  • #1 piston detonation zxi 1100 after 10 hours

    I just received my replacement SBt 1100 engine, the 1st one detonated the #1 piston adfter 10 hours. The #1 cylinder was getting very hot, and actually discolored from the heat. I checked the 2 cooling hoses on the magneto cover and they are not clogged. Anything specific I should check on the carbs, since this is obviously a lean condition?

    Also how do I adjust the high and low speed settings on the carbs?

      It is always a better idea to go through the carbs before you install the new engine. So go through the carbs before you get your next engine.

        Can you be a little more specific when u say go thru the carb. Exactly what am i looking for besides dirt and gum. What needs to be addressed?. I just rebuilt them with your kit.

          Remove all internal parts, clean them check jetting for proper size, reset and verify pop-off pressure and reinstall them. Check high and low needle settings and test ski.
