    update: went to show a buddy what the scramblers issue was and it fired up. it idles rough still and only runs on one cylinder but at least its running. i guess the ecu just had to have a while to reset itself? i also think i blew the fuse when i installed the last TPS incorrectly (reversed two of the wires). also the code 520 194-7 (manual says stuck throttle) is the only code on the bike now, the two for the injectors are cleared
  2. JacobSlabach
    alright theres also one more thing ive seen on all the polaris bikes but not sure what it is ill take a picture of it and post it. i traced the wires from the little black box (pretty sure its a relay) and wires run out of it to the left handlebar and the the other wires run to the headlights so i thin its just the headlight low beam/high beam relay and the headlights work as they should. im with you on the wiring if id have known it wasnt just a faulty TPS on this bike i wouldnt have bought it lol
  3. JacobSlabach
    alright makes sense. ive been through the whole wiring harness and nothing seems worn or bare. traced all the wires and the ground wires from the injectors run directly to the ecu. positives run to the efi relay which i switched with another relay to make sure its good and no change there. theres a black box in the wiring harness that has wires chopped and reconnected to it im curious what that is. ...or if it has anything to do with my issue.. and i swapped the ecu to my other scrambler LE and it ran just fine, used and tried averything i could think of and it checked out
  4. JacobSlabach
    update: i found that the 20a efi fuse was blown so i replaced it and now the fuel pump comes on with the key but still has the same engine lights and wont fire.
  5. JacobSlabach
    another thing i just realized while looking through the service manual is i dont hear the fuel pump coming on when i turn on the ignition. the plug is hooked up to the pump and i do have the airbox installed (it has the idle air control valve on the side so it has to be installed and hooked up for the pump to come on)
  6. JacobSlabach
    alright will do, also found that theres no spark either. so no spark and no fuel. it has compression and the timing is good. could the TPS being out of adjustment make it not get spark or fuel? it was pulse-running when i bought it (pulsed at idle and i couldnt give it more then 1/4 throttle without it dying)
  7. JacobSlabach
    Got two codes I’m tryna figure out both have to do with the injectors. See attached pic. Any ideas as to what would cause this?
  8. JacobSlabach
    yea and even with the 850s, its hit or miss and i think with the latest years the issue of the warped belt boxes has been fixed. but for anyone who does have a leak in the belt box, check for cracks (if your bike is used or has blown a belt recently) and check that the rubber gasket is not twisted or damaged and for me if i was knowingly going to take the bike deep, i would go ahead and replace the airbox and belt box gasket with a aftermarket thicker, twist resistant gasket
  9. JacobSlabach
    thats only with the 850s that sometimes come from the factory with warped belt boxes. the 570s are tight, but every belt box will leak if the seal is not correctly repacked when you pull it apart. take the extra 5 mins to make sure the seal is not twisted and you should be good to go- same deal with the air box lid. for some people who like to go deep all the time, they will go and purchase an aftermarket seal thats thicker and wont twist and leak like the oem ive had my 570 4 foot in water for multiple minutes at a time and not a drop has ever got in the belt box have also had my 850s belt box under water several times too without any issue

    great looking bike!

    got another question on the same lines at the motor oil is how often do you all change youre diff fluid and trans fluid on your bikes and what do you use?
  13. JacobSlabach
    update on this bike, found a wiring diagram, checked wiring, and its all good. swapped ECUs with my other scrambler and the ECU is good. took the bike to my local polaris dealer to dial in the tps and they charged me $100 to say the diagnostic tool said the new tps was toast. so back to the drawing board. ive heard of the timing gear on the cam jumping time on these machines so that may be an issue.. will check that also.
  14. JacobSlabach
    unless the wiring has been tampered with i dont think you have a bigger issue on youre hands, i would guess the kill switch got bumped to where it was between the on setting and one of the off settings and started creating heat and then melted itself. only other place i could think of would be if youre battery terminals are loose AT ALL, they can cause spikes up and down in voltage, but that usually only cause the 4w not to run or not to charge the battery, not a short somewhere..
  15. JacobSlabach
    alright update on the foreman, ive ordered a rod kit and new oil pump and im waiting on earning a little extra cash to buy a shop press and then im hopefully getting going on rebuilding the crankshaft
  16. JacobSlabach
    i had a 110cc chinese 4w and it had a limiter in the ecu where if i gave it full throttle in the forward gear it would bog and die, i think youre running into the same issue.. they are very annoying because it keeps the atv from popping wheelies but also keeps it from having max power for hills and whatnot. youre also probably experiencing bogging from the carburetor like @davefrombc said, these chinese atv's weak point is the carburetor and theyre very hard to tune just right so that itll actually run strong
