I own an01 f4i, It's geared -1+2. I'm trying to figure out the actual mileage. The guages read 33,000 but I changed the sprockets at 7,000. Does anyone know what the actual mileage would be?

 

I don't know if my calculations are right, but I'm coming up with, after the gear change, approx 10% increase in the ratio with the new gearing. So with that, I'm coming up with an additional 2826 miles shown due to the gear change, for a total of 30,174 miles actual (23,174 actual after gear change + 7000 original). Don't quote me on this, I don't even know if I did it right... but it seems like it might be right!
