Years ago, I was at a Buell event up in Wisconsin, with lots of factory folks. One of whom was someone who worked in the HD "Product Development Center" (PDC) and was heavily involved in the motor programs. He told me point blank that the SE .497 grind and the N4's are the same cams, despite the minor differences in specs, which he attributed to being spec'ed at different rocker ratios.

This is exactly I was trying to point out... They are the same cams.
Although they can vary from set to set timing wise.

It's now doing 1.5 60 foot times and down to 10.93.
I'm quite pleased with it........... nitrous next ��
Just moved the power band to the left is all.
More midrange power, less top end. Good for a street bike.

Anyone know how much gearing changes affect torque? Specifically imput (primary) sprocket.

Lots of different opinions between here and Badweb, I went with the recommendation of Andrews themselves and as mentioned earlier it seemed to give positive results, I've invested in a Dyna 2000 ignition module now also, let's see what next year brings.
Ps I still haven't weighed it ��
