A few years back, I am working up at my place and it starts raining cats and dogs, a guy comes buy and tells me he has had a ski shipped in from Cali to Real Island Marina on Lake Martin, it's a Dave Gordon world finals ski , it has totall loss and has no spark , the guys at Real Island don't have a clue , can I go get it and check it out.
Sure I can so I go to Real Island and pick it up , the ski was put back together by some guy on PWCToday, name of the business was Back in the Day jet ski repair or something like that. he put the two halves of the electrical box back together and piched the wiring, this smoked the ignition coil, so I put a coil in and go water test it, it runs like total crap.
I had something similar happen on my Westcoast dual total loss and knew where to look, first thing I found was resistor spark plugs in it , a big no no on Dyna total loss setups , I replaced those , then I started looking at the nice pretty RED coil wires, also resistor wires, I replaced then with some ho hum looking black Tractor wires, they are solid core copper no resistance , then I check the spark plug caps, also resistor, I used some MSD spark plug caps and headed back to the lake with it.
It did not run that well out of the gate but after a few minutes of carb tuning I had it dialed and it ripped way harder than I ever thought was possible on a 550. I wrapped it up and delivered it to the customer at his aunts place on the lake, I backed it in for him and watched him, I don't think he ever actually rode that ski but it rode him like bucking bronco, quite fun to watch, I watched till I started feeling guilty and left.
