I'm up in Canada, its been a few years already since Yamaha has sold a superjet up here. The dealer that brought them in, brought them up as "used" and pulled a few other strings to get them here because in my area the demand is very very high and they all sold in a couple very quickly. So there is no warranty on it. It's tough to chase a problem that does not happen constantly. When I was riding backwards on the hood and then trying to spin a 360 on the hood and re grab the bars, I fell off a good 20 times and it never had an issue restarting. It's just that one time now and then. it mucks up like this. It hasn't happened close enough to shore yet, to quickly get the hood off and pull plugs or do anything else to see whats going on. It runs and it's set up perfect otherwise. Plugs are a nice chocolate brown. Even checked compression and it's perfect at 150psi per side. Friends that are two stroke guys and also owned or currently own jet skis, have ridden it and said the same thing. "it runs perfect''. Always little to no water under the hood. It's never done it when I ride into shore and kill it with the kill switch. Only when I fall off in the lake. Or the one time when I was idling when I was warming it up for the first time for the day. It only happened twice on Saturday during a whole afternoon of riding. When it does restart it kinda fires a couple of times then finally it fires up like normal. Which is why I originally asked about how they where jetted from the factory, because I thought it was flooding somehow when I was falling off. Being that it may richer with my elevation.
Also being that I am in Canada, it is a two week wait to order any parts. No one stocks anything for a superjet. It can be frustrating to order a part, wait two weeks, nope not it, repeat. That was a big factor in why I opened u the wallet and bought a new ski and left it bone stock.
