    Header installation

    Installed my black widow headers and when I removed the stock ones, I didn't see any of the stock gasket rings fall out. My first try tightening the headers to the head, I noticed that they would not get tight even when the nuts were fully threaded. I put the gaskets black widow sends with the pipes which are a lot thicker than typical gaskets and everything tightened as it should. Is it remotely possible there were no stock gaskets installed? This is a used bike with 2,500 miles but all stock.

    They tend to stick to engine. Had to carefully pry mine out.

    Most likely the case here. Since it seems that I have a good seal on all 4 downpipes, any harm in leaving it as is?

    .    I guess if not leaking would be fine but it would bug me knowing I didnít get them out! Someone with more experience will chime in shortly.✌🏻

    Not likely, crush washers are softer + meant to "crush" forming the seal.
    If you got them tight and torqued to spec just do a simple leak test on them with a piece of TP.
    Run it if all good, let the next guy figure it out.   :028:

    I did the same install on my Z900.  The stock gaskets are very thin, and you have to be deliberate about prying them out if they stick.  I made a vide about this, and the specific part about removing the gaskets start at 9:12 in the video:



    I know you don't want to rip all of that stuff out, and unless you determine it is leaking, it may be ok.  Hopefully this helps the next person doing this swap.
