This is my second unit. I liked the first so much.
These units drop the temp. and when combined w/synthetic oil it is FAR more cool than the standard motor can achieve. It has worked so well that my neighbor has purchased (and LOVES) his for his FLHR.
We have been to Sturgis and a 3200 mile trip this summer w/ ZERO issues and a ULTRACOOL motor !
Highly recommended on ANY air cooled bike. I will put another on my next bike as well.
Thanks guys.
