I'm putting a SN together for my son. Mint '94 that I had in the shed for 20 years.I bought it after kid sunk it. I took the engine apart and it's been sitting ever since. It was set up nice for back in the day. I had a nice 760 engine from wrecked waverunner that I just put in the Sj. After I installed the B pipe and I saw that the worked engine(apart in a plastic tub) had a R&D head. I gotta put this head on right?
SN Sj 760 install

raised compression with b-pipe forces different jetting, if u eliminate the head ( whats the dome size ? ) the compression will be lowered and possible carb adjustments necessary, raised compression does not mean u have to feed it with race gas ...all depends on PSI
