OK, guess I'll have to do this the right way...
1. Use a jack to ensure that the frame is level (same height from level concrete floor, on BOTH sides).
2. Measure height from floor at:
a)FEL lip
b)FEL lift arms
c)FEL pin cradle
d) any other points that appear significant.
I did some preliminary measurements, and found that --preliminarily, mind you-- that the bucket lift arms and pin cradles are 5/16" lower on the right; also found the frame was 1/8" lower on the right (most likely tires).
That still leaves a difference of 3/16" (lower) on the right.... but I'll check that more thoroughly later. Now that I've begun this, the carb on the rear cylinder of the Virago will have to wait,
and I'll dig into this "FEL not level" thing.
Gary, I realize it may look like the crossbar is level with the FEL, but I'm convinced there's a discrepancy somewhere. I'll try to check it out more..uh.. scientifically.... like an engineer should... later.
Thanks to all for the interest; it really is a bit of a pain to have the FEL always digging in deeper on the right side. I'll get to the bottom of it sooner or later.
