SX/SXi/SXi Pro 750 sx runs for 3-4 mins under load then dies, have to choke, fires right back up...

ski runs great through out the power band, but after riding 3-4 mins it shuts down "starved for fuel? overheating?"


then i have to choke it and throttle it while holding the choke to get it back for another 4-5 mins.... fires right up instantly with choke..


the left side pisser is or was drizzling water last time i checked... right side has nothing coming out.. just had the head off all the jackets were clean, same issue before as well.....


any advice pro's? thanks

Well the pisser on the right hand side is just a drain for your fuel cover area so there really shouldn't be anything comming out that. However I'm not really sure why your having engine trouble.

Check compression if you get a chance, see if it's low...maybe rebuild the carbs too, I had a similar issue on a dual carb sxi, and a rebuild solved the issue....that and when I tore it apart I found one carb the choke linkage wasnt working right so it was partially choked all the time, so I removed the choke and installed a primer. Which is way nicer anyways, good luck bro.

just had the head off, it was spotless... the ski sat for about 4 years before i got it so im thinking maybe theres some trash in the carb.. but! have a sbn44 on the way any day now so ill report back!
