Anyone experiencing any overheating issues with the M8 117" or the S&S 128" kit?

Looking to get into a 2020 CVO but my experiences with the heat coming off the 110" have me hesitating.

I found one bike with a 128" S&S already installed so curious how these new M8 motors are handling the heat.

Is your bike choice water or air cooled? That will affect how the riders feel. You are speaking about radiant heat not engine overheating an engine.

The 110's I've had experience regularly overheated. Just want to make sure the M8 and big bore kits don't result in the same.

As long as they do not use a canned map and have a proper flash tune to richen up the fuel a little they are fine. The water cooled models do give off a lot of radiant heat however and riders think they are hot and really the fans are just doing their job
