What Year Sled?
From 1980 through 2000, I think they all have the same oil pump.
And all the oil pumps I have seen have 2 lines engraved into the lever, and 1 line on a boss on the pump. At idle, 1 line should line up with line on boss, at full throttle, the other should line up with it. Of course, the more you open the throttle, the more the pump pumps oil. So, you can determine if the lines don't line up, if the pump is more lean or more fat.
If I knew how to attach a picture.. I could.. of my oil pump and the lines I am referring too.
Or you could send me your e-mail..
I will try to read the destruction to add a pic...
