ok just picked up a stock running 86 what should i do now. im in the process of taring it down, alls good still. Im filling the stock intake on top of hood and ran new breather lines to the water traps from inside the back of the hump in the hood. I used the stock through hull fuel fill fitting to relocate the pickup to swap to internal fill so i can shave the fill port and fill it. ??cutting the last 1.5in off the end of the ski?? adding 2in to stock exhaust cone, stinger and bypass the pipe. I like to keep stock bilge but whats the best way to get dual cooling run? 44m sbn on its way with aftermarket 44m intake, or so im told, and hydroturf the seat,anyone done this? its a surf ski and im not gonna be sitting down. should i mill the head and bump it to 175psi? i want to run the 650 as long as i can as hard as i can. any other ideas? if you say swap it send me the 750 and i will gladly send you the 650
