Mine was just causing steering issues. I know if the belt gets glazed on them they throw a miss fire code. Have it happen about every time it needs a new belt.
Saved me a headache ! I jumped brake switch due to a torn line not letting me start the car I was moving the car around forget the I had jumped it trying to figure out what was wrong all I had to do was remove my jump lol 😂 Brain fart
Would appreciate any suggestions. 2012 Polaris 800 EFI hesitates at 45-50 mph. 45 is about 6350rpm. Not really a sputter or cough. Repairman just cleaned throttle body and fuel injectors and said idle air circuit was partially open causing a misfire at that speed. None of the work performed solved the issue. One person suggested the primary and secondary cluthes might be fighting each other. Need to get it fixed pretty quick so we can sell it and move, but I want it to be right. I should also mention that it has full power no issues 0-45. No codes, no engine light. Always at that speed only.Thanks folks. Appreciate anything.
@@davepo6443 I guess I have a few more questions. The guy said your IAC was partially open? Is it mechanical stuck open or is electrically being opened, and if it is electrically opening then is the computer calling for it or is it a voltage bleed over from something else? Just something to look at that needs to be solved. The rpm seems high to me but been a long time since ive been in a 800 to remember. I would definitely look at the clutch and belt. Lots of videos about clutches but look at the snowmobile ones they seem to be more informative. I know belts will cause a misfire code at low speed. I know you said you have no engine codes but I know if something is worn out on your clutch’s it’ll cause hesitations and luckily most of that is a visual inspection. Good luck with it and let me know what you find out on it. Thanks
@@segamodshop1498 Thank You for your response. I have some new information on the 2012 Polaris 800 Razor having issues at 45mph. I was asked if it could go faster than 45mph. Just took it for another test. As usual it hesitates at 45mph. I pushed it on a longer stretch and when it gets to 50mph it stops hesitating. When I get to 55mph it hesitates again. Top speed is 60 mph at a maximum of 6500 rpm. To obtain codes, one video suggested turning the key off and on 3 times and it will show a code. Didn’t see anything pop up when I tried it. I don’t know if this 800 has the ability to display any codes? I’d like to include some responses from folks kind enough to offer suggestions to see if it triggers any other ideas pointing to one thing. The spark plugs were replaced about 1.5 years ago. They were examined recently and found to be good. I still might replace them as that’s a cheaper item. I suppose it could be a bad spark plug wire.. or coil wire. Your thoughts? Suggestions: fuel pressure check, sounds like fuel pump, spray water on spark plug wires and coil wire, Fuel stabilizer, Belt might be slipping, inspect clutches and belts, don’t think its clutch related, sounds like clutches sticking, check belt for damage, weights in primary clutch are too light, was IAC mechanically stuck open or electrically being opened. Thanks again. I’m hoping this new information might directly point to something that I will try and tackle on my own. Taking it in is a last resort for me. I promise, to get back to you once I find the issue! Thank you kindly. Very much appreciated. Dave
@@segamodshop1498 I finally have the answers on the 2012 800 Razor issues. Thank you for your response! Summary for 2012 Razor 800: • Fuel pressure was a consistent 44PSI which is in spec. Previously verified during last repairs. • Spark Plugs were checked during previous repairs and color was a light brown (NGK BKR7E) Plugs replaced in previous repairs Jan. 2023 • TPS set at .730 per factory spec. using TPS TOOL brand meter (specified range is .720-.740 TPS voltage setting controls idle and start up. • Overall TPS voltage affects WOT, but that would be bad TPS unit. • IAC solenoid was partially open because of excessive dirt build up in throttle body. • Injectors were checked and cleaned because fuel goes bad much faster in the summer heat of