I have the 60HP shot and last time out was seeing 7800-7950 rpm off and 8400 rpm after a few seconds on the button. Also have the 13.6:1 PA head and ride around 6000' wmixing in 5L of VP110 in an empty tank with 91 shell. 32:1 VP110 and oil in the little bottle. Never seen a rev limiter or DET so far.
Bought a case of torco accelerator and am going to start putting 8oz per a tank instead of mixing in the VP and will buy C16 to fill the little bottle.
