I bought a 2015 CVO Roadglide and I live in Palm Springs, Ca. As summer started to arrive 112 degrees plus. I was experiencing several runability problems with my bike. The rear cylinder shutdown of course and something I didn’t expect was vapor lock. The engine was stalling at almost every stop light and would be really hard to start. After talking to Harley, and being told it was operating as prescribed…I started looking for fixes. I called many companies and found that they were not even interested in talking to me and then I came across your website. Not seeing anything for my bike I called Ultracool. Larry and Robert took me under their wings and I brought the bike to ultracool. After my visit and installation of the cooler I was still worried that it would not be enough to keep the bike cool. So off I went back to Palm Springs and hit the 100 degree temps as I entered the valley. At the first stop light I heard the fans running and the bike was running well. The rear cylinder didn’t even shut down!!! It was a quick light so I decided to run around through the stop and go traffic to put it to the test….It never skipped a beat! I really could not believe it. The temps have risen to over 120 degrees this past two weeks and although it is hard to ride in this kind of heat this bike is my main transportation. The oil cooler works better than I could have imagined and the problems I was experiencing have all disappeared. Yes even in this hot hot climate it is running great. I want to say thanks to Larry and Robert for taking the time out of their busy schedule to help me. If you don’t have one of these coolers…get one!!! Ultracool has the corner on customer service in my book. They went above and beyond to help me and I will recommend them to anyone having heat problems on their Harley.
