    Need help again GP800R
    I just rebuilt my engine top and bottom
    the crank seized fron rear cylinder lean condition
    I didn't found a obvious cause so I when prenix set up 32:1 I ride it for 1:30 minutes using the breaking steps 15 minutes rides and resting for 30 minutes etc.
    I check the plugs and this is what I found
    The right one for the front cylinder
    The left for the rear
    They look a little too white for me I think but I new to 2 strokes premixing
    The front one seem to dry

    From what I can see they look brownish which is good. White Lean Black Rich. I run mine a little on the rich side and premix my skis. Sometimes it's hard to tell from pics. How did the ski perform?

    You need to ride the ski wide open for a few seconds then kill it and pull the plugs right away. That will give you a better indicator of how rich/lean you are.
