    Read my plug

    I pulled the plugs on my 95 900zxi. They are black and shiny. I know this pic isn't very good but can you give me an opinion? Lean? Rich?

    Thanks,
    Rob

    Its hard to tell from the pic because I cant really see the electrode. It looks to be rich from what I can see but compare it with these and you will get it right.

    Thanks alot for the link. Looks alot like #1. They are not fouled and the ski runs fine. I just pull the plugs once in a while to check on things. I am getting ready to switch this thing over to premix so I will see what they look like after that.

    It would be better to read the plugs from a chop. Mine look like that from idleing through no wake zones but when I chop it they are perfect.

    Yea, this was not from a chop. I am just not sure that I can get the seat off, and pull the plugs with out upsetting the ski. This thing is pretty unstable with my fat arse on it. I will have to figure something out.

    Aim it at a spot where you can beach it then kill it at the last possible moment. Shallow spots work too I have done this frequently lately been working out some carb tunning issues with my ulta 150.

    Looks fat but I agree you need to check it after a clean run and shutoff.
