How to check water pump?

I have a 2005 sportsman 700 twin efi. I'm changing out the valve cover to the metal one now and I was reading about the plastic water pump propeller.. I did remove the radiator cap and look for flow. But I can't tell if much or anything is moving. Anyone have a video I could compare my flow to? And if not, If I drained the fluid and removed the water pump cover and check to make sure the nut is tight and the fins aren't destroyed, am I going to disturb any seals if there is nothing wrong with the propeller?

Thank you in advanced

Interchangeable lift?

So a buddy of mine is letting me get a super atv 6" lift off of his 2014 sportsman 850.
Will this lift and axles fit on my 2014 sportsman 570 ?

03 Polaris Magnum 330 4×4 CDI/ECM issue

I purchased this bike for my daughter earlier this summer as a basket case with a spun rod bearing and finally got around to the rebuild last week.

After getting the engine taken care of and back in the bike I started it up without any issue. I was letting it sit and idle to get up to temp and saw smoke start pouring from the front (the CDI box). I was going to just order the CDI but I want to make sure I am fixing the issue not just buying a new CDI to cook. I have read there are some issues with the voltage regulators/ECM on these bikes but i cant see how to test it. As soon as I turn on the key the CDI starts smoking so I cant run it.

ECM Part Number on this model is 4010944

Thoughts?
