Problems with SLTX1050

[jh3586]

i tried to get some help from go-polaris-forum, but no replies. hope someone here can help me.
I bought recntly 96 model SLTX1050 ( 56 hours ). First day it ran nice, took over 7000 rpm and went a bit over 50 mph ( dunno whats the top speed, but it ran nice ). 2nd day, it wasnt working so well anymore, only few times took over 7000rpms when driving full throttle. 3rd day it didnt take more than 6400 rpms and only went about 40 mph, but no other problems, only problem was that about 1000 rpm was missing. And when driving full throtle it sounded like there is speed limiter cutting off the rpms or like there is something wrong with the carburators, like it cant get gasoline.
Ive heard that quite many people have excatly this kind of problem and ive heard many repair suggestions, but is there only ONE thing i should repair or should i tear the whole engine into pieces and check everything ? by now i have rebuilt the carbs, changed plugs, cheched compression (125-123-124, all good i think) What should i do next ?

Thansk for advance

Re: Problems with SLTX1050

Your compression is good, and if you're sure you rebuilt the carbs correctly then the first thing I would look at is the stator and CDI. Both are notorious for going on the 1050. I would change your stator first. You should know that even the parts you get today are not 100% reliable. One of our guys here has gone through several over the years on his 1050, but there's nothing you can do.

Thank you for replying

Maybe a stupid question, but how do i know if my CDI or stator is working correctly or not, is there a way to check those without any special equipments ?

Re: Problems with SLTX1050

Unfortunately no, you have to swap the parts out to test.

Re: Problems with SLTX1050

This is for testing the trigger coils.

Disconnect the stator wires and attach a 9 volt battery to the brown and black wires from the stator plate.
Connect one lead of the ohmeter to the black wire and connect the other lead to the red, green or blue wire.

Rotate the flywheel slowly (remove plastic cover over engine coupler and rotate from there) while watching for movement at the ohmmeter. It should show infinity until the magnet passes the sensor at which time it should drop to under 25 ohms as you keep rotating it should go back to infinity.

Repeat for the other wire colors. You should get a sharp movement from infinity to roughly 25 ohms as the engine is rotated.

The trigger coils are hall effect sensors and require a constant 12 volt source which comes from the brown wire out of the CDI module. When a magnet is passed by the sensor, the sensor becomes conductive and triggers the release of the energy stored in the capacitor creating the ignition spark.

Re: Problems with SLTX1050

Try replacing the resistor spark plug caps with plain simple ones...it's what will cause problems with the stator as it gets older.

Re: Problems with SLTX1050

Good theory, but not true. Polaris has known about and tried to correct the electronic problem for years. They are up to revision 5 of the stator alone.

Re: Problems with SLTX1050

It's not a theory...it's fact!...and I don't need the condesending remark either!

Re: Problems with SLTX1050

Then tell me how many revisions of the 1050 stator there are :) And why doesn't any Polaris tech or dealer I have ever talked to about it or corresponded to about it via the net ever mentioned it?

Re: Problems with SLTX1050

Don't get me wrong - if this is something official from Polaris R&D I'd love to see specific fixes - we have a ski here that can benefit! Do you have part numbers?

[Jetskimn]

Re: Problems with SLTX1050

Tell me, why does everyone have to be aware or know about something before it's allowed to be true? Maybe if you just try the advice (since it's cheap and easy to do...and it definitely won't hurt anything) and find out for yourself if it works or not...then you can decide for yourself what your opinion is and what you want to tell people.

We'll try it, thanks.

Re: Problems with SLTX1050

Thansk for the replies and intersting conversation. I contacted to one Polaris specialist and he confirmed that the way Jetskimn told to check the stator is the way how it can be tested (knowledge given by technical support from Polaris factory). Also this guy told me test the high-rmp-coil and low-rpm-coil. Can be done like this:
1. Disconnect the stator wires 2.Check the resistance between the black wire and ground, value should be 0ohms 3. Connect the ohmeter between the grey and black wire, value should be 80-130ohms 4. Connect the ohmeter between the black and purple wire, the value should be 1200ohms.

I did what he told me to do, this is what i got:
Trigger coils: blue 26ohms, red 26ohms, green 28 ohms
Rpm coils: blk-grnd 0,1ohms, blk-grey 89,8 ohms, blk-purple 1272ohms.
Too bad i never reached this guy after he gave me the info, but i assume my stator is ok, cause the values are almost what they should be, arent they ?, Jetskimn, you listening?

Re: Problems with SLTX1050

Jetskimm - why are you completely editing your replies? What you have up now is not what you originally posted. Any why did you remove your statement that you work in Polaris R&D and this is a factory fix?

Re: Problems with SLTX1050

Most likely because he gave accurate info and you guys always have a comeback about it wont work, or do it this way. Why is it, that, when someone with knowledge gives it on your site, you always find a way to degrade the info. Spark plugs for one, timing issues,stator test ect. Maybe you should get with Polaris and find out some of the info. For some reason it appears that SBT has a problem with Polaris watercraft. In reality it is some of the best made. They all have issues. ever tried to diagnose an electronic issue with Kawasaki. All they will tell you is change the parts. Polaris gives testing info to their qualified techs and Dealers. Most Dealers wont give it out as it insures them of service jobs and rightfully so. Everyone wants to be the backyard mechanic and get the info free so they can fix it themselves. This is one of the reasons Dealers have a hard time making ends meet. Without service monies to rely on overhead must come from sales of parts or New accessories and New machines.
I applaud jetskimn for his response and dont blame him at all for erasing it once you gave your remarks.
