Does it slip - not on it's own, you can easily over-ride the friction by simply turning the throttle either way open or close.
too much or too little throttle - up to you. I find it easier to set on my 650 than on my 1000. When using it on the 650, setting the throttle at any position tends to yield a smaller delta +/- on the actual speed with respect to hills and whatnot, where as on the 1000, you have to be a little more precise with setting it, unless you use a lower gear like 4th
The Hex Key shown in the first picture lets you set the clamping force, from then on, it's very repeatable in terms of it's clamping force and friction.
Thanks.
I had the Vista cruise on my older bike and it was never right. When I try locking the throttle, it either accelerated or decelerated. It was never at the right cruise speed. I just used to to move my wrist a bit.
I think I will order the NEP to give it a try
