Something happened at the meet to the CVZ that has me somewhat confused. After nearly getting swamped at the pit by a big river boat, the Z has a noticably louder exhaust note and has trouble holding an idle. Was finally able last Wednesday to hook it to the hose and it definitely sounds different. Pumps very little water out exhaust on port side at idle. Pulled plugs and exhaust, didn't find anything unusual. Checked timing, was way retarded. The dizzy has a separate lock down to set timing inside, so it's not adjusted by moving the dizzy body. This keeps the flat cap aligned. The internal screw loosened up and allowed timing to retard. Likely just a coincidence, but happy it happened at end of event. So here is my question. I run maybe 130 degrees, thermostat is 190, but appears to only dump in exhuast. What kind of temps do the rest of you run?
