In what gear?

:SM:

1995 should be 3.15:1 ratio, right?

At 70mph, I think you're close to 2952 rpm.

2.925:1

1995 has a 65 tooth rear, correct?

Yes, I thought that was the year they used the 65T rear pulley. So 1.54:1 primary, and 2.03:1 final drive, equals 3.13:1. I think...

Are you sure it's not (36/25)x(65/32)=2.925 ?

This (http://www.bigboyzheadporting.com/Gearratio.htm) is usually correct.  It wouldn't stay set on 95 Softail when I pasted it because I have been using the 09 up page so much.  If you reset it Ohio has the ratios right.

Ah yah. I forgot. Doh! First year for the 1.44:1 primary. I stand corrected!
