    780 head gaskets reuseable?

    I'm getting ready to order parts for the top end of my '96 780. I don't know the cause of my lean conditions on my MAG & PTO so I will perform a pressure test to (hopefully) rule out a crank seal problem. My hope is that my inexperience in tuning carbs and reading plugs simply caused me to set things too lean.

    Which brings me to my point. Once I get everything together and set the carbs back to stock settings I'm going to rely on piston wash to make sure I'm set right. I don't have a borescope so my only option is to pull the domes and take a peak. Are 780 head gaskets reuseable or will I need to put new gaskets on each time I pull them?

    I thought it best to ask now before I order parts, that way I can order extras if needed.

    Thanks.

    They can be reused but it is always good to have a spare set ready.

    Sounds good. I'll order an extra set to have on hand.

    So when I reuse them should I first reassemble and then run a compression check to make sure I'm sealed before I fire it up?

    Oh, one more thing, are the cooling rail gaskets reuseable as well? When I pulled the rail, the gaskets all stuck to it and they looked like I could just put a little sealer on them when I reinstall. I forget what sealer I used, but it was whatever SBT recommended in their engine installation guide.

    Sorry for all the Noob goober questions, but I really want to make sure I get this thing right this time. I really just want to ride, not spend my summer turning wrenches.

    Thanks,
    KJ
