I don't think you'll see a noticable difference. The way I see it, at 7000 rpm the 1.432 ratio will be approx. 64 rpm more than the 1.419, which is less than 1%.

However, the difference in the tires I switched to, reduced my gearing by only 3.3%. I noticed I wasn't able to pull you or Marlow on the front straight....with the smaller OD tires I could....

Bye for now.
