I took my 2000 ZRT 800 to the lake yesterday. I have been playing around with the jetting and clutching. I believe I have the clutching where I want it. But now have to address the jetting. I have jetted down to 330''s(according to my jetting chart I should be good down to 0 degrees @ ~1,000 ft)from stock 350''s. It was about 28 degrees F and I decided to check my mains by doing the full throttle run and hitting the kill switch. Now for my question. Which part of the plug should I be looking at?. My 2000 Performance manual says to read the center electrode and look for a silver spot on the tip that protrudes down at an angle. The farther down the silver color goes indicates how rich/lean you are. My plugs center electrode only had the silver at the very tip. According to the manual this would indicate a rich condition. But the plugs ceramic insulators were mostly white with a hint of tan color, I always thought this ment lean. Anyone know where I am at?.
