Merry Christmas to all and have a happy and safe new year 

I uploaded the factory manual for the sportsman 850 it covers years 2015 thru 2017 ust needs admin approval.  Hope this help

Your welcome and I hope it helps people  out

I just uploaded the factory service manual for the 2019 sportsman 850/1000. It just needs to be approved by admin

Feel pumps are common issue with these year machines. Check for power to the pump if it's ther remove cap and listen when key is turned on should hear pump prime if you hear gas drain back into tank pump is definitely bad

Can you give us more information  on. Check engine lighrl and no codes. What is the vehicle doing when the light is on. Also if the vehicle  has power steering. Any issues in the 4 wd and power steering could cause the Check engine  light to come on but not show any codes on the speedometer. Sometimes the only way to get the code is with a scan tool

Any accessories on the vehicle? if so check for a draw on the battery with the key off.  The service manual has instructions on how to test  the charging system if the stater tests normal and you have no draws then I would suspect  the voltage regulator is bad. 

Yes the manual  is the same for the 2020 110 efit 

Merry Christmas and happy new year to all. Be safe and have fun

2018 Ace 570

I just uploaded the factory service manual for the 2017-2019 Ace 500/570. It just has to be approved by admin first. Hope it helps you. Let me know if you need anything else

Voltage regulator maybe bad

I have the factory manual if you need it

Is the flywheel keyway intatact?. If the keyway is broken can also get an erratic voltage which can  take out the regulator/rectifier. Also can cause issues with timing and cam walk.  My manual state a 1/4 preload on the spring and that the cover is also a cam thrust plate

what year 500

You are welcome

I am uploading the 2012-2014 factory service manual for the 400/500 Sportsman including the ho edition. It will need to be approved by admin

Have you checked timing? Or for a bad flywheel keyway?

High rpms will cause the primary clutch to partially engage making it hard to shift.

Your welcome
