I just got done adjusting the linkage on my ZL600 EFI and it obviously is not calibrated to the pump. Adjusted it almost 1/4 inch and it gave me about a 50:1 ratio. Before this I was using about a quart of oil every 40 miles...Smokin' big time. This was about a 16:1 ratio.
Don't make any adjustments until you figure out your oil consumption. Find out what the specified gas to oil mixture (ratio) is supposed to be for your sled's oil pump setting (e.g. 50 to 1).
To actually determine how your sled is consuming oil and the gas to oil ratio, do the following:
1) Wait until your oil reservoir gets down a quart or more.
2) Making sure your sled is on a flat and level surface, open the hood and make a mark with a pen or marker on the side of the oil reservoir at the current oil level.
3) Add a quart of oil.
4) Reset your trip odometer to zero.
5) Watch your oil level and when it gets back down to the line you marked, record your trip odometer mileage. This gives how many miles it took to consume one quart of oil.
6) To determine your gas to oil ratio: divide your gas consumption (e.g. 10 mi./gal) by the oil consumption (e.g. 125 mi./qt. which is also 500 mi./gal).
In this example, 10 mpg gas divided by 500 mpg oil is 1 mi. gas/ 50 mi. oil (fraction), or, the inverse is 50 gal. gas / 1 gal. oil (ratio), or, 50:1. You are using 1 part oil for every 50 parts of gas.
