Thanks for the advice. Don't know what I will do, (shop is out). But, if I go for the leave the forks on method, what am I measuring? After compressing the forks, the distance from the top of the tube to the top of the oil?
If I pull the tubes and do the full monty, I can go with locoponys's advice and measure the amount taken out.
But with both of those ideas, I wonder if the amount originally put in was correct.
And, what is the margin for error. I remember replacing the fork oil on one of my Hondas back in the 70's. I actually think there was a drain plug at the bottom of each fork. Ended putting in too much oil and blew out the seals.
Don't want to make the same mistake twice.
