I've changed the plugs on mine. It takes about 45 minutes per motor. You have to take off the lower cowling (or remove bolts and spread the 2 halves) to effectively get to the bottom 2 plugs. Otherwise you will have to unplug several of the air and fuel injectors to get to each plug as well. Its pretty funky in there. How is your battery? Opti's won't start/run worth a shite on a failing/weak battery. Need 1000 MCA minimum.
This. also the fuel pump has a very fine screen that can plug up. With E10 fuel and alum fuel tanks, shite happens and a white power builds up on the fuel pump screen. Do make sure your fuel filter is clean and also add a prefilter if you don 't have one. Make sure thr prefilter is 3/8" in/out fittings.
