    Superjet spark plugs opinion?

    Well, thats part of the problem. It runs very well, (sometimes holds back for .5 sec when you hit the throttle 100% and when engine is cold it will stall a couple of times when trying to get on plane. But after couple of seconds it works great. I just have to be careful with the throttle during...

    Superjet spark plugs opinion?

    Do these spark plugs look like my engine in running lean? Spark plugs are 2 weeks old and used for 3 times i think. And if so, whats te solution? I checked the settings of the carb and they are correct Should i just turn the main jet a little further out. Stock 2016 superjet. I have the feeling...

    Which needle is what (carb question)

    Hello, my 2016 superjet is doing its job really well. But after its first start of the day it holds back (my 2004 SJ did this as wel, but this one is doing it very hard). I can only apply throttle very carefully, or else it dies. After carefully applying throttle for around 30 seconds you can...

    Resistance of a batteryregulator

    Those values in this chart are 100% NOT CORRECT. Atleast the kOhm isnt. I measured 3 voltage regulators by niw, and its all in the MegaOhm range!! Spread the word

    What happens in the superjet when it verheats?

    So what are the factory settings on the carbs of a stock 2016 superjet? The previous owner messed with the settings i believe, because he had the issue that on the first startup of the day (first minute while running) it would bog down when he applied throttle. This problem still exist btw...

    What happens in the superjet when it verheats?

    Well if it had overheated, it would have gone into limb mode right? That was not the case, it was just hard to start after dying. What could be the reason of a seizure? The first thing i did after it died whas trying to turn over the shaft by hand via the water intake. Offcourse i couldnt get...

    What happens in the superjet when it verheats?

    Hello, I am wondering, what happens when the temp sensor of a stock superjet from 2016 gets high/engine gets too hot? Does it activate a rev limiter, or does it short the ignition or something? I ran mine today very hard and pretty long and suddenly it died. Had trouble starting for a while...

    Resistance of a batteryregulator

    Hello, last day my superjet (2004) suddenly stopled cranking when i hit the start button. NOTHING, battery was suddendly completely flat! I changed battery and measured the voltage, but the engine was not charging the battery. So i took apart the electonic box and did some measurements. I...

    Superjet 2004 is not charging

    Its a jetski battery. Made for jetskis, motorcycles etc. Where did you find those values, and why are they different from the values i found? I measured 1.2 Ohm on green-green from magneto

    Superjet 2004 is not charging

    Does someone maybe has a good regulator lying around? Could you maybe check the resistances between the wires and post them? Im curious if the values on the attachment in my prvious post are correct

    Superjet 2004 is not charging

    But the weird thing is the new voltage regulator is also showing weird values when i resistsnce test them. Attachment show the values as they should be but all my measurements are in the MEGA Ohm range, on Both my new and old voltage regulator. I checked the new regulator before i placed it in...

    Superjet 2004 is not charging

    Varta. The battery is not the problem in my opinion. I just replaced the voltage regulator. Before cranking i measured 12.7 V on battery. When i start, it doesnt change. It stays around 12.7 and wobbles up and down. The ski keeps running when i disconnect the batterycables I measured the...

    Superjet 2004 is not charging

    I know that the battery is bad. Thats the reason the ski isnt cranking. But i want to know WHY the battert went bad. Its a new battery, it worked fine, and all of the sudden it stopped working.. so it went bad during my jetski trip. TWICE. Both times were new batteries.

    Superjet 2004 is not charging

    Thanks for your reply. The battery voltage was around 11 volts when it wouldnt start. But it dropped to 2 volts during cranking. Thats way to low. Right now i am looking for the issue in the coil or regulator. Is there a way to test the coil? And what are the specs of the regulator?
