    SHO Cruiser 2008 Engine Specialists - please help

    G'day everyone.

    Went for a ride on the weekend, everything on my SHO Cruiser performed really well as usual, no problems at all.
    At home, performing my usual cleaning/flush procedures, I came across something that I am certain was not there before. Please have a look at the attached photos to see some grease coming out of each spark plug cover. It definitely is grease, really soft & smooth.
    I am positive that I have not seen this before, but wanted to double check with you Pro dudes who ride alot more than I do.
    IS IT NORMAL OR A PROBLEM??
    I had no performance issues or any error lights etc during the ride. SHO Cruiser on 20hrs.

    Many, Many Thanks. Appreciate any advice.
    Cheers, Wazza - Melbourne Australia.

    Cool

    I could be wrong but on those stick coil caps they had problem with rusting in the head,most likely factory/dealership applied grease to stop that and the heat just worked some of it out

    Grease was probably applied to the coil boot to seal it in the well. I know VX is terrible about not sealing and water leaking into the well when you're washing the head cover off after a ride.

    On my SHO I always put grease all around the boot to make sure it sealed.

    Now how the grease got out of the well is something I don't know.

    Maybe a plug is a little loose and blowing some compression out along with the grease?

    Thanx for the advice guys. Really appreciate the ideas.

    Would it be a good thing to take the covers off & re-pack that grease back where it came from?

    UPDATE......

    You guys were spot on. Just got an email back from Yamaha service. The grease was applied at the first 10 hour service to properly seal the plugs against moisture. Turns out there is nothing to worry about.
    So, if anyone else sees something similar, dont panic, its all good.

    Thanks alot for your input fella's.
