    Hotter plugs

    Well I have just been getting educated by ZMANN and talking with a friend of mine. The plugs I had in my sl650std were BR7ES and the ZMANN told me to switch to a BR8ES, a hotter plug. Would that help with it seeming flooding out? When I pull the current plugs, they are black but not wet. So I am seeing if I got this right... with a hotter plug, it will self clean and not come out dry and black... correct?

    BR8ES is not a hotter plug, BR6ES would be a hotter plug than a BR7......
    NGK down in number= hotter plug

    Champion up in number=hotter plug


    And, I would not just go to a hotter plug, that alone can cause some serious heat damage at times.

    If it's running rich, you need to dial it in with jetting.

    ^^^what redline said...if anything you want to run as cool running of a plug that your engine will run on. Adjust things with your jetting...although it dosen't sound like it needs it. Can you post some pics so we can see what ya got?

    Sorry HotPatato I thought I made it crystal clear it wasn't a hotter plug just a safer plug ( recommended for this application) and you should dial your carbs in using that plug! Z