the desert. • Mass Air Flow sensor was cleaned with MAF sensor cleaner because of dirt and oil build up • UNI brand Air Filter cleaned and treated and intake tract cleaned Diagnosis: • During diagnosis test drive the operators RPM’s were watched closely. • During wide open throttle pass on pavement, engine was at 6400 rpm at 45mph. • 6400rpm is on the rev limiter and that’s the surging feeling. Had to feather the throttle lightly to work towards 50mph and hit 6400 rpm again. Definitely Clutch related (clutches were not serviced in Jan of 2023, only on new belt). CLUTCH INSPECTION ON MACHINE: Secondary clutch was difficult to open for belt removal. Primary Clutch: Needed partial rebuild • Installed new OEM sliders • Rollers in the spider were good • Installed new OEM 2- way bearing • Installed new OEM 23-62 weights (removed 23-58 weights) • Installed new OEM shoulder bolts for the weights Secondary Clutch: Tear Down • Internal Rollers in excellent shape • Excessive dirt and debris in bushing area of moveable sheave resulted in hard to open during belt change, also translates to poor operating results • Replaced Belt Drive • After Clutch servicing engine holds at 6150 rpm during wide open. Wide open throttle RPM/MPH test No issue getting to 55mph, did not try for higher MPH as clutches now hold correct RPM
Good job 👍 got a 2021 XP with 21 hours! Check engine and steering light on!!!
How did you fix it
Same here
What was the issue? Same problem I'm having
When we have problem on the speed senssor.
The rzr can have a misfire?
Mine was just causing steering issues. I know if the belt gets glazed on them they throw a miss fire code. Have it happen about every time it needs a new belt.
What check engine light did you get ?
Don’t remember the exact codes but it was for a speed sensor issue.
Saved me a headache ! I jumped brake switch due to a torn line not letting me start the car I was moving the car around forget the I had jumped it trying to figure out what was wrong all I had to do was remove my jump lol 😂 Brain fart
Did your fuel gauge and everything work?
Yes with my situation those were working

@@segamodshop1498 I finally have the answers on the 2012 800 Razor issues. Thank you for your response!
Summary for 2012 Razor 800:
• Fuel pressure was a consistent 44PSI which is in spec. Previously verified during last repairs.
• Spark Plugs were checked during previous repairs and color was a light brown
(NGK BKR7E) Plugs replaced in previous repairs Jan. 2023
• TPS set at .730 per factory spec. using TPS TOOL brand meter (specified range is .720-.740 TPS voltage setting controls idle and start up.
• Overall TPS voltage affects WOT, but that would be bad TPS unit.
• IAC solenoid was partially open because of excessive dirt build up in throttle body.
• Injectors were checked and cleaned because fuel goes bad much faster in the summer heat of the desert.
• Mass Air Flow sensor was cleaned with MAF sensor cleaner because of dirt and oil build up
• UNI brand Air Filter cleaned and treated and intake tract cleaned
Diagnosis:
• During diagnosis test drive the operators RPM’s were watched closely.
• During wide open throttle pass on pavement, engine was at 6400 rpm at 45mph.
• 6400rpm is on the rev limiter and that’s the surging feeling. Had to feather the throttle lightly to work towards 50mph and hit 6400 rpm again.
Definitely Clutch related (clutches were not serviced in Jan of 2023, only on new belt).
CLUTCH INSPECTION ON MACHINE:
Secondary clutch was difficult to open for belt removal.
Primary Clutch: Needed partial rebuild
• Installed new OEM sliders
• Rollers in the spider were good
• Installed new OEM 2- way bearing
• Installed new OEM 23-62 weights (removed 23-58 weights)
• Installed new OEM shoulder bolts for the weights
Secondary Clutch: Tear Down
• Internal Rollers in excellent shape
• Excessive dirt and debris in bushing area of moveable sheave resulted in hard to open during belt change, also translates to poor operating results
• Replaced Belt Drive
• After Clutch servicing engine holds at 6150 rpm during wide open. Wide open throttle RPM/MPH test
No issue getting to 55mph, did not try for higher MPH as clutches now hold correct RPM
