1998 ZR 600 efi won't rev

  • I am having a problem with my '98 Zr 600 EFI.  Runs great right up to 4600 rpm then bogs.  Replaced stator and unhooked throttle safety switch with no help.  Does anyone have any idea whats wrong?

  • 2 things I can think of right off are   What is the actual fuel pressure and look to see if you mashed the muffler outlet shut by hitting something.Take the pipe out of the muffler and  see if it will rev. My bet is on the outlet smashed shut.

  • TAKE THE BELT OFF AND HOLD IT WIDE OPEN TO SEE WHAT KIND OF RPM'S IT WILL PULL WITH NO LOAD. REPOST YOU FINDINGS AND I'LL LET YOU KNOW WHAT TO DO NEXT
  • Even with the belt off it only revs to about 4600-5000. It hits the engagement speed and sounds like someone hit the kill switch but keeps running.  The exhaust is open not bent in.  I checked the fuel pressure it is about 40 psi.  The sled is completly stock.  Would installing a Hot Rod chip help anything?
  • I just rechecked the rebuilt stator and the resistance between the wires you test was about the same for both.  I am thinking I got a bum stator still.  Am contacting where I got it to see what they're going to do.
  • You could do like i did with my f7 and pull the fuel line off and let some gas spill into the bellypan and then "accidentally" drop your trouble light in there. Just stand back a little. That was the best fix i ever did. People think they're fast when they run, mine wasn't fast until she burnt. Man was that fast. Burnt my eyebrows right off! Burnt my hair a little too but thank god that all grew back. 
  • Where do you live at,

    I have one that has just been re wound that I know is good, who did your rewind?

    I have a couple for sale with an exchange if you are interested in one.

    If it looks stock...... It must be ???????
  • If it backfires it's the stator,

    I have seen a lot of them come in my shop doing the same thing

    If it looks stock...... It must be ???????
  • I live in central NY.  It backfired like crazy before I changed the stator.  I bought the stator from Als Snowmobile.
  • Your used stator is bad, I have one that has been rewound by stator corp, if you are interested in it.

    He has done at least 25 of them for me and I have never had a problem with his work.

    $210 exchanged shipped to your door, two year warrenty after you send me yours.

    Was the post melted off the stator ???

    I have seen the melted post fry the ecu before, Is yours a square symbol ?

    I have a used one of those ???

  • I have a 99 ZR 600.  Had it in the shop every year, last 2 years.  Told each time, it is fixed, charged hundreds, just got back from Michigan UP, SAME issue.
    Sled starts fine, idles fine, runs fine, then trouble.  I can get teh sled to @ 40-50MPH, 1/2 throttle, any more, and it bogs down, tries to die.  Often will back fire.  Tried new gas, higher octane, fuel injector cleaner, iso heat, last year the deal "fixed it" at teh end of the year.  They found a bad temp. sensor, um BULL****!  I put 5 miles on it (first time riddne this year), and it was doign it again!
    I have suggested the stator, they have yet to act on that.
    What can I do?   would rather not drop $500 plus labor into this sled.  It only has 2500 miles on it.  I only put on a coupld hundred a year.
    Suggestions?

  • How hard is it to replace the stator yourself?

    Sits behind the recoil and such, correct?  Any special tools to do this repair?

  • I got my 1998 ZR600 efi running finally.  Replaced the stator, throttle bodies, and timing sensor.  The throttle position sensor was rubbing on the steering and had a bare wire.  The new throttle bodies have the sensor plug 90 degrees from where the original one was.

    The stator is really easy to change.  The only special tool you might need is a flywheel puller.  You have to take the recoil off, then pull the flywheel off, Then take three allen head bolts out of the stator and remove it.
  • just replaced a stator in a 98 zr600 from stator corp,price is right they do good job. they sent me a fax of a picture what seems to happen is heat build up kills stator so what you do is drill 5-6 small holes 1/8" in bottom of  housing that surrounds stator area and shim recoil with small washers out about 1/8" to let air in and cool stator,just my 2cents.       CHIP
