In the process of troubleshooting what I assume is an electrical problem. Full history is in the post http://cfmoto-forum.com/general-discussion/died-(/

Looking to confirm if the stator is the issue but no idea how to check it. Going to check battery voltage while running as well (14.2 - 14.6v i believe is what i'm looking for).

Any and all help appreciated.

Just had a tip from a FB group that another rider had issues with stalling and they replaced the Crankshaft Position Sensor. Apparently if the sensor warms up too much it will shut down the engine. His problem was on a UForce 800 while I have a ZForce 800 but assumes the engines/sensors should be similar if not exactly the same.

Checked voltage output from the 3 yellow wires that connect to the voltage regulator. From doing some digging I think these are how I can check the stator output. Each line has 3 different outputs while engine is running. 5, 7 and 8v. Anyone have knowledge on what values I should be seeing?

Just use the manual and do the tests. I think these are like most others in that they are 3-phase a/c generators so any two should show a current in the 35+ A/C volts range. The manual will give exact numbers. I still think you have a bad main fuse holder..not the fuse, but a bad crimp internally in the holder like so many others. Test it.

Main fuse holder as in the one accessible by removing storage holder in the front correct?  I’ll check that too although it looks like the tech at the dealer did as well seeing as the stowage portion was removed and not put back in. I’ve also just finished pulling the battery and will take it in to be tested just to rule that out.

No. The main fuse is under the driver's seat in the rear compartment. The one with a red/white wire going to it. Turn the lights on and test the power coming in and out of it. If there is like 12.5+ coming in and less on the load side, you have a problem. Of course if it looks all burned and bubbly that a good indicator as well.

I'll check the voltage at that fuse holder later today when I get the chance. I did physically check the fuses at the very start of the problems and they were in good order. Just have not put a meter to them to check voltage.

I just noticed your reply in another thread about the zforce 1000 starting problems and you mentioned the air filter and oiling in that post and it got me thinking. This machine was running top notch and the only thing I had recently done was to remove the stock air filter and clean it. Simple light detergent wash and dry then I put it back on. No oiling, etc at all. Could this be a cause to my stalling issues?

You can not clean the stock paper filter without damaging it. You can clean it's foam prefilter that covers it but not the paper part. Getting it wet will close the pours and starve the engine.  If you have the CFM foam filter, you must use foam filter oil treatment on it after cleaning and drying otherwise dirt will get through the media and destroy the engine. Stuff gets through all CFM filters as is anyway, that why we highly recommend switching to Unifilter. This should have been your first mod.

ok so i've ordered a UNI filter as a replacement so that is taken care of.

Do you think this could be the problem that causing it to stall out all the time? If so then I'll wait for the new filter to get here and try it out to confirm. If it doesn't work then i'll have to visit a different dealer to see if they can rectify the problem.

If the paper filter became wet or oil soaked it would close the pours and starve the engine. Otherwise, I don't think so.
