Sportsman 800 Common Issues List

Does anyone know if there is a list of COMMON issues faced by the Sportsman 800 HO? I’m pretty sure a lot of the issues would cross to the 500’s, as well, and possibly others.

I’m not talking about a random broken CV shaft or boot, or a bad thermostat, etc. If there is another thread or sticky or anything, please include the link. I wasn’t able to find one specific to the 800 HO.

I have my 2008 Sportsman 800 torn apart for a Fuel Pump replacement and would like to know if there are any other repairs I should perform in the downtime instead of IF they occur later.

Here is what I have. If you have others, please let me know.

  • Overheating – Radiator clogging.
  • Overheating – 25A self resetting circuit breaker corroded
  • Overheating – The impeller on the water pump warps
  • Fuel Pump – Gets hot and stops working until cooled or quits all together
  • Right Leg Heat – Hot air around exhaust and from radiator exits at the right ankle.
  • Melting plastics – Exhaust runs VERY close to plastics causing melting
  • Motor Mount breaks – I have kept an eye on mine without issue, but there are several posts about it if you do a google search.
  • TBAP wiring – Wires separate from the connector and either stops functioning or starts to melt the connector
  • TPS – Improper adjustment from the factory/dealership
  • Breather Oil Leak – Platsic breather on top of the motor warps and begins to seap oil
  • Clutch cover sealing – The clutch cover and the clutch backing plate are not sealed well, or at all, letting water into the clutch/belt system
  • Ignition Coil wire harness/connector – The harness is traditionally pulled too tight causing stress on the connector at the coil and causing a no spark issue

I’ve ran into MOST of these and fixed them by searching this and other sites. So I know the fixes are available and am not looking to get into that kind of detail. Just a list of the problems this model runs into so I can either watch out or fix it ahead of time.

And yes I know it’s OLD and I could upgrade to the 850/1000 or buy a rzr, but aside from looking out for the known gotcha’s it doesn’t give me many headaches.

Thanks in advance!!!
