Thanks Shawn.

I thought 5th would reduce RPM's significantly. Obviously not. :)

I'll check out your website and when I have a minute, I'll study your
findings. Thanks for providing them.

Yah I find the reverse gear ratio on my air cooled could stand to be lower.

But in regards to the figures in Bentley......

"Final drive 38:7 = 5.428"

What do the first two numbers mean?

Sorry for such an elementary question. :^)

Neil.
