Me too. My epic Flame TS2 is set at 8K . I will lower that down to 7500 probably and taper the timing down to 10 degrees advance as I am running 50/50 race gas at the moment, I have not had any flat water to hold it wide open yet hopefully this weekend give it a try .Cool build!
I'm running an ET 967 in my surf ski, really interested in how one will hold up to sustained high rpm's!!!!
What's your rev limit set at?
