I guess I am pretty hard on it lots of WOT runs and I seem to average about 10:30 per tank from full to fumes. The 1130 min mark seems possible with the right driver on a track I assume. This is my first .21 motor so I can't really compare it to anything. My tuning is not the greatest as it took me some time to find the right needle balance and eliminate the high idle. It temps at around 215 with werks #5 plug and 2013 pipe. Byrons 30% Thanks Ron for all the good info you post on here it's what made me get this motor and helped me tune it.
