Hi guys,
First post on the forum after a friend introduced me here. Hopefully one of you guys has a little more two stroke knowledge than me. I have a 99 GSX fuel injected (the 110Hp) model, its a great little machine, and one that i have hardly ever had any problems with. But for about the last two weeks, the Ski has been backfiring at high revs, and blowing alot of white smoke (unburnt fuel?) My initial thought was dirty plugs, so i changed the plugs, and the ski now sounds alot better and cleaner through the lower and mid rev range, but it is still burning alot of white smoke, and still backfires at high revs. I havent had it in the water while it has been doing this so i dont know if that would change anything. Yesterday i took all the sensors that i could find off and cleaned them with some contact cleaner, A guy from sea-doo told me its likely a throttle position sensor problem, i cleaned up the three sensors that i saw off the throttle body, and any others i saw as well. I tried to isolate it and do it one sensor at a time then start it, and once it backfired on startup then just died, but the pop was alot louder than it usually is when it backfires when running. It started again no problems, and still has the same problem. If anybody knows, where exactly is the throttle position sensor located?? is there a way to reset this?? i'm fairly new to pulling apart skis, so if you could include a general location of anything that you think might fix it that would be appreciated. Thanks guys, im desperate to get this thing back in the water.
Thanks Guys.
