head breather tube
    Remove horn
    Loosen throttle cable adjusters completely at throttle
    Remove electronic connectors from throttle body, sensors and injectors
    Remove rear allen bolts on intake replace with standard hex head bolts same size makes it easier (don't put the new ones in yet
    Remove front Allen Intake bolts don't change them over to Hex
    It helps to make up a tool to get them out I cut down an allen ball end to about 1 inch long and use a tiny open end wrench, it helps

    Now you can pull the throttle body assembly out, remove throttle cables from assembly,

    Remove seals and intake flanges, take note one should have an R on it for rear and the other an F for front.

    Clean up area
    Reinstall flanges and slip on seal
    Reinstall throttle cables
    Loosely install the new rear hex bolts by a couple of threads
    Slide the intake with flanges into the area and guide onto the rear bolts
    Adjust intake up and align bolt holes and install front allen flange bolts
    Tighten bolts and keep intake level and aligned
    Reinstall connectors use di-electric grease on them
    Adjust throttle cables properly
    reinstall fuel line to tank
    Horn
    air cleaner
    tank to frame
    seat
    then start it up.

    Use dielectric grease, found at auto parts stores, I have heard of other people doing that on there pc3, water must be an issue in the plug ins with them. Todd

    As far as adding a sealant to the intake gaskets,
    I've had good success with something called
    Curel-T. Porsche mechanics use it for intake
    related sealing on those motors. You might find
    it at there parts counter, but I've gotten it online.
    It never hardens, but stays kinda sticky, and does
    not fail under vacuum loads.

    You cant really use to much, It will just squeeze out, Im sure that tiny tube costs a couple of bucks, I work at a shop so whenever I need some I just use the shops so I cant tell you the price, Todd
