    Lost rpm in fzr svho 59hrs

    Ok so today i try to do a speed run usually its at around 7500rpm and today the ski would not pass 7k rpm, one time it wouldn't pass 6k. i did a few runs, but never hold the wot to long afraid i was making the problem worse. decided to check the spark plugs and wen i took the cover off notice moisture and water inside 3 of them. imma clean them out before i change the plugs, don't wanna pull the plugs and have water or dirt go inside. oil changes have been done at 10hrs, 25hrs, and 50hrs.
    1. Do you think that could be the problem?
    2. why would i have water in there?
    3. a friend said i should put grease around the rubber so water won't go in.

    Looks like it may have been submerged at one point. That valve cover is disgusting.

    No, never submerge or flipped. I shower the engine with water never high pressure, just shower after I use it.

    How else would I flush the outside of the engine, would the grease around the rim help. The valve cover just looks like that cause it has a heavy coat of LPS3 rust inhibitor.

    wow....everyone telling you that your vale cover is dirty cracks me up..none of it is relevant but it sure is kinda funny...


    This is all totally normal stuff, just pull your old plugs and put the new ones in, that little bit of water isnt going to do anything
    get a high temp marine lube and smear it all over the coils when you go back to put them in, rotate them as you push them back into t get it all Also make sure that you put some on the top seal as well. This stops water from coming in and allows them to come back out later on
    Replace your air filter if you have not already.
    Pull off your injectors and spray both sides with carb and choke spray.
    choke spray.
    Remove your ribbon filter
    and make sure you oil is not over filled.


    if all that doesn't work, remove your fuel pump assembly, and take it completely apart to get to the fuel filter, spray the crap out of it with carb and choke and put her all back together.

    I experienced the same issue with my FZS. I put dielectric grease on the coils and still got moisture in there. I believe it is condensation but I bet your spark plugs are fouled. To prevent debris from getting in the cylinder, spray carb cleaner in the plug well and blow it out with compressed air. The plugs may look fine but they can still misfire intermittently. My theory is that moisture from the exhaust system migrates through the exhaust valve during periods of non use and contaminate the plugs (I know that's way out there but I couldn't see any other reason for plugs to miss like this).
