Picked up this sled, estart starts and runs/ well idles but it seems to be putting out excessive amount of exhaust smoke. I plan on readjusting the pump cable. Heard pull it out of socket and measure somewhere between 19-21 mm, but I suspect the pump if pushing way too much oil. I will pull the plugs to check to see if they are black. I have heard that these era of sleds had oil pump failures, but they at least would go to full capacity?

First starts they all smoke until they are warmed up. could also be a sticky choke. When the pumps go you will tell when they go thru 1 quart in 50 miles.
 
Your oil pump may need to go a little further than what the manual says. Mine was still pretty rich at 29mm (leanest the manual says). I think mine might be at like 32mm and is at 48:1.

Add some oil in your tank, like 1-1.5oz per gallon of gas until you get it dialed in.

Make 2 marks, about 3in apart, on your oil tank. This will allow you to measure the amount of oil you use during your testing. I did 2 gal of gas at a time until I got close to 40 or 45:1. I went to 4 gal during fine tuning to get a better reading.

I have a 94 VMAX 600 for reference. The 95 might have marks on the oil pump for adjusting for WOT. Actual testing/measuring is going to still be best.
 
I agree with all the replies you have gotten so far.

Remember most cheep oils smoke more then the premium oils

What I would do to establish a baseline:
-fill the oil tank
-fill the fuel tank
-ride the sled until the fuel tank is low
-check the oil level occasionally to ensure it does not go dry[unlikely]
-fill the fuel tank again keeping track of how much fuel is added
-fill the oil tank again and measure how much oil was used

Do the math on the ratio of fuel to oil used
ex: 8 gallons burned and 1 quart used
8 gallons = 32 quarts
32 divided by 1 = 32:1 mix ratio
anywhere from 30:1 to 50:1 is in the wheel house for normal

I have always run my two strokes on the richer side towards 32:1 to 40:1
